replica A point-in-time representation of a PS Series volume. The original volume and its replica are located on different PS Series groups (replication partners) potentially separated by some geographical distance to facilitate disaster tolerance. replica collection (Group Manager) The set of replicas resulting from each replication of a volume collection. replica collection set (Group Manager) The set of replica collections for a volume collection. replica container (NAS) (Group Manager) For NAS replication, a NAS container on a NAS cluster that stores inbound data copied from a source container on a replication partner. See NAS cluster, recovery container (NAS), and source container (NAS). replication (Group Manager) The process of copying volume data from one group to another, which protects the data from a variety of failures with no effect on data availability or performance. See the Dell EqualLogic Group Manager Administrator's Guide for more information. replication partner (Group Manager) A group that is configured to send or receive replicas from another partner. replica reserve (Group Manager) The portion of 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 (Group Manager) The set of complete replicas for a volume, template volume, or thin clone volume. S SAN Headquarters An application that enables you to monitor multiple PS Series groups from a single graphical interface. It (SAN HQ) gathers and formats performance data and other important group information. secondary group (Group Manager) In a replication configuration, the group that receives replicas of a source volume. See primary group. self-encrypting drive A self-encrypting drive (SED) performs Advanced Encryption Standard (AES) encryption on all data stored (SED) within that drive. To protect your company's valuable data, a SED will immediately lock itself when it is removed from the array or is otherwise powered down. If the drive is lost or stolen, its contents are inaccessible without the encryption key. service tag (Group Manager) A unique ID assigned by Dell to particular equipment, for use by customer service. shrink (volume) (Group Manager) Decreasing the reported size of a volume. single sign-on (SSO) (Group Manager) A feature that enables a user who has already logged in to a PC using Windows Active Directory (AD) credentials to log in to the Group Manager GUI without having to specify the credentials a second time. Smart Copy (Auto-Snapshot Manager/Microsoft Edition) A point-in-time, application-consistent copy of objects in a PS Series group. Smart Copies can be of type snapshot, clone, or replica, depending on the edition of AutoSnapshot Manager that you are using. smart tags Provide a mechanism for PS group administrators to organize, search, and filter the volumes in their groups. snapshot A point-in-time representation of a PS Series iSCSI volume or NAS container. Seen on the network as an iSCSI target, a snapshot is maintained in an array as deltas from the original volume. snapshot collection A set of snapshots resulting from a snapshot operation on a volume collection. See volume collection. source container (NAS) (Group Manager) For NAS replication, the NAS container from which data is copied to a replica container in the partner PS Series group. space borrowing (Group Manager) Includes snapshot space borrowing and replication borrowing. As of PS Series firmware v8.0, the following borrowing capabilities are available: Glossary Definitions 9
