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 ).
