Cabling for 2- and 4-Port Fibre Channel Adapters
Workstations may be equipped with either or both 2-port and 4-port fibre channel adapters, depending on
the storage configurations available for that workstation. If the diagram for your workstation does not reflect
your fibre channel adapter configuration, use the following to determine which ports to connect to storage:
■ If the diagram illustrates a 4-port adapter and yours is a 2-port adapter, the illustration should show
connections for only the two innermost ports of the four ports. Ignore the two outermost ports and cable
according to the two innermost ports.
■ If the diagram illustrates a 2-port adapter, and yours is a 4-port adapter, connect the two innermost ports
to Stone Direct storage as indicated in the following diagram. Note that with a 4-port adapter you can
connect the two outermost ports to archiving devices, or to a Storage Area Network (SAN) system.
Depending on your configuration, it may also be possible to connect all four ports to a SAN.

Terminating 4-Port Fibre Channel Adapters
If you are not using the two outermost ports of a 4-port fibre channel adapter, it is recommended that you
terminate these ports using the FC loopback couplers that shipped with your system. Terminating these
ports significantly decreases the time required to boot the system.
HP z800
The following diagram illustrates 2-loop and optional 4-loop connections for the HP z800 workstation. The
same diagram can be used for the Lustre Media Server.
NOTE Terminate unused ports on a 4-port adapter using FC loopback couplers.
