9 Configuring Directors
This chapter contains procedures that are specific to the SAN Director 128 and 4/256 SAN Director
models. For detailed information about these models, r efer to the HP StorageWorks SAN Director
installation guide available on http://www.hp.com .
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 a particular port must be represented by both slot number (1 through 4 and 7 through
10) and port number.
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. Table 51 lists the port numbering schemes
for the 4/256 SAN Director:

FC2-16
FC4-16
Ports are numbered from 0 through 15 from bottom to top.
FC4-32 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.
FC4-48 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.
FC10-6 Ports are numbered from 0 through 5 from bottom to top.
FC4-16IP Fibre Channel ports are numbered from 0 through 7 from bottom to top. There
are also 8 GbE ports (numbered ge0 – ge7, from bottom to top). Going from
bottom to top, the 8 FC ports appear on the bottom, followed by the 8 GbE ports
at the top.
