HP XP Array Manager Software - Manual (Page 68)

Port names can differ, depending on whether ports are in Standard mode, High Speed mode, or
Initiator/External MIX mode. For detailed information about port names, see tables later in this section.
Note:
• Sometimes the Standard mode, the High Speed mode, and the Initiator/External MIX mode are
collectively referred to as Fibre PCB modes. PCB is an acronym for printed circuit board. The
storage system documentation sometimes uses the term PCB when referring to a channel adapter,
which is a printed circuit board used for connecting hosts and a storage system.
• Storage partition administrators cannot apply the High Speed mode or the Initiator/External
MIX mode.
