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
