Firmware 09.09.02
Firmware 09.09.02 is the latest firmware released for the HP M-series Edge Switches and Directors.
This firmware is common for all M-series fabric products, except the McDATA 4-Gb SAN Switch for
HP p-Class BladeSystem, which has separate firmware.
The firmware is available on the following HP website: http://h18006.www1.hp.com/storage/
networking/index.html. Select Retired Products and navigate to your switch model, and then to
Download drivers and software.
With the release of firmware 09.09.02, version 09.06.02 is now moved to INACTIVE status.
For more information on upgrading firmware versions, see the appropriate Director or Edge Switch
service manual.
Supported configurations
Operating multiple switches in a fabric topology is subject to topology limits. Consider the impact of
the following topology limits when planning the fabric:
• Fabric elements—Each fabric element is defined by a unique domain ID that ranges from 1 to 31;
therefore, the theoretical limit of interconnected Directors in a single fabric is 31. The supported
limit of interconnected switches in a single fabric is 24. The supported limit of interconnected
switches in a single fabric can be increased to 31, provided that any Edge Switch 2/16, Edge
Switch 2/32, or Director 2/64 in the fabric is deployed at the edge of the fabric. However, be-
cause this is subject to change, contact your HP-authorized service representative for the current
number of interconnected switches supported in a single fabric.
• Heterogeneous fabric—To determine if interoperability is supported for a product, or if restrictions
apply, see the product publications or contact your HP-authorized service representative.
• Number of interswitch links (ISLs)—The maximum number of ISLs supported is 75% of installed
ports for the Director 2/64, and 100% of installed ports for the Director 2/140. The maximum
number of ISLs supported for Edge Switches is all available switch ports. For redundancy, at least
two ISLs should connect any two Edge Switch or Director-class fabric elements. Because this inform-
ation is subject to change, contact your HP-authorized service representative for the current number
of ISLs supported for each Director or Edge Switch.
• Hop count—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. 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 information is subject to change,
contact your HP-authorized service representative for the current hop count supported by a single
fabric path.
