peer node
(Network-attached storage) NAS node with which a NAS node is paired in a NAS cluster.
peer storage group
(PSG)
One or more EqualLogic peer storage
arrays
that are
configured
to act as a single SAN storage device.
pool
Storage space provided by one to eight members (and up to four pools in a group). You assign volumes to a
specific
pool, and load balancing operates only within pools.
pool administrator
(Group Manager) An account on a PS Series group that has permission to manage objects only in a
specific
pool or set of pools for a group. Compare to
group administrator
.
primary group
(Group Manager) In a replication partnership, the group containing the original volume. See
secondary
group
.
primary volume
(Group Manager) A volume
configured
for replication to a replication partner.
PS series array
A single EqualLogic iSCSI storage unit, usually
configured
as a PS Series group. You can join multiple PS
Series arrays into a larger PS Series group and manage them as a single iSCSI SAN.
PS Series group
An iSCSI storage entity comprising one or more PS Series storage arrays that you access through a single IP
address and manage as a storage area network (SAN).
R
recoverable volume
(Group Manager) Deleted volumes are placed in the recovery bin, where they remain until they are purged or
recovered. Recovering a volume moves the volume from the recovery bin back to the group. Volumes with
no data are automatically deleted. Volumes in the recovery bin can be purged by the system if free space is
needed for any other purpose.
recovery bin
(Group Manager) Area of pool free space used to preserve recoverable volumes. Volumes in the recovery
bin can be restored or purged. See

recovery container
(NAS)
(Group Manager) For NAS replication, a destination container that is temporarily promoted for the purpose
of recovering data from the replica. See
