Introducing Extended Fabric
Extended Fabric uses Fibre Channel technology to create a fabric interconnected
at a distance of up to 100 kilometers. Extended Fabric can increase the allowable
distance between two switches. It is an optionally licensed product that runs on:
■StorageWorks 1 Gb SAN switch series with StorageWorks Fabric OS version
2.0.x installed,
■StorageWorks 2 Gb SAN switch series with StorageWorks Fabric OS version
3.0.x installed,
■HP StorageWorks SAN Switch 2/32 with StorageWorks Fabric OS version
4.0.x installed, or
■HP StorageWorks Core Switch 2/64 (Core Switch 2/64) switches with
StorageWorks Fabric OS version 4.0.x installed.
Extended Fabric optimizes the internal buffering algorithm for StorageWorks
1 Gb SAN switches, StorageWorks 2 Gb SAN switches, and Core Switch 2/64
switches. Extended Fabric provides maximum buffering between E_Ports
connected over an extended distance. Buffer reconfiguration results in line speed
performance of close to full Fibre Channel speed for switches interconnected at
100 kilometers, thus providing the highest possible performance for transfers
between switches. The Fibre Channel connection extensions can be provided by
Extended Distance small form factor pluggables (SFPs), Fibre Channel repeaters,
or Wave Division Multiplexing (WDM) devices.
Note: Performance may vary depending on the condition of the fiber optic connections
between the switches. Losses due to splicing, connectors, tight bends, and other
degradation can affect the performance over the link and the maximum transmission
distance.

Extended Fabric Licensing
To enable Extended Fabric, an Extended Fabric license must be installed. If a
fabric is created with StorageWorks 2 Gb SAN switches or above, the long
distance extended fabric configuration has to be set only once for each fabric at
the edge port connector switch. The edge port connector switch automatically
works with the rest of the switches in the fabric.
Note: To enable Extended Fabric in a fabric created with StorageWorks 1 Gb SAN
switches, each switch in the fabric must be configured individually.

Installing Extended Fabric
The installation of Extended Fabric requires an Extended Fabric license on each
switch in the fabric. A license may have been installed in the switch at the factory.
If not, follow the procedure below to obtain a license key.
This chapter provides the following information:

Verifying Activated Licenses
You can display the current licenses using the licenseshow command. To
verify activated licenses:
1. Open a telnet or serial connection to the switch.
2. Log into the switch as Admin. The default password is password.
3. Enter the licenseshow command.

Activating the License Using Web Tools
To activate an Extended Fabrics license using Web Tools:
1. Launch a web browser by entering the switch name or IP address in the
Location/Address field of the browser and click Enter.
Web Tools launches, displaying the Fabric View.
2. Click the Admin button on the relevant switch panel.
The logon window displays.
3. Enter a login name and password with administrative privileges. The
administrator account user name and default password is “admin” and
“password”.
4. Click Enter.
The Administration View displays.
5. Select the License tab.
6. Enter the license key in the License Key field exactly as provided by your
switch supplier, and click Add.
The Extended Fabrics features are available as soon as the license is added.
For more information about Web Tools, refer to the HP StorageWorks Web
Tools Version 3.1.x/4.1.x User Guide.

Activating the License Using Telnet
Activate licenses using the licenseadd command. To activate an Extended
Fabrics license using the CLI:
1. Open a telnet or serial connection to the switch.
2. Log into the switch as Admin. The default password is “password”.
3. Contact the switch supplier for an Extended Fabrics license key.
4. Enter the following:
licenseadd “key”
where ”key” is the license key exactly as provided by the switch supplier.
The license key is case-sensitive.
switch:admin> licenseadd "aAaaaaAaAaAaAaA"
adding license key "aAaaaaAaAaAaAaA"
done.

Obtaining Optional Software License Keys from HP
If you’ve purchased optional software, or need to reinstall software features due to
a motherboard replacement in your switch, you will need to retrieve the software
license keys from the HP Authorization Center.
Obtain software license keys as follows:
■If you have your HP Registration Number, (located on your software
entitlement certificate) go to
http://webkey.external.hp.com/welcome.asp .
■If your HP Registration Number is unavailable, contact the Authorization
Center directly:
— Canada and United States, (Monday through Friday 6:00 am to 6:00 pm
MST), [phone] or [phone].
— Asia, (Monday through Friday 9:00 am to 5:00 pm), [phone]
or [phone].

Configuring an Extended
Fabric Connection
The Extended Fabric feature achieves long distance connections by allocating
more frame buffers for Fibre Channel traffic. Long distance connections require
more frame buffers than regular ISL connections. The greater the distance level of
a ISL long distance connection, the more frame buffers are required. This affects
the amount of buffers left over in the quad. A quad is defined as a group of four
adjacent ports that share a common pool of frame buffers. In an HP StorageWorks
SAN Switch (or port card in the Core Switch 2/64), ports 0 through 3 belong to a
single quad, ports 4 through 7 belong to a single quad, and so on.
Since the total number of frame buffers is limited in a quad when one port in a
quad is configured as a long distance port, all remaining ports in the same quad
must be configured appropriately. Refer to the “Long Distance Port Matrix” on
page 27.
Configuring long distance connections between core switches impacts available
ISL ports because normal ISLs are required for connections from core switches to
edge switches. When configuring long distance ISLs, make sure to balance the
need between long distance ISL connections and core-to-edge ISL connections
within a switch. Configuring long distance ISLs between core and edge switches
is possible, but is not a recommended practice.

Configuring an Extended Fabric Connection
20 Extended Fabric Version 3.1.x/4.1.x User Guide
Long Distance Configuration
Note: Only active GBICs should be used when using HP Extended Fabric.
Note: Trunking is not supported with LE, L1, and L2 modes.
The long distance extended fabrics configuration needs to be set only once for
each fabric at the edge switch E-port. The configuration should be between any
same series switch. Long distance ports consume more buffers than regular ISL
ports, which means that a long distance port could disable other ports in the same
quad due to lack of buffers. Refer to the “Long Distance Port Matrix” on page 27
for buffer credit information.
