9 Configuring Directors This chapter contains procedures that are specific to the SAN Director 128 and 4/256 SAN Director models. Because Directors contain interchangeable port blades, install procedures differ from the SAN Switches, which operate as fixed-port switches. For example, fixed-port models identify ports by domain, port number, while Director models identify ports by slot/port number. The two available Director models (namely the SAN Director 2/128 and 4/256 SAN Director) in their default configurations have only one domain (the 4/256 SAN Director supports one domain only). For more detailed information about the SAN Director 128 and 4/256 SAN Director models, see the SAN Director installation guide. Identifying ports The SAN Director 2/128 and 4/256 SAN Director models have slots and can have a variable number of ports within a given domain. Ports are identified by their combined slot number and port number. There are 10 slots that contain port blades: • Slot numbers 5 and 6 contain control processor blades (CPs). • Slot numbers 1 through 4 and 7 through 10 contain port blades. NOTE: CPs perform blade-to-blade switching over the Director's passive backplane, contain communication ports for system management, and are used for low-level, chassis-wide tasks. Port blades are used for host, storage, and interswitch connections. On each port blade, there are 16 FC, 16 (8 FC and 8 iSCSI), 18 (16 FC ports and 2 GbE ports), 32, or 48 ports (counted from the bottom, 0 to 15, 0 to 31, or 0 to 23 and 24 to 47). A particular port must be represented by both slot number (1 through 4 and 7 through 10) and port number (0 through 15). When you have port blades with different port counts in the same Director (for example, 16-port blade and 32-port blades, or 16-port blades and 18-port blades with 16 FC ports and 2 GbE ports, or 16-port and 48-port blades), the area IDs no longer match the port numbers. Following are the port numbering schemes for the 4/256 SAN Director: IMPORTANT: At the time of this document's release, HP does not support the FC4-16IP blade. Consult http://www.hp.com for the latest, updated information. • For the FC4-16 port blade, ports are numbered from 0 through 15 from bottom to top. • For the FC4-32 port blade, ports are numbered from 0 through 15 from bottom to top on the left set of ports and 16 through 31 from bottom to top on the right set of ports. • 4/256 SAN Director only: For the B-Series MP Router port blade (FR4-18i), ports are numbered from 0 through 15 from bottom to top. There are also 8 GbE ports (numbered ge0 - ge7). So going from bottom to top, the 8 FC ports appear on the bottom, followed by the GbE ports at the top. • 4/256 SAN Director only: For the FC4-16IP port blade, Fibre Channel ports are numbered from 0 through 7 from bottom to top. There are also 2 GbE ports (numbered ge0 - ge1). So going from bottom to top, the 2 physical GbE ports appear on the bottom of the blade followed by 16 physical FC ports. • 4/256 SAN Director only: For the FC4-48 port blade, ports are numbered from 0 through 23 from bottom to top on the left set of ports and 24 through 47 from bottom to top on the right set of ports. In the 4/256 SAN Director, all the ports are part of a single logical switch. With Fabric OS v4.4.0 and later, you can configure the SAN Director 2/128 as two logical switches (domains).
