The System z10 was introduced with a new connectivity
option for LANs – Open Systems Adapter-Express3 (OSA-
Express3). The OSA-Express3 features provide improved
performance by reducing latency at the TCP/IP application.
Direct access to the memory allows packets to flow directly
from the memory to the LAN without firmware intervention in
the adapter.

Just-in-time deployment of IT resources
With the z10 EC, it is now possible to add permanent
capacity while a temporary capacity is currently activated,
without having to return first to the original configuration.
Infrastructures must be more flexible to changing capacity
requirements and provide users with just-in-time deploy-
ment of resources. Having the 16 GB dedicated HSA on
the z10 EC means that some preplanning configuration
changes and associated outages may be avoided. IBM
Capacity Upgrade on Demand (CUoD) provides a perma-
nent increase in processing capacity that can be initiated
by the customer.
The activation of On/Off CoD on z10 EC can be simplified
or automated by using z/OS Capacity Provisioning (avail-
®
able with z/OS 1.9 and above). This capability enables the
monitoring of multiple systems based on Capacity Provi-
sioning and Workload Manager (WLM) definitions. When
the defined conditions are met, z/OS can suggest capacity
changes for manual activation from a z/OS console, or the
system can add or remove temporary capacity automati-
cally and without operator intervention.
IBM On/Off Capacity on Demand (On/Off CoD) provides
temporary capacity needed for short-term spikes in capac-
ity or for testing new applications. Capacity Backup
Upgrade (CBU) can help provide reserved emergency
backup capacity for all processor configurations.
Specialty engines offer an attractive alternative
The z10 EC continues the long history of providing inte-
grated technologies to optimize a variety of workloads. The
use of specialty engines can help users expand the use
of the mainframe for new workloads, while helping to lower
An additional temporary capacity offering on the z10 EC is
Capacity for Planned Events (CPE), a variation on CBU. If
unallocated capacity is available in a server, it will allow the
maximum capacity available to be used for planned events
such as planned maintenance in a data center.
®
the cost of ownership. The IBM System z specialty engines
can run independently or complement each other. For
example, the zAAP and zIIP processors enable you to pur-
chase additional processing capacity exclusively for spe-
cific workloads, without affecting the MSU rating of the IBM
System z model designation. This means that adding a
specialty engine will not cause increased charges for IBM
System z software running on general purpose processors
in the server.
By having flexible and dynamic configuration definitions,
when capacity is needed, activation of any portion of an
offering can be done (for example activation of just two
CBUs out of a definition that has four CBUs is accept-
able). And if the definition doesn’t have enough resources
defined, an order can easily be processed to increase the
capacity (so if four CBUs aren’t enough it can be redefined
to be six CBUs) as long as enough server infrastructure is
available to meet maximum needs.
All activations can be done without having to interact with
IBM—when it is determined that capacity is required, no
passwords or phone connections are necessary. As long
as the total z10 EC can support the maximums that are
defined, then they can be made available.

In order of introduction:
The System z10 Integrated Information Processor (zIIP) is
designed to support select data and transaction process-
ing and network workloads and thereby make the consoli-
dation of these workloads on to the System z platform more
cost effective. Workloads eligible for the zIIP (with z/OS
V1.7 or later) include remote connectivity to DB2 to help
support these workloads: Business Intelligence (BI), Enter-
prise Relationship Management (ERP), Customer Relation-
ship Management (CRM) and Extensible Markup Language
(XML) applications. In addition to supporting remote

System z on IFLs, to operate z/VSE and z/OS on CPs,
to offload z/OS system software overhead, such as DB2
workloads on zIIPs, and to offer an economical Java exe-
cution environment under z/OS on zAAPs, all in the same
z/VM LPAR.
Available on System z since 2004, the System z10 Applica-
tion Assist Processor (zAAP) is designed to help enable
strategic integration of new application technologies

point operations. This is expected to be particularly useful
for the calculations involved in many financial transactions.
The z10 EC continues the line of upward compatible main-
frame processors and retains application compatibility
since 1964. The z10 EC supports all z/Architecture-compli-
ant Operating Systems. The heart of the processor unit is
the Enterprise Quad Core z10 Processor Unit chip which
is specifically designed and optimized for mainframe sys-
tems. New features enhance enterprise data serving per-
formance as well as CPU-intensive workloads.
Decimal calculations are often used in financial applica-
tions and those done using other floating point facilities
have typically been performed by software through the
use of libraries. With a hardware decimal floating point
unit, some of these calculations may be done directly and
accelerated.
The z10 EC, like its predecessors, supports 24-, 31-, and
64-bit addressing, as well as multiple arithmetic formats.

Liberating your assets with System z
Enterprises have millions of dollars worth of mainframe
assets and core business applications that support the
heart of the business. The convergence of service oriented
architecture (SOA) and mainframe technologies can help
liberate these core business assets by making it easier
to enrich, modernize, extend and reuse them well beyond
their original scope of design. The z10 EC, along with the
inherent strengths and capabilities of a z/OS environment,
provides an excellent platform for being an enterprise hub.

IBM’s commitment includes designs and development
practices intended to prevent unauthorized application
programs, subsystems, and users from bypassing z/OS
security—that is, to prevent them from gaining access,
circumventing, disabling, altering, or obtaining control of
key z/OS system processes and resources unless allowed
by the installation. Specifically, z/OS “System Integrity” is
defined as the inability of any program not authorized by
a mechanism under the installation’s control to circumvent
or disable store or fetch protection, access a resource pro-
tected by the z/OS Security Server (RACF), or obtain con-
trol in an authorized state; that is, in supervisor state, with
a protection key less than eight (8), or Authorized Program
Facility (APF) authorized. In the event that an IBM System
Integrity problem is reported, IBM will always take action to
resolve it.

Units (PUs) has grown from 54 to 64, and memory has
increased from 128 GB per book and 512 GB per system
to 384 GB per book and 1.5 TB per system.
For LAN connectivity, z10 EC provides a OSA-Express3
2-port 10 Gigabit Ethernet (GbE) Long Reach feature along
with the OSA-Express3 Gigabit Ethernet SX and LX with
four ports per features. The z10 EC continues to support
OSA-Express2 1000BASE-T and GbE Ethernet features,
and supports IP version 6 (IPv6) on HiperSockets. OSA-
Express2 OSN (OSA for NCP) is also available on System
z10 EC to support the Channel Data Link Control (CDLC)
protocol, providing direct access from the host operating
system images to the Communication Controller for Linux
on the z10 EC, z10 BC, z9 EC and z9 (CCL) using OSA-
Express3 or OSA-Express2 to help eliminate the require-
ment for external hardware for communications.
The z10 EC will continue to use the Cargo cage for its I/O,
supporting up to 960 Channels on the Model E12 (64 I/O
features) and up to 1,024 (84 I/O features) on the Models
E26, E40, E56 and E64.
Additional channel and networking improvements include
support for Layer 2 and Layer 3 traffic, FCP management
facility for z/VM and Linux for System z, FCP security
improvements, and Linux support for HiperSockets IPv6.
STP enhancements include the additional support for NTP
clients and STP over InfiniBand links.
HiperDispatch helps provide increased scalability and per-
formance of higher n-way and multi-book z10 EC systems
by improving the way workload is dispatched across the
server. HiperDispatch accomplishes this by recognizing
the physical processor where the work was started and
then dispatching subsequent work to the same physical
processor. This intelligent dispatching helps reduce the
movement of cache and data and is designed to improve
CPU time and performance. HiperDispatch is available
only with new z10 EC PR/SM and z/OS functions.
Like the System z9 EC, the z10 EC offers a configurable
Crypto Express2 feature, with PCI-X adapters that can
be individually configured as a secure coprocessor or
an accelerator for SSL, the TKE workstation with optional
Smart Card Reader, and provides the following CP Assist
for Cryptographic Function (CPACF):
Processor Units (cores) defined as Internal Coupling
Facilities (ICFs), Integrated Facility for Linux (IFLs), System
z10 Application Assist Processor (zAAPs) and System
z10 Integrated Information Processor (zIIPs) are no longer
grouped together in one pool as on the z990, but are
grouped together in their own pool, where they can be
managed separately. The separation significantly simpli-
fies capacity planning and management for LPAR and can
have an effect on weight management since CP weights
and zAAP and zIIP weights can now be managed sepa-
rately. Capacity BackUp (CBU) features are available for
IFLs, ICFs, zAAPs and zIIPs.
• DES, TDES, AES-128, AES-192, AES-256
• SHA-1, SHA-224, SHA-256, SHA-384, SHA-512
• Pseudo Random Number Generation (PRNG)
z10 EC is designed to deliver the industry leading Reli-
ability, Availability and Serviceability (RAS) custom-
ers expect from System z servers. RAS is designed to
reduce all sources of outages by reducing unscheduled,
scheduled and planned outages. Planned outages are
further designed to be reduced by reducing preplanning
requirements.

With the logical partition (LPAR) group capacity limit on
z10 EC, z10 BC, z9 EC and z9 BC, you can now specify
LPAR group capacity limits allowing you to define each
LPAR with its own capacity and one or more groups of
LPARs on a server. This is designed to allow z/OS to
manage the groups in such a way that the sum of the
LPARs’ CPU utilization within a group will not exceed the
group’s defined capacity. Each LPAR in a group can still
optionally continue to define an individual LPAR capacity
limit.

Additionally, several service enhancements have also
been designed to avoid scheduled outages and include
concurrent firmware fixes, concurrent driver upgrades,
concurrent parts replacement, and concurrent hardware
upgrades. Exclusive to the z10 EC is the ability to hot swap
ICB-4 and InfiniBand hub cards.
Enterprises with IBM System z9 EC and IBM z990 may
upgrade to any z10 Enterprise Class model. Model
upgrades within the z10 EC are concurrent with the excep-
tion of the E64, which is disruptive. If you desire a con-
solidation platform for your mainframe and Linux capable

r
current application workloads in a cost-effective manner. If
your traditional and new applications are growing, you may
find the z10 EC a good fit with its base qualities of service
and its specialty processors designed for assisting with
new workloads. Value is leveraged with improved hardware
price/performance and System z10 EC software pricing
strategies.
Some of the significant enhancements in the z10 EC that
help bring improved performance, availability and function
to the platform have been identified. The following sections
highlight the functions and features of the z10 EC.

z10 EC Design and Technology
The System z10 EC is designed to provide balanced
system performance. From processor storage to the
system’s I/O and network channels, end-to-end bandwidth
is provided and designed to deliver data where and when
it is needed.
The design of the MCM technology on the z10 EC pro-
vides the flexibility to configure the PUs for different uses;
there are two spares and up to 11 System Assist Proces-
sors (SAPs) standard per system. The remaining inactive
PUs on each installed MCM are available to be charac-
terized as either CPs, ICF processors for Coupling Facil-
ity applications, or IFLs for Linux applications and z/VM
hosting Linux as a guest, System z10 Application Assist
Processors (zAAPs), System z10 Integrated Information
Processors (zIIPs) or as optional SAPs and provide you
with tremendous flexibility in establishing the best system
for running applications. Each model of the z10 EC must
always be ordered with at least one CP, IFL or ICF.
The processor subsystem is comprised of one to four
books connected via a point-to-point SMP network. The
change to a point-to-point connectivity eliminates the need
for the jumper book, as had been used on the System z9
and z990 systems. The z10 EC design provides growth
paths up to a 64 engine system where each of the 64
PUs has full access to all system resources, specifically
memory and I/O.
Each book can support from the 16 GB minimum memory,
up to 384 GB and up to 1.5 TB per system. 16 GB of
the total memory is delivered and reserved for the fixed
Hardware Systems Area (HSA). There are up to 48 IFB
links per system at 6 GBps each.
Each book is comprised of a Multi-Chip Module (MCM),
memory cards and I/O fanout cards. The MCMs, which
measure approximately 96 x 96 millimeters, contain the
Processor Unit (PU) chips, the “SCD” and “SCC” chips of
z990 and z9 have been replaced by a single “SC” chip
which includes both the L2 cache and the SMP fabric
(“storage controller”) functions. There are two SC chips
on each MCM, each of which is connected to all five CP
chips on that MCM. The MCM contain 103 glass ceramic
layers to provide interconnection between the chips and
the off-module environment. Four models (E12, E26, E40
and E56) have 17 PUs per book, and the high capacity
z10 EC Model E64 has one 17 PU book and three 20 PU
books. Each PU measures 21.973 mm x 21.1658 mm and
has an L1 cache divided into a 64 KB cache for instruc-
tions and a 128 KB cache for data. Each PU also has an
L1.5 cache. This cache is 3 MB in size. Each L1 cache
has a Translation Look-aside Buffer (TLB) of 512 entries
associated with it. The PU, which uses a high-frequency
z/Architecture microprocessor core, is built on CMOS 11S
chip technology and has a cycle time of approximately
0.23 nanoseconds.
The z10 EC supports a combination of Memory Bus
Adapter (MBA) and Host Channel Adapter (HCA) fanout
cards. New MBA fanout cards are used exclusively for
ICB-4. New ICB-4 cables are needed for z10 EC and are
only available on models E12, E26, E40 and E56. The E64
model may not have ICBs. The InfiniBand Multiplexer (IFB-
MP) card replaces the Self-Timed Interconnect Multiplexer
(STI-MP) card. There are two types of HCA fanout cards:
HCA2-C is copper and is always used to connect to I/O
(IFB-MP card) and the HCA2-O which is optical and used
for customer InfiniBand coupling.
Data transfers are direct between books via the level 2
cache chip in each MCM. Level 2 Cache is shared by all
PU chips on the MCM. PR/SM provides the ability to con-
figure and operate as many as 60 Logical Partitions which
may be assigned processors, memory and I/O resources
from any of the available books.

z10 EC Model
The z10 EC has been designed to offer high performance
and efficient I/O structure. All z10 EC models ship with two
frames: an A-Frame and a Z-Frame, which together sup-
port the installation of up to three I/O cages. The z10 EC
will continue to use the Cargo cage for its I/O, supporting
The z10 EC has five models offering between 1 to 64 pro-
cessor units (PUs), which can be configured to provide
a highly scalable solution designed to meet the needs
of both high transaction processing applications and On
Demand Business. Four models (E12, E26, E40 and E56)
have 17 PUs per book, and the high capacity z10 EC
Model E64 has one 17 PU book and three 20 PU books.
The PUs can be characterized as either CPs, IFLs, ICFs,
zAAPs or zIIPs. An easy-to-enable ability to “turn off” CPs
or IFLs is available on z10 EC, allowing you to purchase
capacity for future use with minimal or no impact on
software billing. An MES feature will enable the “turned
off” CPs or IFLs for use where you require the increased
capacity. There are a wide range of upgrade options avail-
able in getting to and within the z10 EC.

up to 960 ESCON and 256 FICON channels on the Model
E12 (64 I/O features) and up to 1,024 ESCON and 336
FICON channels (84 I/O features) on the Models E26, E40,
E56 and E64.
To increase the I/O device addressing capability, the I/O
subsystem provides support for multiple subchannels
sets (MSS), which are designed to allow improved device
connectivity for Parallel Access Volumes (PAVs). To sup-
port the highly scalable multi-book system design, the z10
EC I/O subsystem uses the Logical Channel Subsystem
(LCSS) which provides the capability to install up to 1024
CHPIDs across three I/O cages (256 per operating system
image). The Parallel Sysplex Coupling Link architecture
and technology continues to support high speed links pro-
viding efficient transmission between the Coupling Facility
and z/OS systems. HiperSockets provides high-speed
capability to communicate among virtual servers and logi-
cal partitions. HiperSockets is now improved with the IP
version 6 (IPv6) support; this is based on high-speed TCP/
IP memory speed transfers and provides value in allowing
applications running in one partition to communicate with
applications running in another without dependency on
an external network. Industry standard and openness are
design objectives for I/O in System z10 EC.
The z10 EC hardware model numbers (E12, E26, E40, E56
and E64) on their own do not indicate the number of PUs
which are being used as CPs. For software billing pur-
poses only, there will be a Capacity Identifier associated
with the number of PUs that are characterized as CPs. This

number will be reported by the Store System Information
(STSI) instruction for software billing purposes only. There
is no affinity between the hardware model and the number
of CPs. For example, it is possible to have a Model E26
which has 13 PUs characterized as CPs, so for software
billing purposes, the STSI instruction would report 713.
z10 EC Base and Sub-capacity Offerings
z10 EC model upgrades
There are full upgrades within the z10 EC models and
upgrades from any z9 EC or z990 to any z10 EC. Upgrade
of z10 EC Models E12, E26, E40 and E56 to the E64 is
disruptive. When upgrading to z10 EC Model E64, unlike
the z9 EC, the first book is retained. There are no direct
upgrades from the z9 BC or IBM eServer zSeries 900
(z900), or previous generation IBM eServer zSeries.
IBM is increasing the number of sub-capacity engines on
the z10 EC. A total of 36 sub-capacity settings are avail-
able on any hardware model for 1-12 CPs. Models with 13
CPs or greater must be full capacity.
• The z10 EC has 36 additional capacity settings at the low end
• Available on ANY H/W Model for 1 to 12 CPs. Models with 13
CPs or greater have to be full capacity
• All CPs must be the same capacity within the z10 EC
• All specialty engines run at full capacity. The one for one entitle-
ment to purchase one zAAP or one zIIP for each CP purchased
is the same for CPs of any capacity.
For the z10 EC models with 1-12 CPs, there are four
capacity settings per engine for central processors (CPs).
The entry point (Model 401) is approximately 23.69% of
a full speed CP (Model 701). All specialty engines con-
tinue to run at full speed. Sub-capacity processors have
availability of z10 EC features/functions and any-to-any
upgradeability is available within the sub-capacity matrix.
All CPs must be the same capacity setting size within one
z10 EC.
• Only 12 CPs can have granular capacity, other PUs must be
CBU or characterized as specialty engines
z10 EC Model Capacity Identifiers:
• 700, 401 to 412, 501 to 512, 601 to 612 and 701 to 764
• Capacity setting 700 does not have any CP engines
• Nxx, where n = the capacity setting of the engine, and
xx = the number of PU characterized as CPs in the CEC
•
Once xx exceeds 12, then all CP engines are full capacity

z10 EC Performance
The performance design of the z/Architecture can enable
the server to support a new standard of performance for
applications through expanding upon a balanced system
approach. As CMOS technology has been enhanced to
support not only additional processing power, but also
more PUs, the entire server is modified to support the
increase in processing power. The I/O subsystem supports
a greater amount of bandwidth than previous generations
through internal changes, providing for larger and faster
volume of data movement into and out of the server. Sup-
port of larger amounts of data within the server required
improved management of storage configurations, made
available through integration of the operating system and
hardware support of 64-bit addressing. The combined bal-
anced system design allows for increases in performance
across a broad spectrum of work.
may experience will vary depending upon considerations
such as the amount of multiprogramming in the user’s job
stream, the I/O configuration, and the workload processed.
LSPR workloads have been updated to reflect more
closely your current and growth workloads. The classifica-
tion Java Batch (CB-J) has been replaced with a new clas-
sification for Java Batch called ODE-B. The remainder of
the LSPR workloads are the same as those used for the z9
EC LSPR. The typical LPAR configuration table is used to
establish single-number-metrics such as MIPS and MSUs.
The z10 EC LSPR will rate all z/Architecture processors
running in LPAR mode, 64-bit mode, and assumes that
HiperDispatch is enabled.
For more detailed performance information, consult the
Large Systems Performance Reference (LSPR) available
Large System Performance Reference
IBM’s Large Systems Performance Reference (LSPR)
method is designed to provide comprehensive z/Archi-
tecture processor capacity ratios for different configura-
tions of Central Processors (CPs) across a wide variety
of system control programs and workload environments.
For z10 EC, z/Architecture processor capacity identifier is
defined with a (7XX) notation, where XX is the number of
installed CPs.
CPU Measurement Facility
The CPU Measurement Facility is a hardware facility which
consists of counters and samples. The facility provides a
means to collect run-time data for software performance
tuning. The detailed architecture information for this facility
™
can be found in the System z10 Library in Resource Link .
Based on using an LSPR mixed workload, the perfor-
mance of the z10 EC (2097) 701 is expected to be up to
1.62 times that of the z9 EC (2094) 701.
The LSPR contains the Internal Throughput Rate Ratios
(ITRRs) for the z10 EC and the previous-generation
zSeries processor families based upon measurements
and projections using standard IBM benchmarks in a con-
trolled environment. The actual throughput that any user

z10 EC I/O Subsystem
The z10 EC contains an I/O subsystem infrastructure
which uses an I/O cage that provides 28 I/O slots and
the ability to have one to three I/O cages delivering a
total of 84 I/O slots. ESCON, FICON Express4, FICON
Express2, FICON Express, OSA-Express3, OSA-Express2,
and Crypto Express2 features plug into the z10 EC I/O
cage along with any ISC-3s and InfiniBand Multiplexer
(IFB-MP) cards. All I/O features and their support cards
can be hot-plugged in the I/O cage. Installation of an I/O
cage remains a disruptive MES, so the Plan Ahead fea-
ture remains an important consideration when ordering a
z10 EC system. Each model ships with one I/O cage as
standard in the A-Frame (the A-Frame also contains the
Central Electronic Complex [CEC] cage where the books
reside) and any additional I/O cages are installed in the
Z-Frame. Each IFB-MP has a bandwidth up to 6 GigaBytes
per second (GB/sec) for I/O domains and MBA fanout
cards provide 2.0 GB/sec for ICB-4s.

from these many sources in one place. This will make it
much easier to manage I/O configurations, particularly
across multiple CPCs. The SIOA is a “view-only” tool. It
does not offer any options other than viewing options.
First the SIOA tool analyzes the current active IOCDS on
the SE. It extracts information about the defined channel,
partitions, link addresses and control units. Next the SIOA
tool asks the channels for their node ID information. The
FICON channels support remote node ID information, so
that is also collected from them. The data is then formatted
and displayed on five screens:
1)PCHID Control Unit Screen – Shows PCHIDs, CSS.
CHPIDs and their control units
2)PCHID Partition Screen – Shows PCHIDS, CSS. CHPIDs
and what partitions they are in
3)Control Unit Screen – Shows the control units, their
PCHIDs and their link addresses in each of the CSS’s
The z10 EC continues to support all of the features
announced with the System z9 EC such as:
4)Link Load Screen – Shows the Link address and the
PCHIDs that use it
• Logical Channel Subsystems (LCSSs) and support for
up to 60 logical partitions
5)Node ID Screen – Shows the Node ID data under the
PCHIDs
• Increased number of Subchannels (63.75k)
• Multiple Subchannel Sets (MSS)
The SIOA tool allows the user to sort on various columns
and export the data to a USB flash drive for later viewing.
• Redundant I/O Interconnect
• Physical Channel IDs (PCHIDs)
• System Initiated CHPID Reconfiguration
• Logical Channel SubSystem (LCSS) Spanning

length (LX) and short wavelength (SX). For customers
exploiting LX, there are two options available for unre-
peated distances of up to 4 kilometers (2.5 miles) or up
to 10 kilometers (6.2 miles). Both LX features use 9 micron
single mode fiber optic cables. The SX feature uses 50
or 62.5 micron multimode fiber optic cables. Each FICON
Express4 feature has four independent channels (ports)
and can be configured to carry native FICON traffic or Fibre
Channel (SCSI) traffic. LX and SX cannot be intermixed on
a single feature. The receiving devices must correspond to
the appropriate LX or SX feature. The maximum number of
FICON Express4 features is 84 using three I/O cages.
Fibre Channel Connectivity
The on demand operating environment requires fast data
access, continuous data availability, and improved flexibil-
ity, all with a lower cost of ownership. The four port FICON
Express4 and FICON Express2 features available on the
z9 EC continue to be supported on the System z10 EC.
Choose the FICON Express4 features that best meet
your business requirements.
FICON Express2 Channels
The z10 EC supports carrying forward up to 336 FICON
Express2 channels, each one operating at 1 or 2 Gb/sec
auto-negotiated. The FICON Express2 features are avail-
able in long wavelength (LX) using 9 micron single mode
fiber optic cables and short wavelength (SX) using 50 and
62.5 micron multimode fiber optic cables. Each FICON
Express2 feature has four independent channels (ports)
and each can be configured to carry native FICON traffic
or Fibre Channel (SCSI) traffic. LX and SX cannot be inter-
mixed on a single feature. The maximum number of FICON
Express2 features is 84, using three I/O cages.

Continued Support of Spanned Channels and Logical
Partitions
The System z10 EC Model E12 is limited to 64 features
– any combination of FICON Express4, FICON Express2
and FICON Express LX and SX features.
The FICON Express4 and FICON Express2, FICON and
FCP (CHPID types FC and FCP) channel types, can be
defined as a spanned channel and can be shared among
logical partitions within and across LCSSs.
The FICON Express4, FICON Express2 and FICON
Express feature conforms to the Fibre Connection (FICON)
architecture and the Fibre Channel (FC) architecture, pro-
viding connectivity between any combination of servers,
directors, switches, and devices in a Storage Area Network
(SAN). Each of the four independent channels (FICON
Express only supports two channels per feature) is capa-
ble of 1 Gigabit per second (Gb/sec), 2 Gb/sec, or 4
Gb/sec (only FICON Express4 supports 4 Gbps) depend-
ing upon the capability of the attached switch or device.
The link speed is auto-negotiated, point-to-point, and is
transparent to users and applications. Not all switches and
devices support 2 or 4 Gb/sec link data rates.
Modes of Operation
There are two modes of operation supported by FICON
Express4 and FICON Express2 SX and LX. These modes
are configured on a channel-by-channel basis – each of
the four channels can be configured in either of two sup-
ported modes.
• Fibre Channel (CHPID type FC), which is native FICON
or FICON Channel-to-Channel (server-to-server)
• Fibre Channel Protocol (CHPID type FCP), which sup-
ports attachment to SCSI devices via Fibre Channel
switches or directors in z/VM, z/VSE, and Linux on
System z10 environments
FICON Express4 and FICON Express2 Performance
Your enterprise may benefit from FICON Express4 and
FICON Express2 with:
Native FICON Channels
• Increased data transfer rates (bandwidth)
• Improved performance
Native FICON channels and devices can help to reduce
bandwidth constraints and channel contention to enable
easier server consolidation, new application growth,
large business intelligence queries and exploitation of On
Demand Business.
• Increased number of start I/Os
• Reduced backup windows
• Channel aggregation to help reduce infrastructure costs

The FICON Express4, FICON Express2 and FICON
Express channels support native FICON and FICON
Channel-to-Channel (CTC) traffic for attachment to serv-
ers, disks, tapes, and printers that comply with the FICON
architecture. Native FICON is supported by all of the z10
EC operating systems. Native FICON and FICON CTC are

Concurrent Update
The FICON Express4 SX and LX features may be added
to an existing z10 EC concurrently. This concurrent update
capability allows you to continue to run workloads through
other channels while the new FICON Express4 features are
being added. This applies to CHPID types FC and FCP.
Because the FICON CTC function is included as part of
the native FICON (FC) mode of operation, FICON CTC is
not limited to intersystem connectivity (as is the case with
ESCON), but will support multiple device definitions.

usage including install and IPL. Support for FCP devices
means that z10 EC servers are capable of attaching to
select FCP-attached SCSI devices and may access these
devices from Linux on z10 EC and z/VSE. This expanded
attachability means that enterprises have more choices
for new storage solutions, or may have the ability to use
existing storage devices, thus leveraging existing invest-
ments and lowering total cost of ownership for their Linux
implementations.
Native FICON (FC) channels support cascaded directors.
This support is for a single hop configuration only. Two-
director cascading requires a single vendor high integrity
fabric. Directors must be from the same vendor since cas-
caded architecture implementations can be unique. This
type of cascaded support is important for disaster recov-
ery and business continuity solutions because it can help
provide high availability, extended distance connectivity,

Switch Links) has the potential for fiber infrastructure cost
savings by reducing the number of channels for intercon-
necting the two sites.
The same FICON features used for native FICON chan-
nels can be defined to be used for Fibre Channel Protocol
(FCP) channels. FCP channels are defined as CHPID type
FCP. The 4 Gb/sec capability on the FICON Express4
channel means that 4 Gb/sec link data rates are available
for FCP channels as well.
FICON cascaded directors have the added value of high
integrity connectivity. Integrity features introduced within
the FICON Express channel and the FICON cascaded
switch fabric to aid in the detection and reporting of any
miscabling actions occurring within the fabric can prevent
data from being delivered to the wrong end point.
FCP – increased performance for small block sizes
The Fibre Channel Protocol (FCP) Licensed Internal
Code has been modified to help provide increased I/O
operations per second for small block sizes. With FICON
Express4, there may be up to 57,000 I/O operations
per second (all reads, all writes, or a mix of reads and
writes), an 80% increase compared to System z9. These
results are achieved in a laboratory environment using
one channel configured as CHPID type FCP with no other
processing occurring and do not represent actual field
measurements. A significant increase in I/O operations per
second for small block sizes can also be expected with
FICON Express2.
This FCP performance improvement is transparent to
operating systems that support FCP, and applies to all
the FICON Express4 and FICON Express2 features when
configured as CHPID type FCP, communicating with SCSI
devices.

SCSI IPL now a base function
The maximum number of I/Os is designed to be improved
up to 100% for small data transfers that can exploit zHPF.
Realistic production workloads with a mix of data transfer
sizes can see up to 30 to 70% of FICON I/Os utilizing zHPF
resulting in up to a 10 to 30% savings in channel utiliza-
tion. Sequential I/Os transferring less than a single track
size (for example, 12x4k bytes/IO) may also benefit.
The SCSI Initial Program Load (IPL) enablement feature,
first introduced on z990 in October of 2003, is no longer
required. The function is now delivered as a part of the
server Licensed Internal Code. SCSI IPL allows an IPL of
an operating system from an FCP-attached SCSI disk.
FCP Full fabric connectivity
The FICON Express4 and FICON Express2 features will
support both the existing FICON protocol and the zHPF
protocol concurrently in the server Licensed Internal Code.
High performance FICON is supported by z/OS for DB2,
VSAM, PDSE, and zFS applications. zHPF applies to all
FICON Express4 and FICON Express2 features (CHPID
type FC) and is exclusive to System z10. Exploitation is
required by the control unit.
FCP full fabric support means that any number of (single
vendor) FCP directors/ switches can be placed between
the server and an FCP/SCSI device, thereby allowing
many “hops” through a Storage Area Network (SAN) for
I/O connectivity. FCP full fabric connectivity enables mul-
tiple FCP switches/directors on a fabric to share links and
therefore provides improved utilization of inter-site con-
nected resources and infrastructure.
IBM System Storage DS8000 Release 4.1 delivers new
capabilities to support High Performance FICON for
System z, which can improve FICON I/O throughput on a
DS8000 port by up to 100%. The DS8000 series Licensed
Machine Code (LMC) level 5.4.2xx.xx (bundle version
64.2.xx.xx), or later, is required.
FICON and FCP for connectivity to disk, tape, and printers
High Performance FICON – improvement in performance and
RAS
Enhancements have been made to the z/Architecture
and the FICON interface architecture to deliver optimiza-
tions for online transaction processing (OLTP) workloads.
When exploited by the FICON channel, the z/OS operating
system, and the control unit, High Performance FICON for
System z (zHPF) is designed to help reduce overhead and
improve performance.
Platform and name server registration in FICON channel
The FICON channel now provides the same information
to the fabric as is commonly provided by open systems,
registering with the name server in the attached FICON
directors. With this information, your storage area net-
work (SAN) can be more easily and efficiently managed,
enhancing your ability to perform problem determination
and analysis.
Additionally, the changes to the architectures offer end-
to-end system enhancements to improve reliability, avail-
ability, and serviceability (RAS).
Registration allows other nodes and/or SAN managers to
query the name server to determine what is connected
to the fabric, what protocols are supported (FICON, FCP)
and to gain information about the System z10 using the
attributes that are registered. The FICON channel is now
designed to perform registration with the fibre channel’s
Management Service and Directory Service.
zHPF channel programs can be exploited by the OLTP I/O
workloads – DB2, VSAM, PDSE, and zFS – which transfer
small blocks of fixed size data (4K blocks). zHPF imple-
™
mentation by the IBM System Storage DS8000 is exclu-
sively for I/Os that transfer less than a single track of data.

• Platform’s:
The tool needs to know the FCP-specific I/O device defini-
tions in the form of a .csv file. This file can either be cre-
ated manually, or exported from Hardware Configuration
Definition/Hardware Configuration Manager (HCD/HCM).
The tool will then create the WWPN assignments, which
are required to set up your SAN. The tool will also create
a binary configuration file that can later on be imported by
your system.

Platform registration is a service defined in the Fibre Chan-
nel - Generic Services 4 (FC-GS-4) standard (INCITS
(ANSI) T11 group).
Extended distance FICON – improved performance at extended
distance
Platform and name server registration applies to all of the
FICON Express4, FICON Express2, and FICON Express
features (CHPID type FC). This support is exclusive to
System z10 and is transparent to operating systems.
An enhancement to the industry standard FICON architec-
ture (FC-SB-3) helps avoid degradation of performance at
extended distances by implementing a new protocol for
“persistent” Information Unit (IU) pacing. Control units that
exploit the enhancement to the architecture can increase
the pacing count (the number of IUs allowed to be in flight
from channel to control unit). Extended distance FICON also
allows the channel to “remember” the last pacing update for
use on subsequent operations to help avoid degradation of
performance at the start of each new operation.
Preplanning and setup of SAN for a System z10 environment
The worldwide port name (WWPN) prediction tool is now
available to assist you with preplanning of your Storage
Area Network (SAN) environment prior to the installation of
your System z10 server.
Improved IU pacing can help to optimize the utilization of
the link, for example help keep a 4 Gbps link fully utilized
at 50 km, and allows channel extenders to work at any dis-
tance, with performance results similar to that experienced
when using emulation.
This standalone tool is designed to allow you to setup
your SAN in advance, so that you can be up and running
much faster once the server is installed. The tool assigns
WWPNs to each virtual Fibre Channel Protocol (FCP)
channel/port using the same WWPN assignment algo-
rithms a system uses when assigning WWPNs for channels
utilizing N_Port Identifier Virtualization (NPIV).

The requirements for channel extension equipment are
simplified with the increased number of commands in
flight. This may benefit z/OS Global Mirror (Extended

sion kit is no longer required to simulate specific channel

reduce the complexity of physical FCP I/O connectivity.
Program Directed re-IPL
Program Directed re-IPL is designed to enable an operat-
ing system to determine how and from where it had been
loaded. Further, Program Directed re-IPL may then request
that it be reloaded again from the same load device using
the same load parameters. In this way, Program Directed
re-IPL allows a program running natively in a partition to
trigger a re-IPL. This re-IPL is supported for both SCSI
Extended distance FICON is transparent to operating sys-
tems and applies to all the FICON Express2 and FICON

rent pacing values when operating with control units that
cannot exploit extended distance FICON.
™
and ECKD devices. z/VM 5.3 provides support for guest
exploitation.
FICON Link Incident Reporting
FICON Link Incident Reporting is designed to allow an
operating system image (without operating intervention) to
register for link incident reports, which can improve the
ability to capture data for link error analysis. The informa-
tion can be displayed and is saved in the system log.
Exploitation of extended distance FICON is supported by
IBM System Storage DS8000 series Licensed Machine Code
(LMC) level 5.3.1xx.xx (bundle version 63.1.xx.xx), or later.
To support extended distance without performance deg-
radation, the buffer credits in the FICON director must be
set appropriately. The number of buffer credits required is
dependent upon the link data rate (1 Gbps, 2 Gbps, or 4
Gbps), the maximum number of buffer credits supported
by the FICON director or control unit, as well as application
and workload characteristics. High bandwidth at extended
distances is achievable only if enough buffer credits exist
to support the link data rate.
Serviceability Enhancements
Requests Node Identification Data (RNID) is designed to
facilitate the resolution of fiber optic cabling problems. You
can now request RNID data for a device attached to a
native FICON channel.
Local Area Network (LAN) connectivity –

Choose the OSA-Express3 features that best meet your
business requirements.
The above statements are based on OSA-Express3 perfor-
mance measurements performed in a laboratory environ-
ment on a System z10 and do not represent actual field
measurements. Results may vary.
To meet the demands of your applications, provide granu-
larity, facilitate redundant paths, and satisfy your infra-
structure requirements, there are five features from which
to choose. In the 10 GbE environment, Short Reach (SR) is
being offered for the first time.
Port density or granularity
The OSA-Express3 features have Peripheral Component
Interconnect Express (PCI-E) adapters. The previous table
identifies whether the feature has two or four ports for LAN
connectivity. Select the density that best meets your busi-
ness requirements. Doubling the port density on a single
feature helps to reduce the number of I/O slots required for
high-speed connectivity to the Local Area Network.

Short Reach (SR) using 50 or 62.5 micron multimode
fiber optic cabling. The connector is new; it is now the
small form factor, LC Duplex connector. Previously the SC
Duplex connector was supported for LR. The LC Duplex
connector is common with FICON, ISC-3, and OSA-
Express2 Gigabit Ethernet LX and SX.
Note that software PTFs or a new release may be required
(depending on CHPID type) to support all ports.
OSA-Express3 for reduced latency and improved throughput
To help reduce latency, the OSA-Express3 features now
have an Ethernet hardware data router; what was previ-
ously done in firmware (packet construction, inspection,
and routing) is now performed in hardware. With direct
memory access, packets flow directly from host memory
to the LAN without firmware intervention. OSA-Express3
is also designed to help reduce the round-trip networking
time between systems. Up to a 45% reduction in latency at
the TCP/IP application layer has been measured.
The OSA-Express3 features are exclusive to System z10.
There are operating system dependencies for exploitation
of two ports in OSD mode per PCI-E adapter. Whether it
is a 2-port or a 4-port feature, only one of the ports will be
visible on a PCI-E adapter if operating system exploitation
updates are not installed.
The OSA-Express3 features are also designed to improve
throughput for standard frames (1492 byte) and jumbo
frames (8992 byte) to help satisfy the bandwidth require-
ments of your applications. Up to a 4x improvement has
been measured (compared to OSA-Express2).
OSA-Express3 Ethernet features – Summary of benefits
OSA-Express3 10 GbE LR (single mode fiber), 10 GbE SR
(multimode fiber), GbE LX (single mode fiber), GbE SX
(multimode fiber), and 1000BASE-T (copper) are designed
for use in high-speed enterprise backbones, for local
area network connectivity between campuses, to connect
server farms to System z10, and to consolidate file servers

Medium Access Control (MAC) address.
– QDIO Layer 3 (Network or IP layer) – for IP workloads.
Packet forwarding decisions are based upon the IP
address. All guests share OSA’s MAC address.
• Jumbo frames in QDIO mode (8992 byte frame size)
when operating at 1 Gbps (fiber or copper) and 10 Gbps
(fiber).
The key benefits of OSA-Express3 compared to OSA-
Express2 are:
• 640 TCP/IP stacks per CHPID – for hosting more images.
• Reduced latency (up to 45% reduction) and increased
throughput (up to 4x) for applications
• Large send for IPv4 packets – for TCP/IP traffic and CPU
efficiency, offloading the TCP segmentation processing
from the host TCP/IP stack to the OSA-Express feature.
• More physical connectivity to service the network and
fewer required resources:
• Concurrent LIC update – to help minimize the disrup-
tion of network traffic during an update; when properly
configured, designed to avoid a configuration off or on
(applies to CHPID types OSD and OSN).
– Fewer CHPIDs to define and manage
– Reduction in the number of required I/O slots
– Possible reduction in the number of I/O drawers
– Double the port density of OSA-Express2
– A solution to the requirement for more than 48 LAN
ports (now up to 96 ports)
• Multiple Image Facility (MIF) and spanned channels – for
sharing OSA among logical channel subsystems

Activating all four ports on an OSA-Express3 feature pro-
vides you with more physical connectivity to service the
network and reduces the number of required resources (I/O

either a 10BASE-T (10 Mbps), 100BASE-TX (100 Mbps), or
1000BASE-T (1000 Mbps or 1 Gbps) Ethernet Local Area
Network (LAN). The feature supports auto-negotiation and
automatically adjusts to 10, 100, or 1000 Mbps, depending
upon the LAN. When the feature is set to autonegotiate,
the target device must also be set to autonegotiate. The
feature supports the following settings: 10 Mbps half or full

isolated (default) or isolated.
QDIO data connection isolation applies to the device
statement defined at the operating system level. While
an OSA-Express CHPID may be shared by an operating
system, the data device is not shared.
OSA-Express QDIO data connection isolation for the z/VM
environment
Multi-tier security zones are fast becoming the network
configuration standard for new workloads. Therefore, it is
essential for workloads (servers and clients) hosted in a
virtualized environment (shared resources) to be protected
from intrusion or exposure of data and processes from
other workloads.
QDIO data connection isolation applies to the z/VM 5.3 and
5.4 with PTFs environment and to all of the OSA-Express3
and OSA-Express2 features (CHPID type OSD) on System
z10 and to the OSA-Express2 features on System z9.
Network Traffic Analyzer
With Queued Direct Input/Output (QDIO) data connection
isolation you:
With the large volume and complexity of today’s network
traffic, the z10 EC offers systems programmers and
network administrators the ability to more easily solve
network problems. With the introduction of the OSA-
Express Network Traffic Analyzer and QDIO Diagnostic
Synchronization on the System z and available on the z10
EC, customers will have the ability to capture trace/trap
data and forward it to z/OS 1.8 tools for easier problem
determination and resolution.
• Have the ability to adhere to security and HIPAA-security
guidelines and regulations for network isolation between
the operating system instances sharing physical network
connectivity
• Can establish security zone boundaries that have been
defined by your network administrators
• Have a mechanism to isolate a QDIO data connec-
tion (on an OSA port), ensuring all internal OSA routing
between the isolated QDIO data connections and all
other sharing QDIO data connections is disabled. In this
state, only external communications to and from the iso-
lated QDIO data connection are allowed. If you choose
to deploy an external firewall to control the access
between hosts on an isolated virtual switch and sharing
LPARs then an external firewall needs to be configured
and each individual host and or LPAR must have a route
added to their TCP/IP stack to forward local traffic to the
firewall.
This function is designed to allow the operating system
to control the sniffer trace for the LAN and capture the
records into host memory and storage (file systems), using
existing host operating system tools to format, edit, and
process the sniffer records.
OSA-Express Network Traffic Analyzer is exclusive to the
z10 EC, z10 BC, z9 EC and z9 BC, and is applicable to the
OSA-Express3 and OSA-Express2 features when configured
as CHPID type OSD (QDIO), and is supported by z/OS.
Internal “routing” can be disabled on a per QDIO connec-
tion basis. This support does not affect the ability to share
an OSA-Express port. Sharing occurs as it does today, but
the ability to communicate between sharing QDIO data
connections may be restricted through the use of this sup-
port. You decide whether an operating system’s or z/VM’s
Dynamic LAN idle for z/OS
Dynamic LAN idle is designed to reduce latency and
improve network performance by dynamically adjusting
the inbound blocking algorithm. When enabled, the z/OS

For latency sensitive applications, the blocking algo-
rithm is modified to be “latency sensitive.” For streaming
(throughput sensitive) applications, the blocking algorithm
is adjusted to maximize throughput. The z/OS TCP/IP stack
can dynamically detect the application requirements,
making the necessary adjustments to the blocking algo-
rithm. The monitoring of the application and the blocking
algorithm adjustments are made in real-time, dynamically
adjusting the application’s LAN performance.
• Ability to dynamically add/remove OSA ports for “on
demand” bandwidth
• Full-duplex mode (send and receive)
• Target links for aggregation must be of the same type
(for example, Gigabit Ethernet to Gigabit Ethernet)
The Open Systems Adapter/Support Facility (OSA/SF) will
provide status information on an OSA port – its “shared” or
“exclusive use” state. OSA/SF is an integrated component
of z/VM.
System administrators can authorize the z/OS TCP/IP stack
to enable a dynamic setting, which was previously a static
setting. The z/OS TCP/IP stack is able to help determine
the best setting for the current running application, based
on system configuration, inbound workload volume, CPU
utilization, and traffic patterns.
Link aggregation is exclusive to System z10 and System
z9, is applicable to the OSA-Express3 and OSA-Express2
features in Layer 2 mode when configured as CHPID type
OSD (QDIO), and is supported by z/VM 5.3 and later.
Layer 2 transport mode:When would it be used?
If you have an environment with an abundance of Linux
images in a guest LAN environment, or you need to define
router guests to provide the connection between these guest
LANs and the OSA-Express3 features, then using the Layer
2 transport mode may be the solution. If you have Internet-
work Packet Exchange (IPX), NetBIOS, and SNA protocols,
in addition to Internet Protocol Version 4 (IPv4) and IPv6, use
of Layer 2 could provide “protocol independence.”
Link aggregation for z/VM in Layer 2 mode
z/VM Virtual Switch-controlled (VSWITCH-controlled) link
aggregation (IEEE 802.3ad) allows you to dedicate an
OSA-Express2 (or OSA-Express3) port to the z/VM operat-
ing system when the port is participating in an aggregated
group when configured in Layer 2 mode. Link aggregation
(trunking) is designed to allow you to combine multiple
physical OSA-Express3 and OSA-Express2 ports (of the
same type for example 1GbE or 10GbE) into a single logi-
cal link for increased throughput and for non-disruptive
failover in the event that a port becomes unavailable.
The OSA-Express3 features have the capability to perform
like Layer 2 type devices, providing the capability of being
protocol- or Layer-3-independent (that is, not IP-only).
With the Layer 2 interface, packet forwarding decisions
are based upon Link Layer (Layer 2) information, instead
of Network Layer (Layer 3) information. Each operating
system attached to the Layer 2 interface uses its own MAC
address. This means the traffic can be IPX, NetBIOS, SNA,
IPv4, or IPv6.
• Aggregated link viewed as one logical trunk and con-
taining all of the Virtual LANs (VLANs) required by the
LAN segment
• Load balance communications across several links in a
trunk to prevent a single link from being overrun
• Link aggregation between a VSWITCH and the physical
network switch
An OSA-Express3 feature can filter inbound datagrams by
Virtual Local Area Network identification (VLAN ID, IEEE
802.1q), and/or the Ethernet destination MAC address. Fil-
tering can reduce the amount of inbound traffic being pro-
cessed by the operating system, reducing CPU utilization.
• Point-to-point connections
• Up to eight OSA-Express3 or OSA-Express2 ports in one
aggregated link

Layer 2 transport mode is supported by z/VM and Linux on Hardware data router
System z.
With OSA-Express3, much of what was previously done in
firmware (packet construction, inspection, and routing) is
now performed in hardware. This allows packets to flow
directly from host memory to the LAN without firmware
intervention.
OSA Layer 3 Virtual MAC for z/OS
To simplify the infrastructure and to facilitate load balanc-
ing when an LPAR is sharing the same OSA Media Access
Control (MAC) address with another LPAR, each operating
system instance can now have its own unique “logical” or
“virtual” MAC (VMAC) address. All IP addresses associ-
ated with a TCP/IP stack are accessible using their own
VMAC address, instead of sharing the MAC address of
an OSA port. This applies to Layer 3 mode and to an OSA
port shared among Logical Channel Subsystems.
With the hardware data router, the “store and forward”
technique is no longer used, which enables true direct
memory access, a direct host memory-to-LAN flow, return-
ing CPU cycles for application use.
This avoids a “hop” and is designed to reduce latency and
to increase throughput for standard frames (1492 byte)
and jumbo frames (8992 byte).
This support is designed to:

IBM Communication Controller for Linux (CCL)
CCL is designed to help eliminate hardware dependen-
cies, such as 3745/3746 Communication Controllers,
ESCON channels, and Token Ring LANs, by providing a
software solution that allows the Network Control Program
(NCP) to be run in Linux on System z freeing up valuable
data center floor space.
• Dedicate a Layer 3 VMAC to a single TCP/IP stack
• Remove the dependency on Generic Routing Encapsu-
lation (GRE) tunnels
• Improve outbound routing
• Simplify configuration setup
• Allow WebSphere Application Server content-based
routing to work with z/OS in an IPv6 network
CCL helps preserve mission critical SNA functions, such
as SNI, and z/OS applications workloads which depend
upon these functions, allowing you to collapse SNA inside
a z10 EC while exploiting and leveraging IP.
• Allow z/OS to use a “standard” interface ID for IPv6
addresses
• Remove the need for PRIROUTER/SECROUTER function
in z/OS
The OSA-Express3 and OSA-Express2 GbE and
1000BASE-T Ethernet features provide support for CCL.
This support is designed to require no changes to operat-
ing systems (does require a PTF to support CHPID type
OSN) and also allows TPF to exploit CCL. Supported by
z/VM for Linux and z/TPF guest environments.
OSA Layer 3 VMAC for z/OS is exclusive to System z, and
is applicable to OSA-Express3 and OSA-Express2 features
when configured as CHPID type OSD (QDIO).
Direct Memory Access (DMA)
OSA-Express3 and the operating systems share a
common storage area for memory-to-memory communi-
cation, reducing system overhead and improving perfor-
mance. There are no read or write channel programs for
data exchange. For write processing, no I/O interrupts
have to be handled. For read processing, the number of
I/O interrupts is minimized.
OSA-Express3 and OSA-Express2 OSN (OSA for NCP)
OSA-Express for Network Control Program (NCP), Chan-
nel path identifier (CHPID) type OSN, is now available for
use with the OSA-Express3 GbE features as well as the
OSA-Express3 1000BASE-T Ethernet features.

ment is designed to allow seamless mixing of Layer 2 and
Layer 3 traffic, helping to reduce the total cost of network-
ing. Previously, Layer 2 and Layer 3 TCP/IP connections
through the same OSA port (CHPID) were unable to com-
municate with each other LPAR-to-LPAR using the Multiple
Image Facility (MIF).
OSA-Express for NCP is supported in the z/OS, z/VM,
z/VSE, TPF, z/TPF, and Linux on System z environments.
This enhancement is designed to facilitate a migration
from Layer 3 to Layer 2 and to continue to allow LAN
administrators to configure and manage their mainframe
network topology using the same techniques as their non-
mainframe topology.
OSA Integrated Console Controller
The OSA-Express Integrated Console Controller
(OSA-ICC) support is a no-charge function included in
Licensed Internal Code (LIC) on z10 EC, z10 BC, z9 EC,
z9 BC, z990, and z890 servers. It is available via the OSA-
Express3, OSA-Express2 and OSA-Express 1000BASE-
T Ethernet features, and supports Ethernet-attached
TN3270E consoles.
OSA/SF Virtual MAC and VLAN id Display Capability
The Open Systems Adapter/Support Facility (OSA/SF) has
the capability to support virtual Medium Access Control
(MAC) and Virtual Local Area Network (VLAN) identifica-
tions (IDs) associated with OSA-Express2 feature config-
ured as a Layer 2 interface. This information will now be
displayed as a part of an OSA Address Table (OAT) entry.
This information is independent of IPv4 and IPv6 formats.
There can be multiple Layer 2 VLAN Ids associated to a
single unit address. One group MAC can be associated to
multiple unit addresses.
The OSA-ICC provides a system console function at IPL
time and operating systems support for multiple logical
partitions. Console support can be used by z/OS, z/OS.e,
z/VM, z/VSE, z/TPF, and TPF. The OSA-ICC also supports
local non-SNA DFT 3270 and 328x printer emulation for

HiperSockets
The HiperSockets function, also known as internal Queued
Direct Input/Output (iDQIO) or internal QDIO, is an inte-
grated function of the z10 EC server that provides users
with attachments to up to sixteen high-speed “virtual”
Local Area Networks (LANs) with minimal system and
network overhead. HiperSockets eliminates the need to
utilize I/O subsystem operations and the need to traverse
an external network connection to communicate between
logical partitions in the same z10 EC server.
with Layer 2 and Layer 3 with Layer 3). A Layer 2 device
cannot communicate directly with a Layer 3 device in
another LPAR.
A HiperSockets device can filter inbound datagrams by
Virtual Local Area Network identification (VLAN ID, IEEE
802.1q), the Ethernet destination MAC address, or both.
Filtering can help reduce the amount of inbound traf-
fic being processed by the operating system, helping to
reduce CPU utilization.
Now, the HiperSockets internal networks on z10 EC can
support two transport modes: Layer 2 (Link Layer) as well
as the current Layer 3 (Network or IP Layer). Traffic can
be Internet Protocol (IP) version 4 or version 6 (IPv4, IPv6)
or non-IP (AppleTalk, DECnet, IPX, NetBIOS, or SNA).
HiperSockets devices are now protocol-independent and
Layer 3 independent. Each HiperSockets device has its
own Layer 2 Media Access Control (MAC) address, which
is designed to allow the use of applications that depend
on the existence of Layer 2 addresses such as DHCP
servers and firewalls.
Analogous to the respective Layer 3 functions, HiperSockets
Layer 2 devices can be configured as primary or secondary
connectors or multicast routers. This is designed to enable
the creation of high performance and high availability Link
Layer switches between the internal HiperSockets network
and an external Ethernet or to connect the HiperSockets
Layer 2 networks of different servers. The HiperSockets
Multiple Write Facility for z10 EC is also supported for
Layer 2 HiperSockets devices, thus allowing performance
improvements for large Layer 2 datastreams.
HiperSockets Layer 2 support is exclusive to System z10
and is supported by z/OS, Linux on System z environ-
ments, and z/VM for Linux guest exploitation.
Layer 2 support can help facilitate server consolidation.
Complexity can be reduced, network configuration is
simplified and intuitive, and LAN administrators can con-
figure and maintain the mainframe environment the same
as they do a non-mainframe environment. With support
of the new Layer 2 interface by HiperSockets, packet
forwarding decisions are now based upon Layer 2 infor-
mation, instead of Layer 3 information. The HiperSockets
device performs automatic MAC address generation and
assignment to allow uniqueness within and across logical
partitions (LPs) and servers. MAC addresses can also be
locally administered. The use of Group MAC addresses
for multicast is supported as well as broadcasts to all
other Layer 2 devices on the same HiperSockets network.
Datagrams are only delivered between HiperSockets
devices that are using the same transport mode (Layer 2
HiperSockets Multiple Write Facility for increased performance
Though HiperSockets provides high-speed internal TCP/IP
connectivity between logical partitions within a System z
server – the problem is that HiperSockets draws excessive
CPU utilization for large outbound messages. This may
lead to increased software licensing cost – HiperSock-
ets large outbound messages are charged to a general
CPU which can incur high general purpose CPU costs.
This may also lead to some performance issues due to
synchronous application blocking – HiperSockets large
outbound messages will block a sending application while
synchronously moving data.

A solution is HiperSockets Multiple Write Facility.
HiperSockets Enhancement for zIIP Exploitation
HiperSockets performance has been enhanced to allow
for the streaming of bulk data over a HiperSockets link
between logical partitions (LPARs). The receiving LPAR
can now process a much larger amount of data per I/O
In z/OS V1.10, specifically, the z/OS Communications
Server allows the HiperSockets Multiple Write Facility

from z/OS to be performed on a zIIP. The combination of

Facility, with fewer I/O interrupts, is designed to reduce
CPU utilization of the sending and receiving LPAR.
is described as “zIIP-Assisted HiperSockets for large mes-
sages.” zIIP-Assisted HiperSockets can help make highly
secure, available, virtual HiperSockets networking a more
attractive option. z/OS application workloads based on
XML, HTTP, SOAP, Java, etc., as well as traditional file
transfer, can benefit from zIIP enablement by helping to
lower general purpose processor utilization for such TCP/
IP traffic.
The HiperSockets Multiple Write solution moves multiple
output data buffers in one write operation.
If the function is disabled then one output data buffer
is moved in one write operation. This is also how
HiperSockets functioned in the past.
Only outbound z/OS TCP/IP large messages which origi-
nate within a z/OS host are eligible for HiperSockets zIIP-
Assisted processing. Other types of network traffic such
as IP forwarding, Sysplex Distributor, inbound processing,
small messages, or other non TCP/IP network protocols
are not eligible for zIIP-Assisted HiperSockets. When the
workload is eligible, then the TCP/IP HiperSockets device
driver layer (write) processing is redirected to a zIIP,
which will unblock the sending application. zIIP-Assisted
HiperSockets for large messages is available with z/OS
V1.10 with PTF and System z10 only. This feature is unsup-
ported if z/OS is running as a guest in a z/VM environment
and is supported for large outbound messages only.
If the function is enabled then multiple output data buf-
fers are moved in one write operation. This reduces CPU
utilization related to large outbound messages. When
enabled, HiperSockets Multiple Write will be used anytime
a message spans an IQD frame requiring multiple output
data buffers (SBALs) to transfer the message. Spanning
multiple output data buffers can be affected by a number
of factors including:
• IQD frame size
• Application socket send size
• TCP send size
• MTU size
To estimate potential offload, use PROJECTCPU for current
and existing workloads. This is accurate and very simple,
but you have to be on z/OS 1.10 with the enabling PTFs
AND System z10 server AND you need to be performing
HiperSockets Multiple Write workload already on z/OS.
The HiperSockets Multiple Write Facility is supported in
the z/OS environment. For a complete description of the
System z10 connectivity capabilities refer to IBM System z
Connectivity Handbook, SG24-5444.

z Can Do IT. The z10 processor chip has on board cryp-
tographic functions. Standard clear key integrated crypto-
graphic coprocessors provide high speed cryptography
for protecting data in storage. CP Assist for Cryptographic
Function (CPACF) supports DES, TDES, Secure Hash
Algorithms (SHA) for up to 512 bits, Advanced Encryption
Standard (AES) for up to 256 bits and Pseudo Random
Number Generation (PRNG). Logging has been added to
the TKE workstation to enable better problem tracking.
New integrated clear key encryption security features on
z10 EC include support for a higher advanced encryption
standard and more secure hashing algorithms. Performing
these functions in hardware is designed to contribute to
improved performance.
Enhancements to eliminate preplanning in the cryptogra-
phy area include the System z10 function to dynamically
add Crypto to a logical partition. Changes to image pro-
files, to support Crypto Express2 features, are available
without an outage to the logical partition. Crypto Express2
features can also be dynamically deleted or moved.
System z is investing in accelerators that provide improved
performance for specialized functions. The Crypto
Express2 feature for cryptography is an example. The
Crypto Express2 feature can be configured as a secure
key coprocessor or for Secure Sockets Layer (SSL) accel-
eration. The feature includes support for 13, 14, 15, 16, 17,
18 and 19 digit Personal Account Numbers for stronger
protection of data. And the tamper-resistant cryptographic
coprocessor is certified at FIPS 140-2 Level 4.
CP Assist for Cryptographic Function (CPACF)

• Is designed to support clear-key RSA operations
• Advanced Encryption Standard (AES) for 192-bit keys
and 256-bit keys
• Offloads compute-intensive RSA public-key and private-
key cryptographic operations employed in the SSL pro-
tocol Crypto Express2 features can be carried forward
on an upgrade to the System z10 EC, so users may con-
tinue to take advantage of the SSL performance and the
configuration capability.
• SHA-384 and SHA-512 bit for message digest
SHA-1, SHA-256, and SHA-512 are shipped enabled and
do not require the enablement feature.
Support for CPACF is also available using the Integrated
Cryptographic Service Facility (ICSF). ICSF is a com-
ponent of z/OS, and is designed to transparently use
the available cryptographic functions, whether CPACF
or Crypto Express2, to balance the workload and help
address the bandwidth requirements of your applications.
The configurable Crypto Express2 feature is supported by
z/OS, z/VM, z/VSE, and Linux on System z. z/VSE offers
support for clear-key operations only. Current versions of
z/OS, z/VM, and Linux on System z offer support for both
clear-key and secure-key operations.
Additional cryptographic functions and features with
Crypto Express2
The enhancements to CPACF are exclusive to the System
z10 and supported by z/OS, z/VM, z/VSE, and Linux on
System z.

Secure Key AES
Support for ISO 16609
The Advanced Encryption Standard (AES) is a National
Institute of Standards and Technology specification for the
encryption of electronic data. It is expected to become the
accepted means of encrypting digital information, includ-
ing financial, telecommunications, and government data.
Support for ISO 16609 CBC Mode T-DES Message
Authentication (MAC) requirements ISO 16609 CBC Mode
T-DES MAC is accessible through ICSF function calls
made in the PCI-X Cryptographic Adapter segment 3
Common Cryptographic Architecture (CCA) code.
AES is the symmetric algorithm of choice, instead of Data
Encryption Standard (DES) or Triple-DES, for the encryp-
tion and decryption of data. The AES encryption algorithm
will be supported with secure (encrypted) keys of 128,
192, and 256 bits. The secure key approach, similar to
what is supported today for DES and TDES, provides the
ability to keep the encryption keys protected at all times,
including the ability to import and export AES keys, using
RSA public key technology.
This is supported by z/OS and by z/VM for guest
exploitation.
Support for RSA keys up to 4096 bits
The RSA services in the CCA API are extended to sup-
port RSA keys with modulus lengths up to 4096 bits. The
services affected include key generation, RSA-based
key management, digital signatures, and other functions
related to these.
Support for AES encryption algorithm includes the master
key management functions required to load or generate
AES master keys, update those keys, and re-encipher key
tokens under a new master key.
Refer to the ICSF Application Programmers Guide, SA22-
7522, for additional details.
Cryptographic enhancements to Crypto Express2
Dynamically add crypto to a logical partition
Support for 13- thru 19-digit Personal Account Numbers
Credit card companies sometimes perform card security
code computations based on Personal Account Number
(PAN) data. Currently, ICSF callable services CSNBCSV
(VISA CVV Service Verify) and CSNBCSG (VISA CVV
Service Generate) are used to verify and to generate a
VISA Card Verification Value (CVV) or a MasterCard Card
Verification Code (CVC). The ICSF callable services cur-
rently support 13-, 16-, and 19-digit PAN data. To provide
additional flexibility, new keywords PAN-14, PAN-15, PAN-
17, and PAN-18 are implemented in the rule array for both
CSNBCSG and CSNBCSV to indicate that the PAN data is
comprised of 14, 15, 17, or 18 PAN digits, respectively.
Today, users can preplan the addition of Crypto Express2
features to a logical partition (LP) by using the Crypto page
in the image profile to define the Cryptographic Candidate
List, Cryptographic Online List, and Usage and Control
Domain Indexes in advance of crypto hardware installation.
With the change to dynamically add crypto to a logical
partition, changes to image profiles, to support Crypto
Express2 features, are available without outage to the
logical partition. Users can also dynamically delete or
move Crypto Express2 features. Preplanning is no longer
required.
This enhancement is supported by z/OS, z/VM for guest
exploitation, z/VSE, and Linux on System z.
Support for 13- through 19-digit PANs is exclusive to
System z10 and is offered by z/OS and z/VM for guest
exploitation.

Code (LIC) is loaded on the TKE workstation prior to ship-
ment. The TKE workstation offers security-rich local and
remote key management, providing authorized persons a
method of operational and master key entry, identification,
exchange, separation, and update. The TKE workstation
supports connectivity to an Ethernet Local Area Network
(LAN) operating at 10 or 100 Mbps. Up to ten TKE work-
stations can be ordered.
The Smart Card Reader, attached to a TKE workstation
with the 5.3 level of LIC will support System z10 BC, z10
EC, z9 EC, and z9 BC. However, TKE workstations with 5.0,
5.1 and 5.2 LIC must be upgraded to TKE 5.3 LIC.
TKE additional smart cards
You have the capability to order Java-based blank smart
cards which offers a highly efficient cryptographic and
data management application built-in to read-only memory
for storage of keys, certificates, passwords, applications,
and data. The TKE blank smart cards are compliant with
FIPS 140-2 Level 2. When you place an order for a quantity
of one, you are shipped 10 smart cards.
Enhancement with TKE 5.3 LIC
The TKE 5.3 level of LIC includes support for the AES
encryption algorithm, adds 256-bit master keys, and
includes the master key management functions required to
load or generate AES master keys to cryptographic copro-
cessors in the host.
Also included is an imbedded screen capture utility to
permit users to create and to transfer TKE master key entry
instructions to diskette or DVD. Under ‘Service Manage-
ment’ a “Manage Print Screen Files” utility will be available

Improved Key Exchange With Non-CCA Cryptographic
Systems
Remote Loading of Initial ATM Keys
Typically, a new ATM has none of the financial institution’s
keys installed. Remote Key Loading refers to the pro-
cess of loading Data Encryption Standard (DES) keys to
Automated Teller Machines (ATMs) from a central admin-
istrative site without the need for personnel to visit each
machine to manually load DES keys. This has been done
by manually loading each of the two clear text key parts
individually and separately into ATMs. Manual entry of
keys is one of the most error-prone and labor-intensive
activities that occur during an installation, making it expen-
sive for the banks and financial institutions.
IBM Common Cryptographic Architecture (CCA) employs
Control Vectors to control usage of cryptographic keys.
Non-CCA systems use other mechanisms, or may use
keys that have no associated control information. This
enhancement provides the ability to exchange keys
between CCA systems, and systems that do not use Con-
trol Vectors. Additionally, it allows the CCA system owner
to define permitted types of key import and export which
can help to prevent uncontrolled key exchange that can
open the system to an increased threat of attack.
These enhancements are exclusive to System z10, and
System z9 and are supported by z/OS and z/VM for z/OS
guest exploitation.
Remote Key Loading Benefits
• Provides a mechanism to load initial ATM keys without
the need to send technical staff to ATMs
• Reduces downtime due to key entry errors
• Reduces service call and key management costs
• Improves the ability to manage ATM conversions and
upgrades
Integrated Cryptographic Service Facility (ICSF), together
with Crypto Express2, support the basic mechanisms in
Remote Key Loading. The implementation offers a secure
bridge between the highly secure Common Cryptographic
Architecture (CCA) environment and the various formats
and encryption schemes offered by the ATM vendors. The
following ICSF services are offered for Remote Key loading:
• Trusted Block Create (CSNDTBC) This callable service
is used to create a trusted block containing a public key
and some processing rules.
• Remote Key Export (CSNDRKX) This callable service
uses the trusted block to generate or export DES keys
for local use and for distribution to an ATM or other
remote device.

• The number of temporary records that can be installed
on the Central Processor Complex (CPC) has increased
from four to eight.
Just-in-time deployment of System z10 EC Capacity on
Demand (CoD) is a radical departure from previous System
z and zSeries servers. This new architecture allows:
• Resource tokens are now available for On/Off CoD.
• Up to eight temporary records to be installed on the
CPC and active at any given time
The z10 EC also introduces a architectural approach for
temporary offerings that can change the thinking about on
demand capacity. One or more flexible configuration defini-
tions can be used to solve multiple temporary situations and
multiple capacity configurations can be active at once (for
example, activation of just two CBUs out of a definition that
has four CBUs is acceptable). This means that On/Off CoD
can be active and up to seven other offerings can be active
simultaneously. Tokens can be purchased for On/Off CoD
so hardware activations can be prepaid.
• Up to 200 temporary records to be staged on the SE
• Variability in the amount of resources that can be acti-
vated per record
• The ability to control and update records independent
of each other
• Improved query functions to monitor the state of each
record
• The ability to add capabilities to individual records con-
currently, eliminating the need for constant ordering of
new temporary records for different user scenarios
All activations can be done without having to interact with
IBM—when it is determined that capacity is required,
no passwords or phone connections are necessary. As
long as the total z10 EC can support the maximums that
are defined, then they can be made available. With the
z10 EC, it is now possible to add permanent capacity
while a temporary capacity is currently activated, without
having to return first to the original configuration.
• Permanent LIC-CC upgrades to be performed while
temporary resources are active
These capabilities allow you to access and manage
processing capacity on a temporary basis, providing
increased flexibility for on demand environments. The CoD
offerings are built from a common Licensed Internal Code
– Configuration Code (LIC-CC) record structure. These
Temporary Entitlement Records (TERs) contain the infor-
mation necessary to control which type of resource can be
accessed and to what extent, how many times and for how
long, and under what condition – test or real workload.
Use of this information gives the different offerings their
personality.
Capacity on Demand – Temporary Capacity:
The set of contract documents which support the various
Capacity on Demand offerings available for z10 EC has
been completely refreshed. While customers with exist-

Capacity Back Up (CBU): Temporary access to dormant
processing units (PUs), intended to replace capacity lost
within the enterprise due to a disaster. CP capacity or any
and all specialty engine types (zIIP, zAAP, SAP, IFL, ICF)
can be added up to what the physical hardware model
can contain for up to 10 days for a test activation or 90
days for a true disaster recovery.
While all new CBU contract documents contain the new
CBU Test terms, existing CBU customers will need to exe-
cute a contract to expand their authorization for CBU Test
upgrades if they want to have the right to execute produc-
tion workload on the CBU Upgrade during a CBU Test.
Amendment for CBU Tests
The modification of CBU Test terms is available for existing
CBU customers via the IBM Customer Agreement Amend-
ment for IBM System z Capacity Backup Upgrade Tests (in
the US this is form number Z125-8145). This amendment
can be executed at any time, and separate from any par-
ticular order.
On system z10 the CBU entitlement records contain an
expiration date that is established at the time of order
and is dependent upon the quantity of CBU years. You
will now have the capability to extend your CBU entitle-
ments through the purchase of additional CBU years. The
number of CBU years per instance of CBU entitlement
remains limited to five and fractional years are rounded up
to the near whole integer when calculating this limit. For
instance, if there are two years and eight months to the
expiration date at the time of order, the expiration date can
be extended by no more than two additional years. One
test activation is provided for each additional CBU year
added to the CBU entitlement record.
Capacity for Planned Event (CPE): Temporary access
to dormant PUs, intended to replace capacity lost within
the enterprise due to a planned event such as a facility
upgrade or system relocation. This offering is available
only on the System z10. CPE is similar to CBU in that it is
intended to replace lost capacity; however, it differs in its
scope and intent. Where CBU addresses disaster recovery
scenarios that can take up to three months to remedy, CPE
is intended for short-duration events lasting up to three
days, maximum. Each CPE record, once activated, gives
you access to all dormant PUs on the machine that can be
configured in any combination of CP capacity or specialty
engine types (zIIP, zAAP, SAP, IFL, ICF).
CBU Tests: The allocation of the default number of test
activations changed. Rather than a fixed default number
of five test activations for each CBU entitlement record,
the number of test activations per instance of the CBU
entitlement record will coincide with the number of CBU
years, the number of years assigned to the CBU record.
This equates to one test activation per year for each CBU
entitlement purchased.
On/Off Capacity on Demand (On/Off CoD): Temporary
access to dormant PUs, intended to augment the existing
capacity of a given system. On/Off CoD helps you contain
workload spikes that may exceed permanent capacity
such that Service Level Agreements cannot be met and
business conditions do not justify a permanent upgrade.
An On/Off CoD record allows you to temporarily add CP
capacity or any and all specialty engine types (zIIP, zAAP,
SAP, IFL, ICF) up to the following limits:
These changes apply only to System z10 and to CBU
entitlements purchased through the IBM sales channel or
directly from Resource Link.
There are now terms governing System z Capacity Back
Up (CBU) which allow customers to execute production
workload on a CBU Upgrade during a CBU Test..
• The quantity of temporary CP capacity ordered is limited
by the quantity of purchased CP capacity (permanently
active plus unassigned).
40

• The quantity of temporary IFLs ordered is limited by
quantity of purchased IFLs (permanently active plus
unassigned).
how many tokens go into each pool. Once On/Off CoD
resources are activated, tokens will be decremented from
their pools every 24 hours. The amount decremented is
based on the highest activation level for that engine type
during the previous 24 hours.
• Temporary use of unassigned CP capacity or unas-
signed IFLs will not incur a hardware charge.
• The quantity of permanent zIIPs plus temporary zIIPs
can not exceed the quantity of purchased (permanent
plus unassigned) CPs plus temporary CPs and the
quantity of temporary zIIPs can not exceed the quantity
of permanent zIIPs.
Resource tokens are intended to help customers bound
the hardware costs associated with using On/Off CoD. The
use of resource tokens is optional and they are available
on either a prepaid or post-paid basis. When prepaid, the
customer is billed for the total amount of resource tokens
contained within the On/Off CoD record. When post-paid,
the total billing against the On/Off Cod record is limited by
the total amount of resource tokens contained within the
record. Resource Link will provide the customer an order-
ing wizard to help determine how many tokens they need
to purchase for different activation scenarios. Resource
tokens within an On/Off CoD record may also be replen-
ished.
• The quantity of permanent zAAPs plus temporary zAAPs
can not exceed the quantity of purchased (permanent
plus unassigned) CPs plus temporary CPs and the
quantity of temporary zAAPs can not exceed the quan-
tity of permanent zAAPs.
•
The quantity of temporary ICFs ordered is limited by the
quantity of permanent ICFs as long as the sum of perma-
nent and temporary ICFs is less than or equal to 16.
•
The quantity of temporary SAPs ordered is limited by the
quantity of permanent SAPs as long as the sum of perma-
nent and temporary SAPs is less than or equal to 32.
Resource Link offers an ordering wizard to help determine
how many tokens you need to purchase for different acti-
vation scenarios. Resource tokens within an On/Off CoD
record may also be replenished. For more information
on the use and ordering of resource tokens, refer to the
Capacity on Demand Users Guide, SC28-6871.
Although the System z10 E will allow up to eight temporary
records of any type to be installed, only one temporary On/
Off CoD record may be active at any given time. An On/Off
CoD record may be active while other temporary records
are active.
Capacity Provisioning
Management of temporary capacity through On/Off CoD
is further enhanced through the introduction of resource
tokens. For CP capacity, a resource token represents
an amount of processing capacity that will result in one
MSU of SW cost for one day – an MSU-day. For specialty
engines, a resource token represents activation of one
engine of that type for one day – an IFL-day, a zIIP-day or
a zAAP-day. The different resource tokens are contained
in separate pools within the On/Off CoD record. The cus-
tomer, via the Resource Link ordering process, determines
Hardware working with software is critical. The activation
of On/Off CoD on z10 EC can be simplified or automated
by using z/OS Capacity Provisioning (available with z/OS
V1.10 and z/OS V1.9). This capability enables the monitor-
ing of multiple systems based on Capacity Provisioning and
Workload Manager (WLM) definitions. When the defined
conditions are met, z/OS can suggest capacity changes for
manual activation from a z/OS console or the system can
add or remove temporary capacity automatically and with-
out operator intervention. z10 EC can do IT better.

z/OS Capacity provisioning allows you to set up rules
defining the circumstances under which additional capac-
ity should be provisioned in order to fulfill a specific busi-
ness need. The rules are based on criteria, such as: a
specific application, the maximum additional capacity that
should be activated, time and workload conditions. This
support provides a fast response to capacity changes and
ensures sufficient processing power will be available with
the least possible delay even if workloads fluctuate.
Capacity on Demand – Permanent Capacity
Customer Initiated Upgrade (CIU) facility: When your
business needs additional capacity quickly, Customer
Initiated Upgrade (CIU) is designed to deliver it. CIU is
designed to allow you to respond to sudden increased
capacity requirements by requesting a System z10 EC PU
and/or memory upgrade via the Web, using IBM Resource
Link, and downloading and applying it to your System z10
EC server using your system’s Remote Support connec-
tion. Further, with the Express option on CIU, an upgrade
may be made available for installation as fast as within a
few hours after order submission.
An installed On/Off CoD record is a necessary prerequisite
for automated control of temporary capacity through z/OS
Capacity Provisioning.
Permanent upgrades: Orders (MESs) of all PU types and
memory for System z10 EC servers that can be delivered
by Licensed Internal Code, Control Code (LIC-CC) are
eligible for CIU delivery. CIU upgrades may be performed
up to the maximum available processor and memory
resources on the installed server, as configured. While
capacity upgrades to the server itself are concurrent,
your software may not be able to take advantage of the
increased capacity without performing an Initial Program-
ming Load (IPL).
See z/OS MVS Capacity Provisioning User’s Guide
(SA33-8299) for more information.
On/Off CoD Test: On/Off CoD allows for a no-charge test.
No IBM charges are assessed for the test, including IBM
charges associated with temporary hardware capacity,
IBM software, or IBM maintenance. This test can be used
to validate the processes to download, stage, install, acti-
vate, and deactivate On/Off CoD capacity non-disruptively.
Each On/Off CoD-enabled server is entitled to only one no-
charge test. This test may last up to a maximum duration
of 24 hours commencing upon the activation of any capac-
ity resources contained in the On/Off CoD record. Activa-
tion levels of capacity may change during the 24 hour test
period. The On/Off CoD test automatically terminates at
the end of the 24 hours period. In addition to validating
the On/Off CoD function within your environment, you may
choose to use this test as a training session for your per-
sonnel who are authorized to activate On/Off CoD.

Reliability, Availability, and Serviceability
(RAS)
In today’s on demand environment, downtime is not only
unwelcome—it’s costly. If your applications aren’t consis-
tently available, your business suffers. The damage can
extend well beyond the financial realm into key areas of
customer loyalty, market competitiveness and regulatory
compliance. High on the list of critical business require-
ments today is the need to keep applications up and run-
ning in the event of planned or unplanned disruptions to
your systems.
RAS Design Focus
High Availability (HA) – The attribute of a system
designed to provide service during defined peri-
ods, at acceptable or agreed upon levels and masks
UNPLANNED OUTAGES from end users. It employs fault
tolerance, automated failure detection, recovery, bypass
reconfiguration, testing, problem and change manage-
ment.
Continuous Operations (CO) – The attribute of a system
designed to continuously operate and mask PLANNED
OUTAGES from end users. It employs non-disruptive hard-
ware and software changes, non-disruptive configuration
and software coexistence.
While some servers are thought of offering weeks or even
months of up time, System z thinks of this in terms of
achieving years. The z10 EC continues our commitment
to deliver improvements in hardware Reliability, Availability
and Serviceability (RAS) with every new System z server.
They include microcode driver enhancements, dynamic
segment sparing for memory and fixed HSA. The z10 EC
is a server that can help keep applications up and running
in the event of planned or unplanned disruptions to the
system.
Continuous Availability (CA) – The attribute of a system
designed to deliver non-disruptive service to the end user
7 days a week, 24 HOURS A DAY (there are no planned or
unplanned outages). It includes the ability to recover from
a site disaster by switching computing to a second site.
The System z10 EC is designed to deliver industry lead-
ing reliability, availability and security our customers have
come to expect from System z servers. System z10 EC
RAS is designed to reduce all sources of outages by
reducing unscheduled, scheduled and planned outages.
Planned outages are further designed to be reduced
with the introduction of concurrent I/O drawer add and
eliminating pre-planning requirements. These features are
designed to reduce the need for a Power-on-Reset (POR)
and help eliminate the need to deactivate/activate/IPL a
logical partition.

Availability Functions
With the z10 EC, significant steps have been taken in the
area of server availability with a focus on reducing pre-
Enhanced Book Availability
With proper planning, z10 EC is designed to allow a
planning requirements. Pre-planning requirements are min- single book, in a multi-book server, to be non-disrup-
imized by delivering and reserving 16 GB for HSA so the
maximum configuration capabilities can be exploited. And
with the introduction of the ability to seamlessly include
such events as creation of LPARs, inclusion of logical
subsystems, changing logical processor definitions in an
LPAR, and the introduction of cryptography into an LPAR.
Features that carry forward from previous generation pro-
cessors include the ability to dynamically enable I/O, and
the dynamic swapping of processor types.
tively removed from the server and re-installed during an
upgrade or repair action. To minimize the effect on current
workloads and applications, you should ensure that you
have sufficient inactive physical resources on the remain-
ing books to complete a book removal.
For customers configuring for maximum availability we rec-
ommend to purchasing models with one additional book.
To ensure you have the appropriate level of memory, you
may want to consider the selection of the Flexible Memory
Option features to provide additional resources when
completing an Enhanced Book Availability action or when
considering plan ahead options for the future. Enhanced
Book Availability may also provide benefits should you
choose not to configure for maximum availability. In these
cases, you should have sufficient inactive resources on
the remaining books to contain critical workloads while
completing a book replacement. Contact your IBM rep-
resentative to help you determine and plan the proper
configuration to support your workloads when using non-
disruptive book maintenance.
Hardware System Area (HSA)
Fixed HSA of 16 GB is provided as standard with the z10
EC. The HSA has been designed to eliminate planning for
HSA. Preplanning for HSA expansion for configurations will
be eliminated as HCD/IOCP will, via the IOCDS process,
always reserve:
• 4 Logical Channel Subsystems (LCSS), pre-defined
• 60 Logical Partitions (LPARs), pre-defined
• Subchannel set 0 with 63.75k devices
• Subchannel set 1 with 64K-1 devices
Enhanced Book Availability is an extension of the support
for Concurrent Book Add (CBA) delivered on z990. CBA
makes it possible to concurrently upgrade a server by
integrating a second, third, or fourth book into the server
without necessarily affecting application processing. The
following scenarios prior to the availability of EBA would
require a disruptive customer outage. With EBA these
upgrade and repair procedures can be performed concur-
rently without interfering with customer operations.
• Dynamic I/O Reconfiguration – always enabled by
default
• Concurrent Patch - always enabled by default
• Add/Change the number of logical CP, IFL, ICF, zAAP,
zIIP, processors per partition and add SAPs to the con-
figuration
• Dynamic LPAR PU assignment optimization CPs, ICFs,
IFLs, zAAPs, zIIPs, SAPs
• Dynamically Add/Remove Crypto (no LPAR deactivation
required)

Concurrent Physical Memory Upgrade
ment of an HCA2-C fanout card or book, the z10 EC is
designed to provide access to your I/O devices through
another InfiniBand Multiplexer (IFB-MP) to the affected I/O
domains. This is exclusive to System z10 EC and z9 EC.
Allows one or more physical memory cards on a single
book to be added, or an existing card to be upgraded
increasing the amount of physical memory in the system.
Concurrent Physical Memory Replacement
Allows one or more defective memory cards on a single
book to be replaced concurrent with the operation of the
system.
Enhanced Driver Maintenance
One of the greatest contributors to downtime during
planned outages is Licensed Internal Code (LIC) updates.
When properly configured, z10 EC is designed to permit
select planned LIC updates.
Concurrent Defective Book Replacement
A new query function has been added to validate LIC EDM
requirements in advance. Enhanced programmatic internal
controls have been added to help eliminate manual analy-
sis by the service team of certain exception conditions.
Allows the concurrent repair of a defective book when that
book is operating degraded due to errors such as multiple
defective processors.
Enhanced Book Availability is exclusive to z10 EC and
z9 EC.
With the z10 EC, PR/SM code has been enhanced to allow
multiple EDM ‘From’ sync points. Automatic apply of EDM
licensed internal change requirements is now limited to EDM
and the licensed internal code changes update process.
Flexible Memory Option
Flexible memory was first introduced on the z9 EC as part
of the design changes and offerings to support enhanced
book availability. Flexible memory provides the additional
resources to maintain a constant level of memory when
replacing a book. On z10 EC, the additional resources
required for the flexible memory configurations are
provided through the purchase of preplanned memory fea-
tures along with the purchase of your memory entitlement.
In most cases, this implementation provides a lower-cost
solution compared to z9 EC. Flexible memory configura-
tions are available on Models E26, E40, E56, and E64 only
and range from 32 GB to 1136 GB, model dependent.
There are several reliability, availability, and serviceability
(RAS) enhancements that have been made to the HMC/SE
based on the feedback from the System z9 Enhanced
Driver Maintenance field experience.
• Change to better handle intermittent customer network
issues
• EDM performance improvements
• New EDM user interface features to allow for customer
and service personnel to better plan for the EDM
• A new option to check all licensed internal code which
can be executed in advance of the EDM preload or
activate
Redundant I/O Interconnect
z10 EC with Redundant I/O Interconnect is designed to
allow you to replace a book or respond to a book failure
and retain connectivity to resources. In the event of a
failure or customer initiated action such as the replace-
Dynamic Oscillator Switchover
The z10 EC has two oscillator cards, a primary and a
backup. For most cases, should a failure occur on the pri-
mary oscillator card, the backup can detect it, switch over,

and provide the clock signal to the system transparently,
with no system outage. Previously, in the event of a failure
of the active oscillator, a system outage would occur, the
subsequent system Power On Reset (POR) would select
the backup, and the system would resume operation.
Dynamic Oscillator Switchover is exclusive to System z10
EC and System z9.
Auto-Switchover for Support Element (SE): The z10
EC has two Support Elements. In the event of failure on
the Primary SE, the switchover to the backup is handled
automatically. There is no need for any intervention by the
Customer or Service Representative.
Concurrent Memory Upgrade
This function allows adding memory concurrently, up to
the maximum amount physically installed. In addition,
the Enhanced Book Availability function also enables a
memory upgrade to an installed z10 EC book in a multi-
book server.
Transparent Sparing
The z10 EC offers two PUs reserved as spares per server.
In the case of processor failure, these spares are used
for transparent sparing. On z10 EC sparing happens on
a core granularity rather than chip granularity as on z990
and System z9 (for which “chip” equaled “2 cores”).
Plan Ahead Memory
Future memory upgrades can now be preplanned to be
non-disruptive. The preplanned memory feature will add
the necessary physical memory required to support target
memory sizes. The granularity of physical memory in the
System z10 design is more closely associated with the
granularity of logical, entitled memory, leaving little room
for growth. If you anticipate an increase in memory require-
ments, a “target” logical memory size can now be speci-
fied in the configuration tool along with a “starting” logical
memory size. The configuration tool will then calculate the
physical memory required to satisfy this target memory.
Should additional physical memory be required, it will be
fulfilled with the currently available preplanned memory
features.
Concurrent Maintenance
Concurrent Service for I/O features: All the features that
plug into the I/O Cage are able to be added and replaced
concurrent with system operation. This virtually eliminates
any need to schedule outage for service to upgrade the
I/O subsystem on this cage.
Upgrade for Coupling Links: z10 EC has concurrent
maintenance for the ISC-3 daughter card. Also, Coupling
Links can be added concurrently. This eliminates a need
for scheduled downtime in the demanding sysplex envi-
ronment.
Cryptographic feature: The Crypto Express2 feature
plugs in the I/O cage and can be added or replaced con-
currently with system operation.
The preplanned memory feature is offered in 16 gigabyte
(GB) increments. The quantity assigned by the configu-
ration tool is the number of 16 GB blocks necessary to
increase the physical memory from that required for the
“starting” logical memory to the physical memory required
for the “target” logical configuration. Activation of any pre-
planned memory requires the purchase of a preplanned
Redundant Cage Controllers: The Power and Service
Control Network features redundant Cage Controllers for
Logic and Power control. This design enables non-disrup-
tive service to the controllers and virtually eliminates cus-
tomer scheduled outage.

risen and utilities have restricted the amount of power
usage, it is important to review the role of the server in bal-
ancing IT spending.
Plan ahead memory is exclusive to System z10 and is
transparent to operating systems.
Power Monitoring
The “mainframe gas gauge” feature introduced on the
System z9 servers, provides power and thermal informa-
tion via the System Activity Display (SAD) on the Hardware
Management Console and will be available on the z10
EC giving a point in time reference of the information. The
current total power consumption in watts and BTU/hour as
well as the air input temperature will be displayed.
Service Enhancements
z10 EC service enhancements designed to avoid sched-
uled outages include:
• Concurrent firmware fixes
• Concurrent driver upgrades
• Concurrent parts replacement
• Concurrent hardware upgrades
• DIMM FRU indicators
Power Estimation Tool
To assist in energy planning, Resource Link provides tools
to estimate server energy requirements before a new
server purchase. A user will input the machine model,
memory, and I/O configuration and the tool will output
an estimate of the system total heat load and utility input
power. A customized planning aid is also available on
Resource Link which provides physical characteristics
of the machine along with cooling recommendations,
environmental specifications, system power rating, power
plugs/receptacles, line cord wire specifications and the
machine configuration.

Parallel Sysplex Cluster Technology
IBM Systems Director Active Energy Manager
Parallel Sysplex clustering is designed to bring the power
of parallel processing to business-critical System z10,
System z9, z990 or z890 applications. A Parallel Sysplex
cluster consists of up to 32 z/OS images coupled to one or
more Coupling Facilities (CFs or ICFs) using high-speed
specialized links for communication. The Coupling Facili-
ties, at the heart of the Parallel Sysplex cluster, enable
high speed, read/ write data sharing and resource sharing
among all the z/OS images in a cluster. All images are also

IBM Systems Director Active Energy Manager (AEM) is a
building block which enables customers to manage actual

ers place in the data center. The z10 EC provides support
for IBM Systems Director Active Energy Manager (AEM)
for Linux on System z for a single view of actual energy
usage across multiple heterogeneous IBM platforms within
the infrastructure. AEM for Linux on System z will allow
tracking of trends for both the z10 EC as well as multiple
server platforms. With this trend analysis, a data center
administrator will have the data to help properly estimate
power inputs and more accurately plan data center con-
solidation or modification projects.

connected to a Sysplex Timer or by implementing the
Server Time Protocol (STP), so that all events can be prop-
erly sequenced in time.
On System z10, the HMC will now provide support for the
Active Energy Manager (AEM) which will display power
consumption/air input temperature as well as exhaust
temperature. AEM will also provide some limited status
configuration information which might assist in explaining
changes to the power consumption. AEM is exclusive to
System z10.
IBM System z servers stand alone against competition and
have stood the test of time with our business resiliency
solutions. Our coupling solutions with Parallel Sysplex
technology allow for greater scalability and availability.
Parallel Sysplex Resource Sharing enables multiple
system resources to be managed as a single logical
resource shared among all of the images. Some examples
of resource sharing include JES2 Checkpoint, GRS “star,”
and Enhanced Catalog Sharing; all of which provide sim-
plified systems management, increased performance and/
or scalability.
Although there is significant value in a single footprint and
multi-footprint environment with resource sharing, those
customers looking for high availability must move on to
a database data sharing configuration. With the Paral-
lel Sysplex environment, combined with the Workload
Manager and CICS TS, DB2 or IMS, incoming work can

List notification improvements: Prior to CFCC Level 16,
when a shared queue (subsidiary list) changed state from
empty to non-empty, the CF would notify ALL active con-
nectors. The first one to respond would process the new
message, but when the others tried to do the same, they
would find nothing, incurring additional overhead.
be dynamically routed to the z/OS image most capable of
handling the work. This dynamic workload balancing, along
with the capability to have read/write access data from any-
where in the Parallel Sysplex cluster, provides scalability
and availability. When configured properly, a Parallel Sys-
plex cluster is designed with no single point of failure and
can provide customers with near continuous application
availability over planned and unplanned outages.
CFCC Level 16 can help improve the efficiency of coupling
communications for IMS Shared Queue and WebSphere
MQ Shared Queue environments. The Coupling Facility
notifies only one connector in a sequential fashion. If the
shared queue is processed within a fixed period of time,
the other connectors do not need to be notified, saving the
cost of the false scheduling. If a shared queue is not read
within the time limit, then the other connectors are notified
as they were prior to CFCC Level 16.
With the introduction of the z10 EC, we have the concept
of n-2 on the hardware as well as the software. The z10 EC
participates in a Sysplex with System z10 BC, System z9,
z990 and z890 only and currently supports z/OS 1.8 and
higher.
For detailed information on IBM’s Parallel Sysplex technol-
03.ibm.com/systems/z/pso/.
When migrating CF levels, lock, list and cache structure
sizes might need to be increased to support new function.
For example, when you upgrade from CFCC Level 15 to
Level 16 the required size of the structure might increase.
This adjustment can have an impact when the system
allocates structures or copies structures from one coupling
facility to another at different CF levels.
Coupling Facility Control Code (CFCC) Level 16
CFCC Level 16 is being made available on the IBM
System z10 EC.
Improved service time with Coupling Facility Duplex-
ing enhancements: Prior to Coupling Facility Control
Code (CFCC) Level 16, System-Managed Coupling
Facility (CF) Structure Duplexing required two duplexing
protocol exchanges to occur synchronously during pro-
cessing of each duplexed structure request. CFCC Level
16 allows one of these protocol exchanges to complete

vice time, with more benefits when the Coupling Facilities

environment.

Coupling Facility Configuration Alternatives
IBM offers multiple options for configuring a functioning
Coupling Facility:
ing enhancements described previously in the section titled
“Coupling Facility Control Code (CFCC) Level 16”.
• Standalone Coupling Facility: The standalone CF
provides the most “robust” CF capability, as the CPC is
wholly dedicated to running the CFCC microcode — all
of the processors, links and memory are for CF use
only. A natural benefit of this characteristic is that the
standalone CF is always failure-isolated from exploiting
z/OS software and the server that z/OS is running on for
environments without System-Managed CF Structure
Duplexing. While there is no unique standalone coupling
facility model offered with the z10 EC, customers can
achieve the same physically isolated environment as on
prior mainframe families by ordering a z10 EC, z9 EC, z9
BC, and z990 with PUs characterized as Internal Cou-
pling Facilities (ICFs). There are no software charges
associated with such a configuration.
Parallel Sysplex Coupling Connectivity
The Coupling Facilities communicate with z/OS images in
the Parallel Sysplex environment over specialized high-
speed links. As processor performance increases, it is
important to also use faster links so that link performance
does not become constrained. The performance, avail-
ability and distance requirements of a Parallel Sysplex
environment are the key factors that will identify the appro-
priate connectivity option for a given configuration.
• Internal Coupling Facility (ICF): Customers consider-
ing clustering technology can get started with Parallel
Sysplex technology at a lower cost by using an ICF
instead of purchasing a standalone Coupling Facility.
An ICF feature is a processor that can only run Coupling
Facility Control Code (CFCC) in a partition. Since CF
LPARs on ICFs are restricted to running only CFCC,
there are no IBM software charges associated with
ICFs. ICFs are ideal for Intelligent Resource Director and
resource sharing environments as well as for data shar-
ing environments where System-Managed CF Structure
Duplexing is exploited.
When connecting between System z10, System z9 and
z990/z890 servers the links must be configured to operate
in Peer Mode. This allows for higher data transfer rates
to and from the Coupling Facilities. The peer link acts
simultaneously as both a CF Sender and CF Receiver link,
reducing the number of links required. Larger and more
data buffers and improved protocols may also improve
long distance performance.

Introducing long reach InfiniBand coupling links
The IBM System z10 EC will support up to 32 PSIFB links
as compared to 16 PSIFB links on System z9 servers. For
either z10 EC or z9, there must be less than or equal to a
total of 32 PSIFBs and ICB-4 links.
Now, InfiniBand can be used for Parallel Sysplex coupling
and STP communication at unrepeated distances up to
10 km (6.2 miles) and greater distances when attached to
qualified optical networking solutions. InfiniBand coupling
links supporting extended distance is referred to as Long
Reach 1x (one pair of fiber) InfiniBand.
InfiniBand coupling links are CHPID type CIB.
Coupling Connectivity for Parallel Sysplex
You now have five coupling link options for communication
in a Parallel Sysplex environment:
• Long Reach 1x InfiniBand coupling links support single
data rate (SDR) at 2.5 gigabits per second (Gbps) when
connected to a DWDM capable of SDR (1x IB-SDR).
1. Internal Coupling Channels (ICs) can be used for
internal communication between Coupling Facilities
(CFs) defined in LPARs and z/OS images on the same
server.
• Long Reach 1x InfiniBand coupling links support double
data rate (DDR) at 5 Gbps when connected to a DWDM
capable of DDR (1x IB-DDR).
2. Integrated Cluster Bus-4 (ICB-4) is for short distances.
ICB-4 links use 10 meter (33 feet) copper cables, of
which 3 meters (10 feet) is used for internal routing and
strain relief. ICB-4 is used to connect z10 EC-to-z10 EC,
z10 BC, z9 EC, z9 BC, z990, and z890. Note. If connect-
ing to a z10 BC or a z9 BC with ICB-4, those servers
cannot be installed with the nonraised floor feature. Also,
if the z10 BC is ordered with the nonraised floor feature,
ICB-4 cannot be ordered.
The link data rate will auto-negotiate from SDR to DDR
depending upon the capability of the attached equipment.
Other advantages of Parallel Sysplex using InfiniBand
(PSIFB):
• InfiniBand coupling links also provide the ability to
define up to 16 CHPIDs on a single PSIFB port, allow-
ing physical coupling links to be shared by multiple
sysplexes. This also provides additional subchannels for
Coupling Facility communication, improving scalability,
and reducing contention in heavily utilized system con-
figurations. It also allows for one CHPID to be directed
to one CF, and another CHPID directed to another CF on
the same target server, using the same port.
3. 12x InfiniBand coupling links (12x IB-SDR or 12x
IB-DDR) offer an alternative to ISC-3 in the data center
and facilitate coupling link consolidation. Physical links
can be shared by multiple operating system images or
Coupling Facility images on a single system. The 12x
InfiniBand links support distances up to 150 meters (492
feet) using industry-standard OM3 50 micron multimode
fiber optic cables.
• Like other coupling links, external InfiniBand coupling
links are also valid to pass time synchronization signals
for Server Time Protocol (STP). Therefore the same
coupling links can be used to exchange timekeeping
information and Coupling Facility messages in a Parallel
Sysplex environment.
4. Long Reach 1x InfiniBand coupling links (1x IB-SDR
or 1x IB-DDR) are an alternative to ISC-3 and offer
greater distances with support for point-to-point unre-
peated distances up to 10 km (6.2 miles) using 9 micron
single mode fiber optic cables. Greater distances can
be supported with System z-qualified optical networking
solutions. Long Reach 1x InfiniBand coupling links sup-
port the same sharing capabilities as the 12x InfiniBand
version, allowing one physical link to be shared by
multiple operating system images or Coupling Facility
images on a single system.
• The IBM System z10 EC also takes advantage of
InfiniBand as a higher-bandwidth replacement for the
Self-Timed Interconnect (STI) I/O interface features
found in prior System z servers.

Time synchronization and time accuracy on z10 EC
Server Time Protocol (STP)
If you require time synchronization across multiple servers
(for example you have a Parallel Sysplex environment) or
you require time accuracy either for one or more System
z servers or you require the same time across heteroge-
STP is a message-based protocol in which timekeeping
information is transmitted between servers over externally
defined coupling links. ICB-4, ISC-3, and InfiniBand cou-
pling links can be used to transport STP messages.
®
neous platforms (System z, UNIX, AIX , etc.) you can meet
these requirements by either installing a Sysplex Timer
Model 2 (9037-002) or by implementing Server Time Proto-
col (STP).
Server Time Protocol (STP) Enhancements
STP configuration and time information restoration
after Power on Resets (POR) or power outage: This
enhancement delivers system management improvements
by restoring the STP configuration and time information
after Power on Resets (PORs) or power failure that affects
both servers of a two server STP-only Coordinated Timing
Network (CTN). To enable this function the customer has to
select an option that will assure than no other servers can
join the two server CTN. Previously, if both the Preferred
Time Server (PTS) and the Backup Time Server (BTS)
experienced a simultaneous power outage (site failure),
or both experienced a POR, reinitialization of time, and
special roles (PTS, BTS, and CTS) was required. With this
enhancement, you will no longer need to reinitialize the
time or reassign the roles for these events.
The Sysplex Timer Model 2 is the centralized time source
that sets the Time-Of-Day (TOD) clocks in all attached
servers to maintain synchronization. The Sysplex Timer
Model 2 provides the stepping signal that helps ensure
that all TOD clocks in a multi-server environment incre-
ment in unison to permit full read or write data sharing with
integrity. The Sysplex Timer Model 2 is a key component of
®
an IBM Parallel Sysplex environment and a GDPS avail-
ability solution for On Demand Business.
The z10 EC server requires the External Time Reference
(ETR) feature to attach to a Sysplex Timer. The ETR fea-
ture is standard on the z10 EC and supports attachment
at an unrepeated distance of up to three kilometers (1.86
miles) and a link data rate of 8 Megabits per second.
The distance from the Sysplex Timer to the server can be
extended to 100 km using qualified Dense Wavelength
Division Multiplexers (DWDMs). However, the maximum
repeated distance between Sysplex Timers is limited to
40 km.
Preview - Improved STP System Management with
new z/OS Messaging: This is a new function planned to
generate z/OS messages when various hardware events
that affect the External Time Sources (ETS) configured for
an STP-only CTN occur. This may improve problem deter-
mination and correction times. Previously, the messages
were generated only on the Hardware Management Con-
sole (HMC).
The ability to generate z/OS messages will be supported
on IBM System z10 and System z9 servers with z/OS 1.11
(with enabling support rolled back to z/OS 1.9) in the
second half of 2009.

The following STP enhancements are available on System
z10 and System z9 servers.
In comparison, the IBM Sysplex Timer is designed to
maintain an accuracy of 100 microseconds when attached
to an ETS with a PPS output. If STP is configured to use
a dial-out time service or an NTP server without PPS, it is
designed to provide a time accuracy of 100 milliseconds
to the ETS device.
The STP feature and the latest Machine Change Levels are
required.
Enhanced Network Time Protocol (NTP) client support:
This enhancement addresses the requirements for those
who need to provide the same accurate time across het-
erogeneous platforms in an enterprise.
For this enhancement, the NTP output of the NTP server
has to be connected to the Support Element (SE) LAN,
and the PPS output of the same NTP server has to be con-
nected to the PPS input provided on the External Time
Reference (ETR) feature of the System z10 or System z9
server.
The STP design has been enhanced to include support
for a Simple Network Time Protocol (SNTP) client on the
Support Element. By configuring an NTP server as the
STP External Time Source (ETS), the time of an STP-only
Coordinated Timing Network (CTN) can track to the time
provided by the NTP server, and maintain a time accuracy
of 100 milliseconds.
Continuous availability of NTP servers used as Exter-
nal Time Source: Improved External Time Source (ETS)
availability can now be provided if you configure different
NTP servers for the Preferred Time Server (PTS) and the
Backup Time Server (BTS). Only the PTS or the BTS can
be the Current Time Server (CTS) in an STP-only CTN.
Prior to this enhancement, only the CTS calculated the
time adjustments necessary to maintain time accuracy.
With this enhancement, if the PTS/CTS cannot access the
NTP server or the pulse per second (PPS) signal from the
NTP server, the BTS, if configured to a different NTP server,
may be able to calculate the adjustment required and
propagate it to the PTS/CTS. The PTS/CTS in turn will per-
form the necessary time adjustment steering.
Note: NTP client support has been available since October
2007.
Enhanced accuracy to an External Time Source: The
time accuracy of an STP-only CTN has been improved by
adding the capability to configure an NTP server that has
a pulse per second (PPS) output signal as the ETS device.
This type of ETS device is available worldwide from sev-
eral vendors that provide network timing solutions.
STP has been designed to track to the highly stable,
accurate PPS signal from the NTP server, and maintain
an accuracy of 10 microseconds as measured at the PPS
input of the System z server. A number of variables such
as accuracy of the NTP server to its time source (GPS,
radio signals for example), and cable used to connect the
PPS signal will determine the ultimate accuracy of STP to
Coordinated Universal Time (UTC).
This avoids a manual reconfiguration of the BTS to be the
CTS, if the PTS/CTS is not able to access its ETS. In an
ETR network when the primary Sysplex Timer is not able
to access the ETS device, the secondary Sysplex Timer
takes over the role of the primary - a recovery action not

always accepted by some environments. The STP design
provides continuous availability of ETS while maintaining
the special roles of PTS and BTS assigned by the enter-
prise.
z server, STP now has the capability of receiving notifica-
tion that customer power has failed and that the IBF is
engaged. When STP receives this notification from a server
that has the role of the PTS/CTS, STP can automatically
reassign the role of the CTS to the BTS, thus automating
the recovery action and improving availability.
The improvement is available when the ETS is configured
as an NTP server or an NTP server using PPS.
STP configuration and time information saved across
Power-on-Resets (POR) or power outages: This
enhancement delivers system management improvements
by saving the STP configuration across PORs and power
failures for a single server STP-only CTN. Previously, if
there was a POR of the server or the server experienced
a power outage, the time and assignment of the PTS and
CTS roles would have to be reinitialized. You will no longer
need to reinitialize the time or reassign the role of PTS/CTS
across POR or power outage events.
NTP server on Hardware Management Console (HMC):
Improved security can be obtained by providing NTP
server support on the HMC. If an NTP server (with or with-
out PPS) is configured as the ETS device for STP, it needs
to be attached directly to the Support Element (SE) LAN.
The SE LAN is considered by many users to be a private
dedicated LAN to be kept as isolated as possible from the
intranet or Internet.
Since the HMC is normally attached to the SE LAN, pro-
viding an NTP server capability on the HMC addresses
the potential security concerns most users may have for
attaching NTP servers to the SE LAN. The HMC, using
a separate LAN connection, can access an NTP server
available either on the intranet or Internet for its time
source. Note that when using the HMC as the NTP server,
there is no pulse per second capability available. There-
Note: This enhancement is also available on the z990 and
z890 servers, in addition to System z10 and System z9
servers.
Application Programming Interface (API) to automate
STP CTN reconfiguration: The concept of “a pair and
a spare” has been around since the original Sysplex
fore, you should not configure the ETS to be an NTP server Couple Data Sets (CDSs). If the primary CDS becomes

unavailable, the backup CDS would take over. Many sites
have had automation routines bring a new backup CDS
online to avoid a single point of failure. This idea is being
extended to STP. With this enhancement, if the PTS fails
and the BTS takes over as CTS, an API is now available
on the HMC so you can automate the reassignment of the
PTS, BTS, and Arbiter roles. This can improve availability
by avoiding a single point of failure after the BTS has taken
over as the CTS.
Enhanced STP recovery when Internal Battery Feature
is in use: Improved availability can be obtained when
power has failed for a single server (PTS/CTS), or when
there is a site power outage in a multisite configuration
where the PTS/CTS is installed (the site with the BTS is
a different site not affected by the power outage). If an

Time task on the HMC. For additional details on the API,
please refer to System z Application Programming Inter-
faces, SB10-7030-11.
As processor and Coupling Facility link technologies have
improved, the requirement for time synchronization toler-
ance between systems in a Parallel Sysplex environment
has become ever more rigorous. In order to enable any
exchange of time stamped information between systems
in a sysplex involving the Coupling Facility to observe the
correct time ordering, time stamps are now included in
the message-transfer protocol between the systems and
the Coupling Facility. Therefore, when a Coupling Facility
is configured on any System z10 or System z9, the Cou-
pling Facility will require connectivity to the same 9037
Sysplex Timer or Server Time Protocol (STP) configured
Coordinated Timing Network (CTN) that the systems in its
Parallel Sysplex cluster are using for time synchroniza-
tion. If the ICF is on the same server as a member of its
Parallel Sysplex environment, no additional connectivity is
required, since the server already has connectivity to the
Sysplex Timer.
Additional information is available on the STP Web page:

• Server Time Protocol Planning Guide, SG24-7280
• Server Time Protocol Implementation Guide, SG24-7281
Internal Battery Feature Recommendation

• CTN with 2 servers, install IBF on at least the PTS/CTS
– Also recommend IBF on BTS to provide recovery pro-
tection when BTS is the CTS
– CTN with 3 or more servers IBF not required for STP
recovery, if Arbiter configured
However, when an ICF is configured on any z10 which
does not host any systems in the same Parallel Sysplex
cluster, it is necessary to attach the server to the 9037
Sysplex Timer or implement STP.
Two data centers
• CTN with 2 servers (one in each data center) install IBF
on at least the PTS/CTS

HMC DVD drive. This new function does not require an
external network connection between z/VM and the HMC,
but instead uses the existing communication path between
the HMC and the SE.
This support is intended for environments that have no
alternative, such as a LAN-based server, for serving the
DVD contents for Linux installations. The elapsed time for
installation using the HMC DVD drive can be an order of
magnitude, or more, longer than the elapsed time for LAN-
based alternatives.
HMC z/VM Tower systems management enhancements
Building upon the previous VM systems management
support from the Hardware Management Console (HMC),
which offered management support for already defined
virtual resources, new HMC capabilities are being made
available allowing selected virtual resources to be defined.
In addition, further enhancements have been made for
managing defined virtual resources.
Using the current support and the z/VM support, z/VM
can be installed in an LPAR and both z/VM and Linux on
System z can be installed in a virtual machine from the
HMC DVD drive without requiring an external network
setup or a connection between an LPAR and the HMC.
Enhancements are designed to deliver out-of-the-box inte-
grated graphical user interface-based (GUI-based) manage-
ment of selected parts of z/VM. This is especially targeted to
deliver ease-of-use for enterprises new to System z.
This addresses security concerns and additional configura-
tion efforts using the only other previous solution of the exter-
nal network connection from the HMC to the z/VM image.
This helps to avoid the purchase and installation of
additional hardware or software, which may include
complicated setup procedures. You can more seam-
lessly perform hardware and selected operating system
management using the HMC Web browser-based user
interface.
Enhanced installation support using the HMC is exclusive
to System z10 and is supported by z/VM.
Enhanced installation support for z/VM using the HMC:

Fiber Quick Connect for FICON LX
Environments
System z servers. Now Geographically Dispersed Open
Clusters (GDOC) is designed to address this need for
open systems. GDPS 3.5 will support GDOC for coordi-
nated disaster recovery across System z and non-System
z servers if Veritas Cluster Server is already installed.
GDPS and the Basic HyperSwap (available with z/OS
V1.9) solutions help to ensure system failures are invisible
to employees, partners and customers with dynamic disk-
swapping capabilities that ensure applications and data
are available.
Fiber Quick Connect (FQC), an optional feature on z10 EC,
is now being offered for all FICON LX (single mode fiber)
channels, in addition to the current support for ESCON.
FQC is designed to significantly reduce the amount of
time required for on-site installation and setup of fiber
optic cabling. FQC facilitates adds, moves, and changes
of ESCON and FICON LX fiber optic cables in the data
center, and may reduce fiber connection time by up to
80%.
FQC is for factory installation of IBM Facilities Cabling
Services – Fiber Transport System (FTS) fiber harnesses
for connection to channels in the I/O cage. FTS fiber har-
nesses enable connection to FTS direct-attach fiber trunk
cables from IBM Global Technology Services.
GDPS is a multi-site or single-site end-to-end application
availability solution that provides the capability to manage
remote copy configuration and storage subsystems
(including IBM TotalStorage), to automate Parallel Sysplex
operation tasks and perform failure recovery from a single
point of control.
Note: FQC supports all of the ESCON channels and all of
the FICON LX channels in all of the I/O cages of the server.
GDPS helps automate recovery procedures for planned
and unplanned outages to provide near-continuous avail-
ability and disaster recovery capability.

• OSA-Express can be Gigabit Ethernet (GbE),
1000BASE-T Ethernet or Fast Ethernet.
• If ICB-3 is required on the system, it will use up a single
I/O slot for every 2 ICB-3 to accommodate the STI-3
card.
Note: In the first and second I/O cage, the last domain in
the I/O cage is normally used for ISC-3 and ICB-3 links.
When the first 6 domains in an I/O cage are full, additional
I/O cards will be installed in the next I/O cage. When all
the first 6 domains in all I/O cages are full and no Coupling
link or PSC cards are required, the last domain in the I/O
cage will be used for other I/O cards making a total of 28
per cage.

Statement of Direction
IBM intends to support optional water cooling on future
high end System z servers. This cooling technology will
tap into building chilled water that already exists within the
datacenter for computer room air conditioning systems.
External chillers or special water conditioning will not be
required. Water cooling technology for high end System z
servers will be designed to deliver improved energy effi-
ciencies.
one, in which the following Statement of Direction was
made: IBM intends to remove the Dynamic ICF expansion
function from future System z servers.
The System z10 will be the last server to support connec-
tions to the Sysplex Timer (9037). Servers that require time
synchronization, such as to support a base or Parallel Sys-
plex, will require Server Time Protocol (STP). STP has been
available since January 2007 and is offered on the System
z10, System z9, and zSeries 990 and 890 servers.
IBM intends to support the ability to operate from High
Voltage DC power on future System z servers. This will
be in addition to the wide range of AC power already
supported. A direct HV DC datacenter power design can
improve data center energy efficiency by removing the
need for an additional DC to AC inversion step.
ESCON channels to be phased out: It is IBM's intent for
ESCON channels to be phased out. System z10 EC and
System z10 BC will be the last servers to support greater
than 240 ESCON channels.
ICB-4 links to be phased out: Restatement of SOD) from
RFA46507) IBM intends to not offer Integrated Cluster Bus-
4 (ICB-4) links on future servers. IBM intends for System
z10 to be the last server to support ICB-4 links.
The System z10 will be the last server to support Dynamic
ICF expansion. This is consistent with the System z9 hard-
ware announcement 107-190 dated April 18, 2007, IBM
System z9 Enterprise Class (z9 EC) and System z9 Busi-
ness Class (z9 BC) – Delivering greater value for every-
