container
A container is virtual disk space that is preallocated for later use as a snapclone or a snapshot. For
details, see containers
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
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
dynamic capacity policy (DC-Management)
Feature enabling you to extend or shrink the size of a host volume. See
