10 Configuring Enterprise-class platforms Ports Because enterprise-class platforms contain interchangeable port blades, their procedures differ from those for fixed-port switches. For example, fixed-port models identify ports only by the port number, while enterprise-class platforms identify ports by slot/port notation. NOTE: For detailed information about the HP StorageWorks 4/256 SAN Director, the HP StorageWorks DC SAN Backbone Director, and HP StorageWorks DC04 SAN Director Switch enterprise-class platforms, see the relevant hardware documentation. The different blades that can be inserted into a chassis are described as follows: • Control processor blades (CPs) contain communication ports for system management, and are used for low-level, platform-wide tasks. In the HP StorageWorks 4/256 SAN Director, CPs are used for intra-platform switching. • Core blades in the HP StorageWorks DC SAN Backbone Director (CORE8) and HP StorageWorks DC04 SAN Director Switch (CR4S-8) are used for intra-chassis switching as well as interconnecting two HP StorageWorks DC SAN Backbone Director enterprise-class platforms. • 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, storage virtualization, and encryption support. The HP StorageWorks 4/256 SAN Director has 10 slots that contain control processor, port, and application (AP) blades: • Slot numbers 5 and 6 contain control processor blades. • Slot numbers 1 through 4 and 7 through 10 contain port and AP blades. The HP StorageWorks DCX SAN Backbone Director has 12 slots that contain control processor, core, port, and AP blades: • Slot numbers 6 and 7 contain CPs. • Slot numbers 5 and 8 contain core blades. • Slot numbers 1 through 4 and 9 through 12 contain port and AP blades. The HP StorageWorks DC04 SAN Director Switch has 8 slots that contain control processor, core, port, and AP blades: • Slot numbers 4 and 5 contain CPs. • Slot numbers 3 and 6 contain core blades. • Slot numbers 1 and 2, and 7 and 8 contain port and AP blades. On each port blade, a particular port must be represented by both slot number and port number. NOTE: The Core blades for the HP StorageWorks DC SAN Backbone Director (CORE8) and the HP StorageWorks DC04 SAN Director Switch (CR4S-8) are not interchangeable between the two products. 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 (Multi-Protocol Router blade), or 16-port and 48-port blades), the area IDs no longer match the port numbers. Table 67 lists the port numbering schemes for the HP StorageWorks 4/256 SAN Director, HP StorageWorks DC SAN Backbone Director and HP StorageWorks DC04 SAN Director Switch enterprise-class platforms.
