Reference Guide
NAS controller (Group Manager) One of two redundant, hot-swappable controllers in a NAS appliance. Together, the
controllers are sometimes referred to as a NAS controller pair.
NAS data reduction (Network-attached storage) Process that analyzes les to determine if multiple copies of an individual le or
portions of a le, or blocks, can be saved in a more ecient format.
NAS data
rehydration
(Network-attached storage) Restores data that was reduced during the data reduction process.
NAS reserve (Network-attached storage) Storage pool space allocated to a NAS cluster for storing internal data and user
data and congured with DSFS.
P
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 congured 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
specic 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 specic
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 congured for replication to a replication partner.
PS series array A single EqualLogic iSCSI storage unit, usually congured 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 recoverable volume.
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 NAS cluster, replica container (NAS), and source container (NAS).
recovery volume Temporary volume created by promoting an inbound replica set as part of a failover operation. You can also
create recovery template volumes and recovery thin clones.

Remote Setup
Wizard Command
Line Interface
(RSWCLI)
(Host Integration Tools) Interfaces that enable you to congure a PS Series array after you install the Host
Integration Tools.
