Class CIM_PhysicalExtent
extends CIM_StorageExtent

A PhysicalExtent is used to model an SCC RAID implementation. It defines the consecutive addressable block addresses on a single storage device, that are treated as a single StorageExtent and that are in the same StorageRedundancyGroup. An alternate possibility, if automatic configuration is used, is to instantiate or extend the AggregatePExtent class.
