Overview

The Hewlett-Packard SureStore E hub, short-wave model S10 and long-wave model L10, is

a full-duplex, 1063-megabit-per-second hub. It increases loop reliability, number of loop

connections, and distances between server and mass storage devices in a Fibre Channel

Arbitrated Loop. The hub’s port detection and bypass circuitry dynamically detects and

bypasses a failed node on the loop. Nodes can be added, removed, and reconnected

without bringing down the loop and disrupting communication for other nodes.

Fibre Channel Manager is a web-based software application that allows you to remotely

manage and monitor the health of the hub. To learn more about Fibre Channel Manager,

visit the Hewlett-Packard (Software Depot (http://www.software.hp.com). Fibre Channel

Manager is available as a free download from this web site.

Older hubs may require a firmware upgrade to meet Fibre Channel Manager’s minimum

requirements. The Software Depot web site has more information about this. The latest

hub firmware and upgrade instructions are available as a free download from this web site.

Detailed configuration information and part numbers for the hub are provided in chapter 6,

Reference.

Features

HP SureStore E hubs provide the following features:

•

Short-wave hub (model S10): 10 non-Open Fibre Control (non-OFC) short-wave

optical transceivers

Long-wave hub (model L10): nine non-OFC, short-wave optical transceivers and one

non-OFC, long-wave optical transceiver

Local retime and regeneration of transmit signals to prevent accumulation of jitter and

improve the signal

Reliable, automatic bypass of failed nodes; dynamic recognition of newly added or

removed nodes, with a controller in each port permitting the bypass of a port if the port

fails signal validity tests

•

Active loop reconfiguration when a node to an arbitrated loop is added, removed, or

moved

Plug-and-play capability, which allows the hub to connect to compatible servers and

other Fibre Channel Arbitrated Loop (FC-AL) devices while they are operating ( FC-AL

devices can be added or removed while the hub is active.)

•

Cascade support (hub-to-hub connections) for increased loop distances

Cascaded short-wave hubs are supported up to 500 meters; cascaded long-wave hubs

are supported up to 3000 meters (3 km). Under certain conditions, cascaded long-wave

hubs are supported up to 10,000 meters (10 km) (see page 105 for more information).

The 10-km capability only applies to long-wave hubs connected to HP-UX servers.

Note

Increased loop distances are associated with increased latency times.

•

Access to the RS-232 interface for firmware upgrades and hub configuration and

troubleshooting

Support for a hub management tool (Fibre Channel Manager) to remotely manage and

monitor the health of the hub

Front Panel, Model S10 Short-Wave Hub

The front panel contains LEDs for monitoring power, fault, and port status. The RS-232

port is provided to configure and troubleshoot the hub and to upgrade its firmware. The

10Base-T port provides an ethernet connection if you choose to manage the hub with Fibre

Channel Manager.

The Reset button resets the internal control microprocessor of the hub. Pushing the Reset

button also forces loop initialization on all devices in the loop.

troubleshoot the hub and to upgrade its firmware. The 10Base-T port provides an ethernet

connection if you choose to manage the hub with Fibre Channel Manager.

The Reset button resets the internal control microprocessor of the hub. Pushing the Reset

button also forces loop initialization on all devices in the loop.

Supported Topologies

Devices such as FC-AL disk arrays and HP system servers that support FC-AL can be

connected to the hub in a loop that includes one or more servers. All nodes in the loop

must be 1063 Mbps short-wave, non-OFC, FC-AL. The ports connected by a cable must

have the same optical transceivers. Figure 4, Figure 5, and Figure 6 show typical hub

topologies. For details on supported topologies, contact an HP sales representative.

Single Short-Wave Hub Topology

For the model S10 short-wave hub, Hewlett-Packard recommends 50-micron multimode

fiber cable for new installations, but also supports 62.5-micron multimode fiber cable with

SC-style connectors in existing installations. Stated distances assume 50-micron multimode

cable.

A server with an FC-AL short-wave adapter can connect to an hub 500 meters away. Each

of the 10 ports on the short-wave hub can connect to an FC-AL device up to 500 meters

away. The maximum distance between the server and the end FC-AL device is 1000 meters

(1 km).

Cascaded Short-Wave Hub Topology

The example in Figure 5 shows two model S10 hubs connected in a cascade topology.

Cascaded short-wave hubs use one port on each hub for the hub-to-hub connection. Such a

configuration increases the potential distance between nodes in the loop an additional 500

meters. The maximum distance between the server and FC-AL devices with cascaded

short-wave hubs is 1500 meters (1.5 km).

Cascaded Long-Wave Hub Topology

Cascaded FC-AL, non-OFC, model L10 long-wave hubs use the long-wave port for the hub-

to-hub connection. The maximum supported distance between cascaded long-wave hubs

with single-mode 9 micron cable is 3 km. The maximum distance between a server and FC-

AL devices on cascaded long-wave hubs is, therefore, 4000 meters (500 m + 3000 m +

500 m). Under certain conditions, cascaded long-wave hubs are supported up to 10,000

meters (10 km) (see page 105 for more information). The 10-km capability only applies to

long-wave hubs connected to HP-UX servers.

Caution

When cascading long-wave hubs, only connect long-wave ports to long-wave

ports or short-wave ports to short-wave ports.

Ports 1 through 9 on each long-wave hub are for connections to FC-AL devices. Ports 1

through 9 can also be used in a cascaded configuration; however, the maximum distance

between hubs decreases from 3000 meters to 500 meters.

Procedure 3: Verify Hub Operation

By performing this procedure, you test the hub and verify that it operates properly before

you mount it in a rack or connect any devices to it.

1. To initialize the self-test, first plug the power cord into the hub and then into a power

receptacle. The hub does not have a power switch.

The hub runs the self-test each time the power cord is plugged in or the Reset button is

pressed.

Note

The hub’s power supply automatically adjusts to a range of 100 VAC ±10% or

240 VAC ±10%.

2. The hub finishes the self-test in less than 15 seconds.

If the Fault LED (amber) stays on after self-test, the hub failed. Refer to chapter 4,

Troubleshooting, or contact an HP service representative for assistance.

If the Power LED does not light, refer to chapter 4, Troubleshooting, or contact an HP

service representative.

Note

Interruptions to the hub’s AC power source initiate a self-test. Make sure the

power source circuits are properly grounded before using the supplied power

cord to connect the hub to the circuit.

3. Verify that each Fibre Channel port is operating properly. Insert the loopback cable into

the port and verify that the port status LED turns on. Both ends of the loopback cable

plug into the port connectors.

If you plan to use Fibre Channel Manager to manage the hub, continue with step 4. If you

do not plan to use Fibre Channel Manager or another hub management tool, go to step 7.

Procedure 3: Verify Hub Operation

4. Verify that the 10Base-T port is operating properly. Insert an ethernet cable that is

connected to the LAN into the 10Base-T port, and verify that the 10Base-T status LED

turns on. (The status LED may begin flashing.)

5. Set the hub IP address and configure the hub as described in chapter 3, RS-232 Interface

Functions.

6. Verify the connection between the HP-UX server and the hub. At the management server

where Fibre Channel Manager is or will be installed, execute the following command:

/etc/ping <hub IP address>

Example: /etc/ping 15.43.214.13

Fibre Channel Manager requires HP-UX 10.20 or 11.0 on the management server.

If you are unable to ping the hub, refer to If the Management Server Cannot Ping the

Hub on page 78.

7. Unplug the hub.

Procedure 3: Verify Hub Operation

Procedure 4: Mount the Hub into a Rack (Optional)

The hub mounts into any standard HP 19-inch wide EIA cabinet. The hub’s front panel will

face the rear of the cabinet. The front of the hub contains the 10 Fibre Channel connectors.

You will need a T25 Torx head screwdriver to complete this procedure.

1. Record the serial number, located on the bottom of the hub, and the MAC address,

located under the 10Base-T port. The MAC address is unique and cannot be changed.

2. Verify that the rack is adequately secured and has enough space (1 EIA) for the hub.

Remove filler panels as needed from the front of the cabinet and open the rear door.

3. If the rubber feet are attached to the bottom of the hub, peel off the feet. Attach the

mounting ear brackets and nylon retainers if they are missing from the left and right

sides of the hub (Figure 8).

Secure the mounting ear brackets with three M3 x .5 screws to each front outside

corner, turning the angled end of the bracket outward. Attach the nylon retainers with

one screw through the center of the retainer and into the hole in each side of the hub.

Procedure 5: Plan the FC-AL Connections

The hub does not require drivers or specific versions of operating systems. However,

systems and FC-AL devices that can connect to the hub do have driver and operating

system requirements. Contact an HP sales representative for information on hardware and

software requirements for the systems or FC-AL devices you plan to connect to the hub.

The HP Fibre Channel Manager User Manual lists operating system requirements for

Fibre Channel Manager.

1. Verify that the loop cabling configuration is correct by comparing it to the cabling

examples on the following pages. Modify the network cabling map as needed.

Caution

Incorrect wiring can lead to problems such as devices left off the loop and

inaccessible by the server. Follow the guidelines below before starting.

2. Refer to your cabling map to review the user-assigned loop ID (hardware address) of

each FC-AL device to be connected to the hub, and verify that each ID is unique.

Duplicate IDs on the loop can cause problems.

3. Verify that the connections between the hub port and the FC-AL mass storage device or

the FC-AL adapter are of the same wave type and speed. For example, plan to connect

a short-wave port on the hub to a short-wave port on an FC-AL device.

4. Document the planned connections in a cabling map.

Correct Cabling Example for a Short-Wave Hub

For the model S10 short-wave hub, Hewlett-Packard recommends 50-micron multimode

fiber cable for new installations but also supports 62.5-micron multimode fiber cable with

SC-style connectors in existing installations.

Procedure 5: Plan the FC-AL Connections

Download from Www.Somanuals.com. All Manuals Search And Download.

In a cascaded configuration of model S10 short-wave hubs, connect any port on the first

hub to any port on the second hub. Figure 13 includes all 18 nodes in the loop formed by

FC-AL Device 1, Hub A, Hub B, and FC-AL Device 2:

–

Port 1 on Hub A connects to FC-AL Device 1.

Port 10 of Hub A connects to Port 1 of Hub B.

Port 10 on Hub B connects to FC-AL Device 2.

In this configuration, any unused port on Hub A or Hub B can connect to any compatible

FC-AL device. This is just one example of cascaded short-wave hubs. The connection

between short-wave hubs can occupy any combination of ports.

Note

If you plan to use Fibre Channel Manager to manage cascaded hubs, you must

configure the hub that has the LAN (ethernet) connection as a parent hub and

the remaining hub as a child hub (see Configuring Cascaded Hubs on page 60).

Correct Cabling Example for a Long-Wave Hub

Hewlett-Packard recommends 9-micron, single-mode fiber cable for the long-wave port.

For ports 1 through 9, the short-wave ports, Hewlett-Packard recommends 50-micron

multimode fiber cable for new installations but also supports 62.5-micron multimode fiber

cable with SC-style connectors in existing installations.

Procedure 5: Plan the FC-AL Connections

Download from Www.Somanuals.com. All Manuals Search And Download.

In a cascaded configuration of FC-AL long-wave hubs, connect the long-wave port on the

first hub to the long-wave port on the second hub. Figure 14 shows all 18 nodes in the loop

formed by FC-AL Device 1, Hub A, Hub B, and FC-AL Device 2:

–

Port 1 on Hub A connects to FC-AL Device 1.

The long-wave port of Hub A connects to the long-wave port of Hub B.

Port 1 on Hub B connects to FC-AL Device 2.

Long-wave hubs can be cascaded with ports 1 through 9 (the short-wave ports), but the

supported distance between hubs is reduced from 3000 meters to 500 meters. When

cascading long-wave hubs, ONLY connect long-wave ports to long-wave ports or short-

wave ports to short-wave ports. Any unused short-wave port on Hub A or Hub B can

connect to any compatible FC-AL device.

Procedure 6: Connect FC-AL Devices

After the hub and devices are prepared, connect FC-AL devices as follows:

1. Physically set each FC-AL device to a unique loop ID (hardware address). Refer to the

FC-AL device’s manual to set the loop ID.

If devices are added during normal operation and duplicate IDs occur, the Fibre

Channel driver denies access to both devices until the address conflict is resolved.

Change the address of the second (duplicating) device.

If devices are added or device addresses changed while the system is powered off

and duplicate IDs occur, the system is unavailable until the address conflict is resolved.

An error message appears on the system console. Change the address of the second

(duplicating) device.

2. Remove the covers from the FC-AL ports. Refer to your cabling map, and begin

connecting devices to the hub. Leave the covers on ports not in use.

Caution

Fiber optic cables and connectors are extremely fragile. Avoid twisting or

bending the cable beyond a 3-cm radius.

If the hub and all FC-AL devices are powered down, first plug in the hub, then

power on the devices at all the FC-AL nodes on the loop. The hub should be the first

operating component in the loop.

If the hub and all devices are powered up, you can connect the hub to a server or

FC-AL device while the server or FC-AL device is operating.

Procedure 6: Connect FC-AL Devices

Download from Www.Somanuals.com. All Manuals Search And Download.

If the hub is to be connected to an FC-AL adapter that is connected to another FC-AL

device, follow the removal procedures in the document that came with the FC-AL

device before disconnecting the device’s cable.

If the hub is to be connected to an FC-AL device that is connected directly to a server,

follow the removal procedures in the document that came with the FC-AL device

before disconnecting the device’s cable.

When installing model L10 long-wave hubs in a cascaded topology, make sure the

long-wave port is connected only to the long-wave port on another long-wave hub.

3. For the model L10 long-wave hub, connect the long-wave loopback cable to the

long-wave port if the port is not in use.

4. Install any special files the FC-AL devices need. Refer to the device manual for details.

Procedure 6: Connect FC-AL Devices

Download from Www.Somanuals.com. All Manuals Search And Download.

Procedure 7: Verify the Connections

After connecting devices and the server to the hub, verify the connections.

Note

Because the hub is strictly a pass-through device for FC-AL traffic, there is no

hub address and the hub is not listed in ioscan output (HP-UX servers) or the

SCSI Adapters window (HP NetServers).

For HP-UX servers:

1. Use the following HP-UX command to run ioscan and check the hardware paths

between the server and the attached FC-AL devices:

ioscan -f

For details on ioscan and its options, refer to the HP-UX System Administration

Tasks Manual. Also consult the device documentation to interpret the ioscan output.

2. If the Hardware State of a device connected to the hub is “Unclaimed” or “No H/W,” see

chapter 4, Troubleshooting, for more information.

For HP NetServers:

1. From the Start menu, select Settings, then select Control Panel.

2. Double-click the SCSI Adapters icon. The SCSI Adapters window appears.

3. Click the Devices tab, then verify that the FC-AL devices connected to the hub are

displayed.

Updating the Hub Firmware

The hub’s management tool, Fibre Channel Manager, requires the following versions of hub

firmware: .

Device Agent

Hub Controller

02.14 (or higher)

03.06 (or higher)

Before you begin this procedure, determine whether the hub requires a firmware update to

communicate with Fibre Channel Manager. A label on the bottom of the hub chassis lists

the EDC datecode. If the EDC datecode is C-38XX or higher, the hub has the required

firmware.If you are not able to access the label, determine the firmware versions by

connecting to the hub’s RS-232 interface (see Setting Up an RS-232 Connection on page 45).

To update the hub firmware, use a PC connected to the hub. First copy the firmware files to

the PC and then transfer the firmware from the PC to the hub.

The general process for updating the hub firmware is the following:

1. Obtain the current firmware.

2. Reboot the hub.

3. Update the hub controller firmware.

4. Update the hub device agent code.

5. Reset the hub.

6. Set manufacturing values.

If any hubs are cascaded, repeat the procedures for each child hub. Parent and child hubs

must have identical versions of the firmware.

The procedures in this section require a total of 30 to 60 minutes to complete.

Troubleshooting Procedures

If there is a problem accessing a device connected to the hub, the source of the problem

can be with the device, the hub, the host, or any of the connections between the host and

the device. Follow the steps below to investigate the problem from the most likely to the

least likely cause. In addition, check the troubleshooting tables in this chapter for solutions

to specific symptoms.

1. For HP-UX servers, run ioscan from the server’s console.

–

If the hardware paths for all FC-AL devices connected to the hub are listed in ioscan,

the connection from the host to the device is good, and problems accessing a device

probably originate in the software, driver, or device.

If the hardware path for a FC-AL device connected to the hub is not listed in ioscan,

the source of the problem is likely to be bad connections, duplicate hardware

addresses, a faulty device, or a faulty hub (see steps 2 through 5). The hub does not

appear in ioscan output because it does not have a hardware address.

For HP NetServers, open the SCSI Adapters window, then click the Devices tab. If

the device is not displayed, the problem is likely to be bad connections, duplicate

hardware addresses, a faulty device, or a faulty hub (see steps 2 through 5). The hub

does not appear in this window because it does not have a hardware address.

2. Inspect the cabling between the hub and FC-AL devices. Check for loose, dirty,

broken, or bent cabling and connectors. Cables should attach with an audible click.

3. Check the loop ID (hardware address) of each device on the loop and eliminate

any duplicate addresses. Reset the hub after changing any loop ID, then run ioscan to

make sure there are no duplicate addresses. Duplicate addresses can be indicated by

“NO H/W” in the S/W State field.

4. Inspect the FC-AL device for a fault. Follow the instructions that came with the

device. Make sure you check the fiber optic transmit or receiving port on the device.

5. Inspect the hub LED indicators for apparent problems (see Table 2 on page 70). If

the Fault LED is lit, either the fans or the hub is faulty. If a cable is connected to a port

Introduction

This chapter explains how to maintain the hub and replace the fan module. The fan module

is the only replaceable part on the hub. To identify the source of a problem, see chapter 4,

Troubleshooting.

WARNING

Do not attempt to open the hub chassis. Uninsulated parts inside the

chassis constitute a hazard.

Introduction

Download from Www.Somanuals.com. All Manuals Search And Download.

Maintenance

Good system performance requires clean port optics and cable ferrules to avoid

obstructing the optical path. The following preventive maintenance will protect the hub for

longer use.

•

Vacuum to remove dust.

Leave the FC port covers on unused FC ports.

Replace the fan module every three years.

Avoid dropping fiber optic cable ends. This can cause internal glass fractures and

intermittent signals.

•

Keep unused cable ends covered to avoid contaminant-obscured or attenuated light

signals.

•

Never insert foreign objects into the optical transmit and receive ports.

Avoid bending fiber cables over more than a 3-cm bend radius.

When a faulty connection is suspected, blowing clean compressed air on the FC port and

cable end often is sufficient to remove dirt particles. Cleaning the connectors with

methanol on a lint-free cloth is also effective. Alcohols that can be used include methyl,

isopropyl, and isobutyl. Other acceptable substances for cleaning fiber optics are hexane

and heptane aliphatics, soap solution, and naphtha.

Caution

DO NOT use partially halogenated hydrocarbons, ketones, acetone,

chloroform, ethyl acetate, methylene dichloride, phenol, methylene chloride, or

N-methylpyrolldone to clean the connectors.

Maintenance

Replacing the Fan Module

The three fans in the fan module operate in parallel. If one fan fails, the other two will

continue to operate. However, it is important to replace the fan module immediately.

Replace the fan module at least once every three years.

You will need the following tools:

•

Standard Phillips screwdriver

Fan module (A3724-60002)

WARNING

The power cord is the main disconnect for this product. To protect

against hazard, always unplug the AC power cord before removing

the fan module.

1. Relocate or power off devices connected to the hub as needed to prepare for powering

off the hub.

2. Unplug the power cord from the hub.

3. Using a standard Phillips screwdriver, remove the four screws that secure the fan

module. Sheet metal marks indicate the location of the screws on the top and sides of

the hub.

Operating Requirements

Software and Operating System Requirements

The hub does not require drivers or specific versions of operating systems. However,

systems and FC-AL devices that can connect to the hub do have driver and operating

system requirements. Contact an HP sales representative for information on hardware and

software requirements for the FC-AL devices you plan to connect to the hub.

Physical and Cabling Requirements

Note

For short-wave ports, SC Connectors must be AMP multimode #504657-1 or

equivalent to meet FCC Part 15 standards. For long-wave ports, SC Connectors

must be AMP single-mode #504655-1 or equivalent to meet FCC Part 15

standards. Cable Plant Specifications on page 101 lists more requirements.

Model S10 Short-Wave Hub

The short-wave hub supports 10 non-OFC, short-wave FC-AL connections. In arbitrated

loop topology, data rates and wavelength between ports must be the same. The short-wave

hub supports only gigabit short-wave to gigabit short-wave connections using fiber cables.

For the short-wave hub, Hewlett-Packard recommends 50-micron multimode fiber cable

for new installations but also supports 62.5-micron multimode fiber cable with SC-style

connectors in existing installations. Installations can mix 50-micron and 62.5-micron

cables.

Model L10 Long-Wave Hub

For the long-wave port, Hewlett-Packard recommends 9-micron single-mode fiber

cable.

For ports 1 through 9, Hewlett-Packard recommends 50-micron multimode fiber cable

for new installations but also supports 62.5-micron multimode fiber cable with SC-style

connectors in existing installations.

Cable Plant Specifications

The cable plant includes losses of the fiber and splices and connectors (excluding those at

the ends of the link that are accounted for in the transmitter and receiver specifications).

HP suggests that the loss of a new single-mode cable plant be limited to 6dB or lower in

order to maximize the probability that the cable plant will permit 10- km operation with

the majority of long-wave hubs (HP-UX servers only). Larger losses are permissible if the

receiver power is greater than -17dBm. For new installations, HP recommends that the

single-mode fiber be low-loss fiber equivalent to Corning’s premium grade of their single-

mode SMF-28 cable with loss of 0.35 dB/km or lower in order to more easily attain the

required signal power at the receiver in spite of losses due to connectors and splices.

Model L10 Long-Wave Hub

Note

Stated distances assume 9-micron single-mode cable for the long-wave port and

50-micron multimode cable for the short-wave ports.

For ports 1 through 9, the long-wave hub supports distances of 500 meters between the

port and a connected FC-AL device. For the long-wave port, the long-wave hub supports

distances up to 3 kilometers between two long-wave hubs. Under certain conditions,

cascaded long-wave hubs are supported at distances up to 10 kilometers. The 10-km

capability is supported only for long-wave hubs connected to HP-UX servers.

To verify 10-km capability for the long-wave hub over an existing cable plant:

The received average optical power of the long-wave port on both long-wave hubs must be

higher (more positive) than -17 dBm in order for the long-wave hubs to support cascade

distances of up to 10 km. Use an optical power meter that measures average optical power

at a wavelength of 1300 nm in dBm units (for example, the Fotec Model 712A Power Meter

with Model A262 SC connector adapter).

To verify the long-wave port’s received average optical power, do the following:

1. Power on both long-wave hubs and connect the long-wave ports with the 10-km single-

mode cable.

2. Turn the optical power meter on. The meter performs a self-test.

3. If necessary, set the meter’s wavelength to 1300 nm and measuring units to dBm.

4. Disconnect the Fibre Channel cable from the long-wave port of one of the two hubs.

5. Determine which connector of the Fibre Channel cable is the transmitter. Connect one

plug of the Fibre Channel cable into the SC receptacle of the meter. If the meter does

not indicate a signal, connect the other plug of the Fibre Channel cable.

6. Verify that the reading on the meter is higher (more positive) than -17 dBm and lower

than -3 dBm.

7. Reconnect the Fibre Channel cable to the long-wave port.

8. Repeat steps 4 through 7 with the long-wave port of the second long-wave hub.

If both ends of the Fibre Channel cable are between the limits listed in step 5, the two

long-wave hub’s are verified for cascading up to 10 km using this cable plant. If the meter

readings are not within range, verify that the Fibre Channel cable is securely connected to

the hub’s long-wave port. Also verify, that the cable connectors are clean by wiping them

with a lint-free cloth dampened with reagent grade isopropyl alcohol and blowing the

connectors dry with clean, compressed air.

GLOSSARY

Arbitrated Loop

See Fibre Channel - Arbitrated Loop.

Child Hub

The HP SureStore E short-wave and long-wave hubs support a cascaded topology. In a

cascaded hub topology, the child hub is the hub that is not connected to the LAN

(ethernet). HP SureStore E hubs are configured as a parent or child hub through their

RS-232 interface.

Device

See FC-AL Device.

Enclosure

The box, rack, or set of boxes containing one or more devices. It may provide the

powering, cooling, mechanical support, and external electronic interfaces for those

devices.

FC-AL Device

A device that uses Fibre Channel Arbitrated Loop, which consists of one or more

NL_Ports.

FC-AL Port

The port on the hub that provides connection between the FC-AL adapter and the FC-

AL link.

Fiber

The fiber optic cable made from thin strands of glass through which data in the form of

light pulses is transmitted (LASER, LED). It is used for high-speed transmission over

medium to long distances.

Fibre Channel

Logically, Fibre Channel is a bidirectional, full-duplex, point-to-point, serial data

channel structured for high performance capability. Physically, the Fibre Channel is an

interconnection of multiple communication ports, called NL_Ports, interconnected by a

switching network, called a fabric, a point-to-point link or an arbitrated loop. Fibre

Channel is a generalized transport mechanism that has no protocol of its own or native

input/output command set, but can transport any existing Upper Level Protocols

(ULPs) such as SCSI and IPI at speeds of 100 Mbytes/sec over distances of up to 10

kilometers over optical links. Fibre Channel can interconnect two devices in a point-to-

point topology, from two to 126 devices in an arbitrated loop, and up to 224 devices in a

fabric switched topology.

Fibre Channel Arbitrated Loop (FC-AL)

One of three existing Fibre Channel topologies in which two to 126 devices are

interconnected serially in a single loop circuit without hubs and switches.

Communication is managed using an arbitration process in which the lowest port

address has the highest priority for communicating. The arbitrated loop topology

supports all classes of service and guarantees in-order delivery of frames when the

source and destination are on the same loop.

Link

For Fibre Channel, a connection between two nodes, each having at least one N_Port,

interconnected by a pair of optical or copper links, one inbound and one outbound.

Long Wave

Lasers or LEDs that emit light with wave lengths around 1300 nm. Long-wave lasers are

used for long Fibre Channel links, from 700 to 2000 meters. They are typically used with

single-mode fiber of a 9-micron core size.

Loop Address

The unique ID of a node in Fibre Channel loop topology, sometimes referred to as a loop

ID.

118

Glossary

Download from Www.Somanuals.com. All Manuals Search And Download.

N_Port

A “Node” port. A Fiber Channel-defined hardware entity that performs data

communication over the FC-AL link. It is identifiable by a unique World Wide Name. It

can act as an originator or a responder.

N_Port Identifier

A unique address identifier by which an N_Port is uniquely known. It consists of a

Domain (most significant byte), an Area, and a Port, each 1-byte long. The N_Port

identifier is used in the Source Identifier (S_ID) and Destination Identifier (D_ID) fields

of an FC-AL frame.

Parent Hub

The HP SureStore E short-wave and long-wave hubs support a cascaded topology. In a

cascaded hub topology, the parent hub is the hub that is connected to the LAN

(ethernet). HP SureStore E hubs are configured as a parent or child hub through their

RS-232 interface.

Short Wave

Lasers or LEDs that emit light with wave lengths around 780 nm or 850 nm. Short-wave

lasers are used for FC-AL links up to approximately 700 meters. They are typically used

with multimode fiber. The preferred fiber core size is 50 micron because this fiber has

large bandwidth so that the distance is limited by the fiber attenuation. A 62.5-micron

core size is also supported for compatibility with existing FDDI installations. Fiber of

this type has smaller bandwidth and, in this case, the distance is limited by the fiber

bandwidth.

Topology

The physical or logical layout of nodes on a network. FC-AL topologies include point-to-

point, FC-AL, and fabric. The hub supports FC-AL topology.
