13 Glossary Glossary array Short for storage array. See storage array. container A container is virtual disk space that is preallocated for later use as a snapclone or a snapshot. For details, see containers topic. controller software (VCS / XCS) Controller software is low-level software (firmware) used by array controllers to run a storage array. In HP Replication Solutions Manager environments, the arrays may be running VCS or XCS versions that support different features. For details, see controller software features. DR group A data replication (DR) group is a logical group of virtual disks in a remote replication relationship with a corresponding group on another array. Hosts write data to the virtual disks in the source DR group, and the array copies the data to the virtual disks in the destination DR group. The virtual disks in a DR group fail over together, share a log, and preserve write order within the group. A pair of source and destination virtual disks is called a copy set. For details, see DR group pairs. dynamic capacity policy (DC-Management) Feature enabling you to extend or shrink the size of a host volume. See dynamic capacity management. EVA Enterprise Virtual Array. A family of HP StorageWorks enterprise class storage arrays. general purpose server A server whose purpose is to run a variety of applications, including HP StorageWorks applications. Compare with storage management server. host A computer that is connected to a storage array for the purpose of reading and writing data from the arrays' virtual disks. For details, see enabled and standard hosts. host volume Storage capacity that is defined and mountable by a host operating system.
