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
directors in a single fabric is 31. The supported limit of interconnected switches
inasinglefabricis24.Becausethisnumberissubjecttochange,contactyour
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.
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 theEdgeSwitch2/12,EdgeSwitch2/12,andEdgeSwitch2/32
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.
Minor Code Enhancements and Fixes in fw 07.01.02-4
This release of firmware version 07.01.02-4 incorporates some minor code enhancements
and fixes, and is not a mandatory upgrade, though HP recommends that all directors
and edge switches be upgraded to this version of firmware. Firmware release 07.01.02-4
is based on firmware 07.00.00-84, and contains all fixes included in that version and
prior releases. The following are now incorporated in firmware version 07.01.02-4.
Directors take new action upon detecting a failed UPM port module
A particular type of failure in director UPM port modules could be disruptive to other
port modules in a director. In the release of firmware 07.01.02-4, the action taken by
the director upon detecting this type of failure was changed to power off the failed port
module to prevent it from affecting other working port modules.
Embedded Web Server zoneset activation timeout issue resolved
Under certain conditions, the Embedded Web Server (EWS) would sometimes not allow
theZoneManagersubsystemenoughtimetoprocessaconfiguration change request.
This would cause EWS to time out when waiting for the Zone Manager to respond.
When this occurred, the Zone Manager could hang indefinitely, preventing any further
zone activities from any management location. This timeout issue has been fixed.
Edge Switch release notes 5

Zonesets containing domain/port number zones while in Open Fabric interop mode no longer
cause zoning to hang
When directors and edge switches in a fabric were configured for Open Fabric 1.0
interop mode, and the fabric’s zoneset contained a zone with members defined by
domain/port number instead of World Wide Name, activating changes to the zoneset
could cause the Zone Manager to hang. When this occurred, the Zone Manager could
hang indefinitely, preventing any further zone activities from any management location.
It should be noted that domain/port number zones are not supported in Open Fabric
1.0 interop mode, and are ignored. The Zone Manager will no longer hang under these
conditions, and these zones are still ignored in Open Fabric 1.0 interop mode.
Occasional Ethernet hang issue is resolved
Under certain conditions, the Ethernet communications could intermittently hang on
director 2/140, edge switch 2/24, and edge switch 2/12. This issue has been
corrected.
Features not supported in this release
The following director and edge switch feature is not supported in this release:
•SANtegrity Authentication
The following HAFM features are not supported in this release:
•SANtegrity Security Center
•Group Configuration Manager
These features are described in the documentation released with firmware 07.00.00 and
HAFM 08.06.00. Some of these features may be available in a future release.
Documentation released with firmware 07.00.00 and HAFM 08.06.00
To support these products, we are providing documentation from both McDATA
Corporation (the product developer) and from HP (the product OEM). The HP documents
include all information HP has incorporated into the products to date. The McDATA
documents include only the basic product information.
