MIX
A circuit board in the disk control unit that includes disk
adapters and channel adapters for interfacing disk drives and
the host to cache memory.
mirroring consis-
tency
The consistency (usability) of data in a volume (for example,
S-VOL).
mm
Millimeters.
MR
Magnetoresistive.
ms, msec
Milliseconds.
mutual hot
standby system
Two servers that are poised to cover for each other if necessary.
NAS
Network attached storage.

Logically speaking, an environment where instances can be
executed. Physically, a processor, which is an element of a
cluster system.
NVS
Nonvolatile storage.

parity group
A parity group is a disk con

there are two or more physical disks.
path
Paths are created by associating a port, a target, and a LUN
ID with one or more LDEVs.
PCI
Power control interface or peripheral component interconnect.
port
A physical connection that allows data to pass between a
host and the disk array. The number of ports on an XP disk
array depends on the number of supported I/O slots and the
number of ports available per I/O adapter. The XP family of
disk arrays supports Fibre Channel (FC) ports as well as other
