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.

Optical link module.
OS
Operating system.
PA
Physical address.
parity group
A parity group is a disk con
fi
guration in which multiple disks
work together to provide redundancy. Synonymous with “array
group.”
partition
Dividing a speci

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.
