The number of supported ports on an XP disk array is dependent upon the number of
supported I/O slots and the number of ports available per I/O adapter. The XP family of
disk arrays supports SCSI, Fibre Channel (FC/AL), and ESCON I/O interfaces. I/O
support may vary with the selected disk array.
A port is named based upon its port group and port letter. Examples of port names
include CL1-A through CL1-R and CL2-A through CL2-R (letters I and O are
skipped).
Point-to-point.
Peer-to-peer remote copy.
