failure. Single Redundancy protects against loss of data if any one resource fails. Dual
Redundancy protects against data lost if any two resources fail.
Redundant Array of
Independent Disks
(RAID) Redundant array of independent disks. A method of providing data redundancy. Some
common implementations of RAID including RAID 0, RAID 1, RAID 5, RAID 10, and RAID 50.
See mirroring, striping.
Remote Instant Replay A Dell Compellent Storage Center solution feature in which a replay is replicated to a remote
Dell Compellent Storage Center. The local and remote Dell Compellent Storage Centers are
active-active, and bidirectional replication can occur, synchronously or asynchronously, on
independent intervals. Dell Compellent Storage Center replication requires the Enterprise
Manager software application with a Replication license. See Replay, Remote System,
replication.
Remote Setup Wizard
(RSW) A graphical user interface (GUI) that enables you to configure a Dell EqualLogic PS Series
array after you install the Host Integration Tools/Microsoft Edition.
Remote System In Dell Compellent Storage Center, a separate SAN configured to receive replication data
from an original volume on the local Dell Compellent Storage Center. Dell Compellent
Storage Center replication requires the Enterprise Manager software application with a
Replication license. See replication.
Replay In Dell Compellent Storage Center, a fully usable, point-in-time copy (PITC) of data that
contains an image of the data as it appeared at the point in time at which the copy was
initiated. The copy may be stored locally or on a remote Dell Compellent Storage Center.
See snapshot, Data Instant Replay, Remote Instant Replay.
Replay Profile In Dell Compellent Storage Center, a set of rules that determine when and how replays point-
in-time copies will be taken and how long they will be saved. See Replay.
Replay space In Dell Compellent Storage Center, the amount of space that is automatically reserved and
used for replays. See active space, actual space.
replica A point-in-time representation of a Dell EqualLogic PS Series volume. The original volume
and its replica are located on different Dell EqualLogic PS Series groups (replication
partners) potentially separated at some geographical distance to facilitate disaster
tolerance.
replica collection In Dell EqualLogic Group Manager, the set of replicas resulting from each replication of a
volume collection.
replica collection set In Dell EqualLogic Group Manager, the set of replica collections for a volume collection.
replica reserve In Dell EqualLogic Group Manager, the portion of the delegated space on a replication
partner that is set aside for the replica sets for a specific volume. You configure the replica
reserve for the volume on the primary group, but the actual replica reserve is on the
secondary group.
replica set In Dell EqualLogic Group Manager, the set of complete replicas for a volume, template
volume, or thin clone volume.
replicating system A Dell Compellent Storage Center configured to send replication data from one or more local
volumes to a remote Storage Center. See replication, Remote System, Remote Instant
Replay.
