9 Configuring Directors This chapter contains procedures that are specific to the: • HP StorageWorks 4/256 SAN Director • HP StorageWorks DC SAN Backbone Director For detailed information see the HP StorageWorks SAN Director hardware reference manual or the HP StorageWorks DC SAN Backbone Director hardware reference manual. Identifying ports Because Directors contain interchangeable port blades, their procedures differ from those for fixed-port switches. For example, fixed-port models identify ports by domain, port number, while Director models identify ports by slot/port number. The HP StorageWorks 4/256 Director integrates 10 slots that contain control processor, port, and application (AP) blades: • Slot numbers 5 and 6 contain control processor blades (CPs). • Slot numbers 1 through 4 and 7 through 10 contain port and AP blades. The HP StorageWorks DC SAN Backbone Director (short name, DC Director) integrates 12 slots that contain control processor, core, port, and AP blades: • Slot numbers 6 and 7 contain control processor blades (CPs). • Slot numbers 5 and 8 contain core blades. • Slot numbers 1 through 4 and 9 through 12 contain port and AP blades. NOTE: CPs contain communication ports for system management, and are used for low-level, chassis-wide tasks. In the 4/256 Director, CPs are used for intra-chassis switching. Core blades are used for intra-chassis switching as well as interconnecting two DC Director chassis. Port blades are used for host, storage, and interswitch connections. AP blades are used for Fibre Channel Application Services and Routing Services, iSCSI bridging, FCIP, and storage virtualization. On each port blade, a particular port must be represented by both slot number and port number. When you have port blades with different port counts in the same Director (for example, 16-port blades 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.
