HP StorageWorks 2/12 HP StorageWorks Director and Edge Switch release notes (5 - Page 4

HP name N/A McDATA/Brocade name Sphereon 4700 Fabric Switch, Brocade M4700 Fabric Switch HAFM Basic (formerly, Embedded Web Server or EWS) EFCM Basic Edition (formerly, SANpilot) HA-Fabric Manager (HAFM) Enterprise Fabric Connectivity Manager (EFCM) Firmware Enterprise Operating System (E/OS) HAFM Appliance EFC Server Firmware 09.08.01 Firmware 09.08.01 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. 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, because this 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, 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 information 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. 4
