The x3550M2 uses up to 16 DIMMs with 128GB of registered 1333MHz DDR3 memory with
Chipkill™ ECC (Error Checking and Correcting) protection—for high performance and reliability.
For even higher levels of availability, the x3550M2 also offers online memory mirroring. Up to 4
integrated high-speed Gigabit Ethernet controllers with TOE (TCP Offload Engine) and Jumbo
Frame support are available, as are two high-performance adapter slots (PCIe x16). The
x3550M2 offers an optional embedded hypervisor to manage your virtual workloads.
The x3550 M2 offers a choice of up to six high-performance hot-swap hard disk drives with an
internal storage capacity of 1.8TB (six 2.5-inch hot-swap Serial-Attached SCSI (SAS) or SATA
HDDs) Optional solid-state drives are also available to keep power low and improve resiliency and
offer up to 300GB of storage. The server supports a choice of four IBM ServeRAID® storage
controllers which provide broad levels of hardware-based RAID solutions. The ultradense 1U
form factor allows businesses to increase their computing power and spread their workload
without outgrowing their current data center. Up to 42 of these 1U servers can be installed in a
single 42U rack, for a total of up to 84 processors and 336 processor cores, offering tremendous
deployment flexibility. Optional Advanced Connectivity Technology (ACT) interconnect cabling
reduces cable clutter and cost and minimizes installation time when interconnecting many rack-
mounted servers.
Standard in the x3550 M2 is the Integrated Management Module (IMM) that enables the user to
manage and control the server easily—both locally and remotely. In conjunction with the IMM, the
x3550 M2 comes with an altitude sensor (altimeter), which governs fan rotation based on
altitude to help lower your energy consumption. The IMM offers a high level of manageability that
is designed to keep costs down and the system up—even when network usage increases. IBM’s
innovative pop-out/drop-down light path diagnostics panel enables quick servicing of the
system if a problem develops. These advanced features help maximize network availability by
increasing uptime, as do hot simple-swap solid-state drives; hot-swap/redundant SAS or
SATA HDDs, redundant ultra-efficient power supplies and fans; Active Memory™; integrated
RAID; temperature-controlled fans with Calibrated Vectored Cooling™; IPMI 2.0 support,
including highly secure remote power control and Serial over LAN; as well as text-console
redirect over LAN.
Another improvement with the new generation of X-Architecture is the replacement of old BIOS

Availability and Serviceability
The x3550 M2 provides many features to simplify serviceability and increase system uptime:
•
x3550 M2 servers use Chipkill ECC memory protection3. Chipkill memory is up to 16X better
than standard ECC memory at correcting memory errors. This can help reduce downtime
caused by memory errors.
•
•
The x3550 M2 offers selectable memory mirroring for redundancy in the event of a non-
correctable memory failure
Toolless cover removal provides easy access to upgrades and serviceable parts. Similarly,
2 Data transfer rates may be less than the maximum possible.

Leadership enterprise server with significantly lower cost of ownership in a highly available and
expandable, rack-dense, 1U dual-socket server
the Virtual Media Key and the ServeRAID-BR10i controller can be installed and replaced
without tools. This means less time (and therefore less money) spent servicing the x3550 M2.
Similarly, hot-swap/redundant HDDs, fans and power supplies, as well as online mirrored
memory, mean greater system uptime while these components are being serviced.
•
•
•
New toolless slides ship with the server, together with a Cable Management Arm (CMA),
that allows the rack server to easily slide into place
IBM Thermal Diagnostics allows the administrator to evaluate thermal data on the server
without taking the hardware offline. This can provide greater server uptime.
The drop-down light path diagnostics panel and individual light path LEDs quickly lead the
technician to failed (or failing) components. This simplifies servicing, speeds up problem
resolution and helps improve network availability.
•
•
Integrated RAID-1 disk mirroring and RAID-10 striped mirrored arrays standard enable
the server to keep operating in the event of a failure to any one drive.
IPMI 2.0 supports highly secure remote system power control using data encryption. This
allows an administrator to restart a server without having to visit it in person, saving travel time
and getting the server back up and running quickly and securely. It also adds new features to
those provided by IPMI 1.5, including VLAN support, Serial over LAN, enhanced
authentication and encryption algorithms (RMCP+, SHA-1, AES) and a firmware firewall.
•
•
Altitude- and temperature-controlled fans adjust to compensate for changing thermal
characteristics. At the lower speeds they draw less power and suffer less wear. Equally
important in a crowded data center, temperature-controlled fans produce less ambient noise in
the data center than if they were constantly running at full speed.
The three-year (parts and labor) limited onsite warranty4 helps afford you peace of mind
and greater investment protection than a one-year warranty does.
Key Features
High-Performance Xeon 5500 Series Processors
The x3550 M2 supports up to two high-performance Intel Xeon processors, allowing you to
upgrade to a second processor as your business needs require. The x3550 M2 offers a choice of
processor clock rates, memory access speeds and energy efficiency, including:
•
95W quad-core Xeon 5500 Series Processor advanced performance models X5570, X5560,
or X5550 at 2.93, 2.8, 2.66GHz respectively running 6.4GT (gigatransfers/second) with 8MB
of L3 processor cache, 1333MHz memory access, and Intel Turbo Boost technology.
•
80W quad-core Xeon 5500 Series Processor standard performance models E5540, E5530,
or E5520 at 2.53, 2.4, 2.26GHz respectively running 5.8GT with 8MB of L3 processor cache,
1066MHz memory access, and Intel Turbo Boost technology.
•
•
80W quad-core Xeon 5500 Series Processor basic models E5506 and E5504 at 2.13 and
2.0GHz running 4.8GT with 4MB of L3 processor cache and 800MHz memory access.
60W quad-core Xeon 5500 Series Processor low-voltage models 5520, L5506 at 2.26,
2.13GHz respectively running 5.8GTand 4.8GT with 8MB and 4MB of L3 processor cache,
1066MHz memory access, and Turbo Boost technology.
•
80W dual-core Xeon 5500 Series Processor model E5502 at 1.86GHz running 4.8GT with
4MB of L3 processor cache and 800MHz memory access.
With the Xeon 5500 Series processors, Intel has diverged from its traditional Symmetric
Multiprocessing (SMP) architecture to a Non-Uniform Memory Access (NUMA) architecture. The
Xeon 5500 processors are connected through a serial coherency link called QuickPath
Interconnect (QPI). QPI is capable of 6.4, 5.6 or 4.8 GT/s (gigatransfers per second), depending
on the processor model.
Dual-core Xeon processors contain two complete processor cores; quad-core processors,
similarly, contain four cores. Some processors contain one unified cache shared by all cores,
while other processors have multiple independent caches (one per pair of cores). The shared
cache is dynamically allocated between the cores as needed. The multiple cores appear to
software as multiple physical processors. The dual-core processors offer considerably higher
performance than a same-speed Xeon processor with a single core. Likewise, quad-core
processors offer considerably higher performance than a same-speed Xeon processor with dual
cores.
Turbo Boost Technology dynamically turns off unused processor cores and increases the clock
speed of the cores in use, by up to two model frequencies. For example, with three cores active,

a 2.26GHz processor can run the cores at 2.4GHz. With only one or two cores active, the same
processor can run those cores at 2.53GHz. Similarly, a 2.93GHz processor can run at 3.06GHz
or even 3.33GHz. When the cores are needed again, they are dynamically turned back on and
the processor frequency is adjusted accordingly.
Intel Extended Memory 64 Technology (EM64T) 64-bit extensions allow the Xeon processor to
use large memory addressing when running with a 64-bit operating system. This in turn lets
individual software processes directly access more than 4GB of RAM, which was the limit of 32-
bit addressing. This can result in much higher performance for certain kinds of programs, such as
database management and CAD. Additional registers and instructions (SSE3) can further boost
performance for applications written to use them. Contact your software provider to determine
their software support for EM64T.
Intelligent Power Capability powers individual processor elements on and off as needed, to
reduce power draw.
Execute Disable Bit functionality can help prevent certain classes of malicious buffer overflow
attacks when combined with a supporting operating system.
DDR-3 Registered Memory with Chipkill ECC Protection
The x3550 M2 ships with registered double data rate III (DDR-3) memory and provides Active
Memory features, including advanced Chipkill memory protection (optionally), for up to 16X
better error correction than standard ECC memory. In addition to offering better performance than
DDR-2 or fully-buffered memory, DDR-3 memory also uses less energy. DDR-2 memory already
offered up to 37% lower energy use than fully buffered memory. Now, a generation later, DDR-3
memory is even more efficient, using 22% less energy than DDR-2 memory.
The x3550 M2 supports up to 128GB of memory in sixteen DIMM slots. Redesign in the
architecture of the Xeon 5500 series processors bring radical changes in the way memory works
in these servers. For example, the Xeon 5500 series processor integrates the memory
controller inside the processor, resulting in two memory controllers in a 2-socket system. Each
memory controller has three memory channels. Depending on the type of memory, population of
memory, and processor model, the memory may be clocked at 1333MHz, 1066MHz or 800MHz.

Note: If only one processor is installed, only the first eight DIMM slots can be used. Adding a
second processor not only doubles the amount of memory available for use, but also doubles the
number of memory controllers, thus doubling the system memory bandwidth. If you add a second
processor, but no additional memory for the second processor, the second processor has to
access the memory from the first processor “remotely,” resulting in longer latencies and lower
performance. The latency to access remote memory is almost 75% higher than local memory
access. So, the goal should be to always populate both processors with memory.
The X55xx models support up to 1333MHz memory clock speed, while the E55xx-and-up and
L55xx-and-up models support up to 1066MHz clock speed, and the E550x models support
800MHz clock speed. Using 1333MHz memory (where supported) versus 1066MHz offers up to
9% better performance, while 1066MHz memory produces up to 28% better performance than
800MHz memory.
Xeon 5550 series processors access memory with almost 50% lower latency than the previous
generation 5400 series processors. That can result in faster processing of latency-sensitive
workloads.

Leadership enterprise server with significantly lower cost of ownership in a highly available and
expandable, rack-dense, 1U dual-socket server
This new processor design comes with some trade-offs in memory capacity, performance, and
cost: For example, greater memory capacity comes with lower memory speed. Alternatively, it
is possible to achieve the same memory capacity at lower cost but at a lower memory speed.
Regardless of memory speed, the Xeon 5500 platform represents a significant improvement in
memory bandwidth over the previous Xeon 5400 platform. At 1333MHz, the improvement is
almost 500% over the previous generation. This huge improvement is mainly due to the dual
integrated memory controllers and faster DDR-3 1333MHz memory. Throughput at 800MHz is 25
gigabytes per second (GBps); at 1066MHz it’s 32GBps; and at 1333MHz it’s 35GBps. This
improvement translates into improved application performance and scalability.
Memory interleaving refers to how physical memory is interleaved across the physical DIMMs. A
balanced system provides the best interleaving. A Xeon 5500 processor-based system is
balanced when all memory channels on a socket have the same amount of memory.
A memory rank is simply a segment of memory that is addressed by a specific address bit.
DIMMs typically have 1, 2 or 4 memory ranks, as indicated by their size designation.
•
•
•
A typical memory DIMM description is 2GB 4Rx8 DIMM
The 4R designator is the rank count for this particular DIMM (R for rank = 4)
The x8 designator is the data width of the rank
It is important to ensure that DIMMs with appropriate number of ranks are populated in each
channel for optimal performance. Whenever possible, it is recommended to use dual-rank
DIMMs in the system. Dual-rank DIMMs offer better interleaving and hence better performance
than single-rank DIMMs. For instance, a system populated with six 2GB dual-rank DIMMs
outperforms a system populated with six 2GB single-rank DIMMs by 7% for SPECjbb2005. Dual-
rank DIMMs are also better than quad-rank DIMMs because quad-rank DIMMs will cause the
memory speed to be down-clocked.
Another important guideline is to populate equivalent ranks per channel. For instance, mixing
one single-rank DIMM and one dual-rank DIMM in a channel should be avoided.
Note: It is important to ensure that all three memory channels in each processor are populated.
The relative memory bandwidth decreases as the number of channels populated decreases. This
is because the bandwidth of all the memory channels is utilized to support the capability of the
processor. So, as the channels are decreased, the burden to support the requisite bandwidth is
increased on the remaining channels, causing them to become a bottleneck.
For increased availability, the x3550 M2 offers an additional (but mutually exclusive) level of IBM
Active Memory protection: online memory mirroring..
Memory mirroring works much like disk mirroring. The total memory is divided into two channels.
Data is written concurrently to both channels. If a DIMM fails in one of the DIMMs in the primary
channel, it is instantly disabled and the mirrored (backup) memory in the other channel becomes
active (primary) until the failing DIMM is replaced. One-half of total memory is available for use
with mirroring enabled. (Note: Due to the double writes to memory, performance is affected.)
Mirroring is handled at the hardware level; no operating system support is required.
DDR-3 memory is available in 1GB, 2GB, 4GB and 8GB DIMMs. DIMMs are installed individually
(not in pairs).
Drive Bays
The x3550 M2 contains six drive bays in all. Hot-swap drives may be inserted or removed
through the front of the server without powering off the system. Simple-swap solid-state drives
can be inserted or removed through the front of the server as well; however, the system power
must first be turned off.
For additional storage, a direct-attach, NAS or SAN external expansion option can be added,
using an optional controller.
A 24X/24X/24X/8X5 speed (ultraslim, 0.5”) CD-RW/DVD-ROM Combo drive with an IDE interface
ships standard in all x3550 M2 servers. No diskette drive is supplied with any model; an external
USB floppy drive may be used, if needed.
Disk Controllers
All SAS-equipped x3550 M2 models include an integrated hardware based ServeRAID-BR10i
SAS/SATA controller. This controller supports up to six internal SAS, SATA or solid-state
drives.
5 Variable read rate. Actual playback speed varies and is often less than the maximum possible.

replacing the older parallel PCI and PCI-X buses. A x16 PCIe adapter offers approximately eight
ttimes the maximum throughput of a 133MHz PCI-X adapter7. (A x1 adapter offers throughput
similar to a 66MHz PCI-X slot.)
There is a built-in riser card in x3550 M2 that provides a PCIe connector (x8 connector wired with
x4 lanes) for an internal RAID card ( MR10i plus one USB connector reserved for an internal
USB Flash memory key to support Hypervisor.. There is no internal Tape drive support in x3550

Dual Gigabit Ethernet Controllers
The x3550 M2 includes two integrated Broadcom 5709 Gigabit Ethernet controllers for up to
10X higher maximum throughput than a 10/100 Ethernet controller, as well as support for Jumbo
Frames and TOE (TCP Offload Engine).
Jumbo Frames—those larger than the standard frame (packet) size of 1,500 bytes—can be
more efficient, dramatically increasing network performance and reducing server CPU overhead.
TOE helps improve overall system performance by offloading TCP/IP protocol processing from
the system microprocessor to the onboard Ethernet TOE processor. There is no additional
charge for this capability.
It also supports highly secure remote power management using IPMI 2.0, plus Wake on LAN®
and PXE (Preboot Execution Environment) flash interface. Optional PCI adapters offering failover
and load balancing between adapters are available for added throughput and increased system
availability.

iSCSI and RDMA are not supported
Two Broadcom 5709 Gigabit Ethernet Controllers (one on-board and one on optional daughter
card) provide four Gigabit ports supporting IEEE 802.3 for 1000Base-T, 100Base-TX, and
10Base-T applications (802.3, 802.3u, 802.3ab) through a RJ-45 connector to an Ethernet
network over a CAT 5 twisted-pair cable. This controller supports PXE 2.0 remote boot, TCPIP
Offload Engine (TOE), Internet SCSI (iSCSI), Remote Direct Memory Access (RDMA), and jumbo
frames (9KB). License key will be required to enable iSCSI and RDMA feature. There are two
green LEDs on the connector: Activity LED on the upper left side and Link Status LED on the
upper right side (viewed facing the connector). TOE support on Windows is available today. But it
requires Windows Scalable Network Pack (SNP) installation. Linux has no plan to support TOE at
this time. Please refer to TOE_RDMA_iSCSI.doc for technology details. Internet Protocol version
6 (IPv6) is supported.
Ultra-Efficient Cooling
Strategically located fans, combined with efficient airflow paths, provide highly effective system
cooling for the x3550 M2, known as Calibrated Vectored Cooling. The base server with one
power supply includes six hot-swap fan packs for redundant cooling. Each pack includes two
back-to-back fans with counter-rotating blades for a total of 12 fans. In addition, each power
supply also contains a fan.
The system contains three cooling zones. Zone 1 (incorporating two fan packs) cools all 16
DIMM sockets, Zone 2 (two fan packs) cools the primary processor, and Zone 3 (one or two fan
packs) cools the second processor (if installed).
The fans automatically adjust speeds in response to changing thermal requirements depending
on the zone and internal temperatures. When the temperature inside the server increases, the
fans speed up to maintain the proper ambient temperature. When the temperature returns to a
normal operating level, the fans return to their default speed. In addition, the Bosch BMP085
altimeter works in conjunction with IMM to govern fan rotation. At high altitudes the air is thinner

and doesn’t cool as well as at lower elevations. In most servers, the fans run fast all the time to
allow for use at high elevations, wasting power. The altimeter allows the IBM fans to run at lower
speeds at lower altitudes.
Why not simply run the fans at 100% capacity all the time? For several good reasons: to reduce
the ambient noise, reduce the wear-and-tear on the fans and reduce the server power draw. The
reduction in ambient noise and power draw may be relatively minor for a single server, but put
dozens or hundreds in a data center and it can make a big difference!
In addition, the server uses hexagonal ventilation holes in the chassis. Hexagonal holes can be
grouped more densely than round holes, providing greater airflow through the system cover.
This cooling scheme is important because newer, more powerful processors generate a
significant amount of heat, and heat must be controlled for the system to function properly.
There are temperature sensors on the planar placed to sense DIMM exhaust temperature, SAS
HDD exhaust temperature, and CPU2 exhaust temperature (through the altitude sensor).
Light Path Diagnostics
Light path diagnostics enables a technician to quickly identify and locate a failed or failing system
component, such as a specific fan or memory DIMM. This enables quick replacement of the
component, which helps increase server uptime and lower operating costs.
The front of the server has an LED indicator light to show possible component failures. If the front
LED indicates an error condition, by pressing a button on the front of the server an LED panel will
pop out and drop down for easy viewing without the need to open the server cover or remove the
server from the rack. The light path diagnostics panel tells the servicer which component requires
attention. In addition, many components have their own identifying LEDs. For example, each of
the eight memory modules has an LED next to the socket, as do both processors, all adapter
slots, all fans, all power supplies, the voltage regulator module and the service processor,
allowing the servicer to easily identify exactly which component needs servicing. By following the
“light path,” the component can be replaced quickly, and without guesswork. (Note: In the event
of a failed DIMM, the system will restart and mark the DIMM as bad while offline, thus allowing
the system to continue running, with reduced memory capacity, until serviced.)
Hot-Swap/Redundant Components
System availability is maximized through the extensive use of hot-swap and redundant
components, including:
•
•
Redundant memory protection (with memory mirroring enabled)
Hot-swap, redundant hard disk drives (with RAID-1/10 protection standard and three other
RAID levels optional)
•
•
Hot-swap, redundant power supplies
Hot-swap, redundant cooling fans
Other Features
•
Four USB 2.0 ports — Provides flexibility to add high-speed external devices. The USB 2.0
specification supports up to 480Mbps transfer rates. (Note: Not all USB 2.0 devices are
capable of achieving this rate.) Two ports are provided on the front of the server and four on
the back. USB ports can be used for pre-boot to an external drive, also for KB/mouse

Dual video ports — A Matrox G200eV SVGA video controller provides up to 1024x768
resolution, with a color depth of 32 bits at 85Hz refresh rate. To simplify local systems
management, one video port is provided on the front of the unit and one on the back.
•
•
Toolless slides — Allows quick rack installation and quicker upgrade and servicing of the
server.

removed and replaced without tools, including the CD-RW/DVD combo drive, hot-swap
HDDs, plus PCI, PCI-X and PCIe adapters, as well as the integrated ServeRAID BR10i and
Virtual Media Key. This can save a servicer significant time.

Rack Cable Management and KVM Console Switching
IBM Advanced Cabling Technology (ACT) is an optional feature that offers many advantages
over standard KVM cabling across the entire System x product line. So now you can interconnect
all of your servers with one smart cabling architecture. ACT cabling eliminates the need for one-
to-one direct connections between each server and a KVM switch by using a daisy-chain
approach.
The snarl of cabling behind most racks is at best inconvenient to work around and at worst an
expensive logistical nightmare, requiring the rewiring of servers, PDUs, KVM switches, and other
equipment whenever a rack server is added or removed. Even worse, the veil of cables blocks
rack airflow and can actually contribute to equipment failure due to overheating. ACT cabling is
the solution for reducing behind-the-rack cabling by as much as 87%.
The illustration below shows a sample ACT configuration:
Directly
Via Daisy-Chain
•
Max.16 servers per port
All CAT5, 5e, 6
cabling
Via Secondary
Switch
Conventional cabling has bulky KVM cables exiting each server, which then connect to a KVM
switch. The cables exiting a series of KVM switches must then be aggregated via additional KVM
switches and PDUs, which only increases the number—and cost—of cables, KVM switches and
PDUs. Instead, the daisy-chain approach of ACT cabling uses readily available, inexpensive
CAT5 and 6 cabling to considerably reduce the number of cables, KVM switches, and PDUs
needed, rather than increasing them. If a server is removed or added, no complicated rewiring is
needed. One cable connects the first server in the rack to the next, and so on. Up to 16 servers
form a chain; up to 8 chains can connect to one Local Console Manager (LCM); 16 LCMs can
connect to one Global Console Manager (GCM). In this manner, up to 2,048 servers can be
centrally managed. Equally importantly, with ACT—unlike some other offerings—everything is
done externally via cabling; no special adapters are required.
Extensive System Support Features
The IBM services and technical support portfolio provides world-class, consistent, high-quality
service and support. The x3550 M2 server offers a number of tools and services designed to
make ownership a positive experience. From the start, IBM programs make it easier for you to
plan for, configure and purchase System x servers, get them running and keep them running
long-term. These features include IBM Express Portfolio, IBM ServerProven®, IBM Standalone
Solutions Configuration Tool, IBM System x and BladeCenter Power Configurator, IBM
ServerGuide, IBM Electronic Service Agent™, Product Customization Services and extensive
technical support offerings.
The IBM ServerProven program provides the confidence that specific options and operating
systems have been tested on the server and are officially supported to work together. It is
updated frequently to ensure that the latest compatibility information is always at your fingertips.
The IBM Standalone Solutions Configuration Tool (SSCT) is a downloadable tool that
simplifies the often complex chore of configuring a full rack of servers (including blade servers)
and confirming that you have all the cables, power distribution units, KVM (keyboard, video and
mouse) switch boxes and other components you need, as well as the proper airflow clearances,
electrical circuits and other environmental conditions.

power needs, by providing the following information for specific configurations of System x and
BladeCenter systems: power input (watts), PDU sizing (amps), heat output (BTUs), airflow
requirements through chassis (CFM), VA rating, leakage current (mA), and peak inrush current
(amps).
IBM ServerGuide (installed from CD) simplifies the process of installing and configuring System
x servers. ServerGuide goes beyond mere hardware configuration by assisting with the
automated installation of the Microsoft® Windows® Server 2000 and 2003 operating systems,
device drivers and other system components, with minimal user intervention. (Drivers are also
included for support of Novell NetWare, Red Hat Linux and SUSE LINUX.) This focus on
deployment helps you reduce both you total cost of ownership and the complexity that
administrators and technical personnel face.
IBM Systems Director Service and Support Manager (previously called IBM Electronic Service
Agent™) is an innovative “call home” feature that allows System x and BladeCenter servers to
automatically report hardware problems to IBM support, which can even dispatch onsite service8
if necessary to those customers entitled to onsite support under the terms of their warranty or an
IBM Maintenance Agreement. Electronic Service Agent resides on a server and provides
electronic support and problem management capabilities through a highly secure electronic
dialogue between your systems and IBM. It monitors networked servers for hardware errors and
it can perform hardware and software inventories and report inventory changes to IBM. All
information sent to IBM is stored in a highly secure database and used for improved problem
determination.
Additional services include hardware warranty upgrades and factory-installed Product
Customization Services (PCS), such as asset tagging, hardware integration, software imaging
and operating systems personalization.
IBM offers extensive technical support by phone and via the Web. Support options include links
to forums/newsgroups, problem submission, online shopping support, service offerings, device

SSL (Secure Socket Layer) and LDAP (Lightweight Directory Access Protocol) support
IBM developed IBM Systems Director Active Energy Manager for x86 to put control of system
power-saving features at the fingertips of administrators. Active Energy Manager is designed to
take advantage of new features, such as monitoring power usage and balancing the performance
of the system according to available power input. It provides the ability to plan and predict power
consumption based on your hardware configuration. It also helps enable you to reduce the
infrastructure required for redundancy, by using fewer servers on smaller power feeds and
potentially lowering your overall data center support costs. It does this by inventorying all
components, then adding up the total power draw and tracking the usage. It also includes power
management and capping features to help administrators manage or reduce power usage.
Automatic Server Restart (ASR) helps reduce downtime by restarting the server automatically
in the event of a system lockup. ASR technology is a combination of hardware circuitry tied into
the server’s system reset function and a device driver. As long as the server continues running,
the ASR watchdog timer will keep being reset, but if the operating system crashes or the
hardware freezes somehow the ASR software will be unable to reset the hardware timer. If the
timer is not reset within five minutes, it automatically triggers the ASR hardware, which
immediately restarts the server (and logs an ASR event with IBM Systems Director). These
features are designed so that no more than five minutes can pass before the server is restarted.
Wake on LAN permits the server to be remotely powered on if it has been shut off. Once
powered up, the server can be controlled across the network, using the Preboot Execution
Environment (PXE).
Like Wake on LAN, PXE is system firmware. It enables software such as the optional IBM
Remote Deployment Manager to take control of a system before the BIOS, operating system or
applications are loaded (using Wake on LAN/PXE) and lets an administrator perform many low-
level tasks remotely that would otherwise require a visit to each system. These tasks may include
such things as formatting a hard disk drive, updating system firmware, or deploying a Windows or
Linux operating system.
Text Console Redirection support allows the administrator to remotely view x3550 text
messages over serial or LAN. An optional upgrade to the Virtual Media Key adds graphical
console redirection.
Predictive Failure Analysis (PFA) is designed to allow the system to detect impending failure of
supported components (memory, power supplies, hard disk drives, and fans) before actual
failure, and alert the administrator through IBM Systems Director. This gives you the ability to
replace the failing component before it fails, resulting in increased uptime.
IBM Systems Director software for advanced workgroup management is included with the
x3550 M2. IBM Systems Director comes with a portfolio of tools, including Management
Processor Assistant, Rack Manager, RAID Manager, Update Assistant and Software Distribution.
Systems Director Active Energy Manager for x86, System Availability (a no-charge download)
and Capacity Manager (sold separately) are available as add-ons for additional server
management and increased availability. IBM Systems Director provides a single uniform
graphical interface for all of these systems management functions.
IBM Systems Director enables you to customize thresholds and monitor system components (for
things like temperature, voltage regulation, etc.) to help maximize uptime.

Leadership enterprise server with significantly lower cost of ownership in a highly available and
expandable, rack-dense, 1U dual-socket server
lets you keep your fingers on the pulse of your e-business.
Processors — The Intel Xeon processor provides high clock rates, dual- or quad-cores, 64-bit
extensions, a large cache and advanced features for availability and manageability. Large cache
size, combined with a fast 1333MHz or 1066MHz front-side bus, reduces memory latency and
facilitates the movement of data through the processor and I/O devices. (Note: System
performance depends not only on the number of processors in the server but also on the power
and functionality of each processor.) Adding a second processor may be a cost-effective way to
achieve significant performance improvements.
Memory — Memory is a significant factor in systems application performance. Adding more
memory to a System x server is one of the most effective ways to increase application
performance. For best performance in a server with a dual-core processor, there should be twice
as much memory available as for a single-core processor.
Hard Disk Drives — IBM hard disk drives help you improve the transaction and cost
performance of your System x servers. The choice of hard disk drives can be a critical aspect of
maximizing the I/O throughput of the system. SAS hard disk drives are available for the x3550
M2 with capacities up to 300GB (2.5-inch) apiece at 10,000 RPMs, up to 146.8GB (2.5-inch)
apiece up to 15,000 RPMs, or up to 73.4GB apiece (2.5-inch) at 15,000 RPM.
Power Supply — The optional second power supply for the x3550 M2 enables redundancy for
hot-swap power.
Virtual Media Key — The x3550 M2 includes a plethora of systems management features built-
in; however, sometimes additional management capability is needed. In those situations, the
Virtual Media Key not only offers powerful new features, it does so without taking up a valuable
PCI-X or PCIe adapter slot, instead using a dedicated slot on the motherboard.
ServeRAID Controllers — System x servers using ServeRAID BR10i technology allow
companies to build a reliable foundation for business-critical computing. IBM ServeRAID
technology allows an array consisting of multiple physical hard disk drives to be treated as one
logical drive. ServeRAID technology also allows data to be stored redundantly, across multiple
hard disk drives— enhancing both the integrity and the availability of the data. SAS and SATA
ServeRAID controllers offer enhanced performance due to onboard processors and cache.
Because IBM ServeRAID controllers can help significantly improve data transfer rates, this
technology is extremely effective when implementing demanding, transaction-oriented
applications. By employing the advanced fault tolerance of IBM ServeRAID technology,
companies can effectively implement networked business systems that require large amounts of
storage space for data and applications that must be available for their businesses to continue
operating.
The optional MegaRAID-MR10i SAS/SATA controller offers enhanced performance over the
integrated ServeRAID BR10i l controller (SAS models), 256MB of battery-backed cache memory,
and supports six RAID levels: 0 (striping), 1 (mirroring), 10 (mirroring and striping), 1E (enhanced
mirroring, supporting odd numbers of drives), 5 (striping with parity), and 6 (striping with double
parity).
The optional MegaRAID MR10is supports hardware based full disk encryption plus RAID-
0/1/10/1E/5/6 support.
The optional MegaRAID MR10M SAS controller offers high performance and 256MB of cache
memory (with optional battery backup) for external SAS storage capacity. The adapter supports
five RAID levels: 0 (striping), 1 (mirroring), 10 (mirroring and striping), 5 (striping with parity), and
50 (striping/mirroring with parity).
External Storage — The IBM System Storage DS3000, DS4000, DS6000, and DS8000 series,
as well as the N3000, N5000, and N7000 series, comprise a powerful and broad shared storage
family with integrated management software designed to meet midrange and enterprise needs.
For lower-end needs, IBM offers the System Storage DS400 storage enclosure.
External SAN, iSCSI, and direct-attach storage is available using one of several IBM System
Storage and TotalStorage host bus adapters. Additionally, external LAN-attached tape storage is
available.
The iSCSI HBA Adapter for IXA Connectivity is a PCI adapter for selected System x servers
that provides a direct 1GBps link to an IBM System i5 server. This connection enables you to
centralize your Microsoft Windows and System i5 storage and consolidate the operations and
backup of your System x, and System i5 systems into a single infrastructure. It enables the
tightest possible integration between Windows and System i5/iSeries data and applications, and
allows as many as 32 servers to attach to one System i5 system to share the iSeries server’s
systems management, DVD, tape and disk storage via the iSeries dynamic virtual storage
architecture. This can take the place of a SAN if you have an established System i5
infrastructure.

storage capacity. Accessible capacity is less; up to 3GB is
used in service partition. Actual storage capacity will vary
based upon many factors and may be less than stated.
Performance is in Internal Throughput Rate (ITR) ratio based
on measurements and projections using standard IBM
benchmarks in a controlled environment. The actual
throughput that any user will experience will depend on
considerations such as the amount of multiprogramming in the
user’s job stream, the I/O configuration, the storage
configuration and the workload processed. Therefore, no
assurance can be given that an individual user will achieve
throughput improvements equivalent to the performance ratios
stated here.

Maximum internal hard disk and memory capacities may
require the replacement of any standard hard drives and/or
memory and the population of all hard disk bays and memory
slots with the largest currently supported drives available.
When referring to variable speed CD-ROMs, CD-Rs, CD-RWs
and DVDs, actual playback speed will vary and is often less
than the maximum possible.
