# Class CIM_DiskGroup
extends CIM_CollectionOfMSEs

A DiskGroup is a named collection of DiskDrives and the StorageExtents accessed using those Drives. The collection is used to limit the BasedOn relationships of the Extents in the DiskGroup. Extents in the Group cannot be BasedOn storage accessed from Drives outside of the Group. For example, a SoftwareVolume created within the DiskGroup is restricted to be completely accessed using Drives in the Group. Actions such as replicate or migrate on an Extent must operate within the scope of the Extents that are present in the DiskGroup.
