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 seven. The maximum
supported hop count in a single path through a fabric is three. 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
Note: Optical cables for the Edge Switch 2/12, Edge Switch 2/12, 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 2/12, 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 be of either LC or SC type,
depending on the requirements of the connected device.
Important information
This section describes important information related to the Edge Switch 2/12,
Edge Switch 2/24, and Edge Switch 2/32.
HAFM and firmware compatibility
Table 1 lists the minimum version of HAFM that can run with the various versions
of firmware for the directors and edge switches.

9HP StorageWorks Edge Switch release notes
Prerequisites for installing and using firmware 06.02.00
If you are using HAFM, firmware 06.02.00 requires HAFM 07.01.00 or later
(check with HP Customer Support for the latest shipping version of HAFM).
HAFM should be at the minimum level before installing the new firmware.
Note: HAFM is not required for operating hardware products using the firmware.
All directors and edge switches in the same fabric should have the same firmware
level installed. Although products may co-exist in a fabric running different levels
of firmware, all products must be at the same major functional release level.
Upgrading from an earlier version of firmware
Upgrading to firmware 06.02.00-22 is non-disruptive to attached devices. The
director or edge switch 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.

About this document
10 HP StorageWorks Edge Switch release notes
Before upgrading firmware, it is highly recommended that you back up the
director or edge switch configuration. Refer to your HP StorageWorks Edge
Switch Element 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.
All products must be running firmware 05.00.00 or later before upgrading to
06.02.00-22. If a switch is operating with a firmware level earlier than 05.00.00,
you must upgrade to 05.xx.xx before installing 06.02.00-22.
Upgrades and downgrades are supported only from one major release to the next,
such as from 05.xx.xx to 06.02.00-22. If EWS is used for upgrades and
downgrades, and this rule is not followed, errors occur and there may be a
disruption to attached devices.
If upgrading to firmware 06.02.00-22 requires you to upgrade from 04.xx.xx to
05.xx.xx in the process, there are special considerations, as detailed in the section,
“Upgrading firmware on an edge switch from 04.xx.xx to 05.xx.xx” on page 10.
A small number of early-shipped Surestore Director FC-64 units may receive one
of the following messages when they upgrade to firmware 05.02.00-13:
■HAFM—Firmware cannot be loaded due to insufficient
CTP memory.
■EWS—File System Error: Insufficient memory for new
firmware version.
This occurs only in certain units with CTP cards. Units with CTP2 cards do not
have this issue.
If you get one of these messages during the upgrade, the firmware upgrade failed,
but the unit continues working with the existing firmware without an interruption
in service. The upgrade process checks for sufficient memory before activating the
new firmware image. The firmware upgrade does not complete without sufficient
memory. Please contact HP Customer Support if you receive this message.
Upgrading firmware on an edge switch from 04.xx.xx to 05.xx.xx
An issue has been identified in release 04.xx.xx if the contents of the nonvolatile
storage (NVRAM) on the CTP become corrupted. Once the configuration has
been loaded, this corruption is not detected until an IPL/IML, power cycle, or
firmware code load. If the NVRAM in the CTP has corrupted contents, the
firmware load can cause the configuration to reset to factory defaults, which could
cause a system outage.
