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

• 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 a ll 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 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 shor t-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 opp osite end of the cable must be of either LC or SC type, depending on the requirements of the connected device.

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 ﬁ rmware. 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 cer tain 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

Zonesets containing domain/port number zones while in Open Fabric interop mode no longer cause zoning to han

When directors an interop mo d e, and 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 cou ld hang indeﬁnitely, preventing any further zone activities from any management location. It should be noted that domain/port number zones are not suppor ted in Open Fabric

1.0 interop mo 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.
