port A physical connection that allows data to pass between a host and the disk array. The number
of ports on a disk array depends on the number of supported I/O slots and the number of ports
available per I/O adapter. The P9000 and XP family of disk arrays supports Fibre Channel (FC)
ports as well as other port types. Ports are named by port group and port letter, such as CL1-A.
CL1 is the group, and A is the port letter.

PSUS Pair suspended-split.
R-VOL Remote volume.

Group.
