If you have purchased a disk enclosure optionally, use SAS cables to connect the disk array unit and
the disk enclosure.

For FC Port Connection
Use FC cables, to connect an application server and host connection ports on the disk array unit.
The figure below shows an example of recommended connection, which is a redundant-paths
configuration that works together with NEC Storage PathManager.
To implement this recommended connection, two host bus adapters need to be installed on the
application server.
Two FC cables are also required for connecting the disk array unit and the host bus adapters.
The dustproof covers on the host port on the controllers will be required for system
relocation, etc. in the future. Do not dispose of the covers after removing them from the
controllers.
Following is the procedure for connecting the disk array unit and the application server by using FC
cables:
Release 6.0
To prevent a wrong cable from being connected during cable replacement at the
system start or after a failure, attach the cable labels that come with units on to the
cables.
