Class CIM_PhysicalExtent
extends CIM_StorageExtent

Deprecated - use CIM_ProtectedExtentBasedOn or CIM_CompositeExtentBasedOn instead. The information on check and user data is better expressed in the association that layers the storage, than in the extent itself. 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.

BlockSize	uint64
			Deprecated	string	CIM_CompositeExtentBasedOn.BlockSize, CIM_ProtectedExtentBasedOn.BlockSize
			Description	string	Size in bytes of the blocks which form this StorageExtent. If variable block size, then the maximum block size in bytes should be specified. If the block size is unknown or if a block concept is not valid (for example, for AggregateExtents, Memory or LogicalDisks), enter a 1.

NumberOfBlocks	uint64
			Deprecated	string	CIM_CompositeExtentBasedOn.NumberOfBlocks, CIM_ProtectedExtentBasedOn.NumberOfBlocks
			Description	string	Total number of logically contiguous blocks, of size Block Size, which form this Extent. The total size of the Extent can be calculated by multiplying BlockSize by NumberOfBlocks. If the BlockSize is 1, this property is the total size of the Extent.
