A storage group is a collection of storage units that jointly contain all the data for a specified set of storage units, such as volumes. The storage units in a group must be from storage devices of the same type.
Groups can be created to identify sets of volumes that need to be managed as a consistent unit. A general purpose group can be used as a container for volumes that share some association, for example a group of volumes that are all associated with a specific application. A group can contain any set of compatible managed elements, for example managed disks (MDisks).
After a storage group is created, you can perform the following tasks:
A storage group can be managed by a Replication Manager session, so that copy tasks can be performed between storage groups.
