Supported Configurations
8Edge Switch Release Notes
Supported Configurations
Operation of multiple switches in a fabric topology is subject to the following
topology limits. Consider the impact of these limits when planning the fabric.
Note: For more information about planning the fabric, refer to HP StorageWorks SAN
High Availability Planning Guide
.
■Fabric Elements – Each fabric element is defined by a unique domain ID that
ranges between 1 and 31; therefore, the theoretical limit of interconnected
switches in a single fabric is 31. The supported limit of interconnected
switches in a single fabric is 24. Because this number is subject to change,
contact your HP authorized service representative for the current number of
interconnected switches supported in a single fabric.
■Inhomogeneous fabric – To determine if interoperability is supported for a
product, or if restrictions apply, refer to the product publications, or contact
your HP authorized service representative.
■Number of Interswitch Links (ISLs) – The maximum supported number of
ISLs for edge switches is all available switch ports. For redundancy, at least
two ISLs should connect any two switch-class fabric elements. Because this
number is subject to change, contact your HP authorized service
representative for the current number of ISLs supported per switch.
■Hop Count – The Fibre Channel theoretical limit of ISL connections
traversed (hop count) in a single path through a fabric is 7. The maximum
supported hop count in a single path through a fabric is 3. Because this
number is subject to change, contact your HP authorized service
representative for the current hop count supported by a single fabric path.
Note: The hop count is equal to the number of ISL connections traversed in a single
path, not the total number of ISL connections between devices.

Cable Requirements
9Edge Switch Release Notes
Cable Requirements
Note: Please note that optical cables for the Edge Switch 2/24 and Edge Switch 2/32
must be ordered separately.
For cables measuring up to 500 meters (1 Gbps) or 300 meters (2 Gbps), use
multi-mode Fibre Channel cables. For longer cables, use single-mode Fibre
Channel cables.
Multi-mode optical cables are connected to short-wave optical transceiver
modules in a switch. Single-mode optical cables are connected to long-wave
optical transceiver modules in a switch. Multi-mode cables should use 50/125
optical fibers, and single-mode cables typically use 9/125 optical fibers for
distances up to 10 km.
Verify that connectors interfacing with the Edge Switch 2/24 and Edge
Switch 2/32 use LC Duplex connectors with a PC finish. In addition, the
connector at the opposite end of the cable must use either LC or SC type,
depending on the requirements of the connected device.

Important Information
10 Edge Switch Release Notes
Important Information
This section describes important information related to the Edge Switch 2/24 and
Edge Switch 2/32.
HAFM and Firmware Version Compatibility
Table 1 lists the minimum version of HAFM that can run with the various versions
of firmware for the directors and edge switches.
Upgrading to an Earlier Version of Firmware
Upgrading to firmware version 05.01.00-24 is nondisruptive to attached devices.
The edge switch or director is not required to be offline before performing an
upgrade operation. Limitations to upgrades are clearly identified if there are any
limitations to performing the operation.
Before upgrading firmware, it is highly recommended that you back up the edge
switch or director configuration in the event that a failure should occur. Refer to
the switch or director Product Manager user guide for more information.
Embedded Web Server (EWS) also provides an option to print or save product
configuration to a file. Refer to the HP StorageWorks Embedded Web Server User
Guide for more information.
Before upgrading the Director 2/64 or Director 2/140 to version 05.01.00-24,
execute a CTP switchover to assure that the backup CTP card is fully functional.
