# Class CIM_ProtectedSpaceExtent
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 ProtectedSpaceExtent is used to model an SCC RAID implementation. ProtectedSpaceExtent defines addressable logical block addresses, treated as a single Extent, located on one or more PhysicalExtents. ProtectedSpaceExtents exclude any logical blocks mapped as check data and contain user data stripe depth mapping information. An alternate possibility, if automatic configuration is used, is to instantiate or extend the AggregatePSExtent 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.

Deprecated | string | CIM_CompositeExtentBasedOn.NumberOfBlocks, CIM_ProtectedExtentBasedOn.NumberOfBlocks
Description | string | The number of user data blocks contained in this Extent.

UserDataStripeDepth | uint64 |
Deprecated | string | CIM_CompositeExtentBasedOn.UserDataStripeDepth
Description | string | For a ProtectedSpaceExtent that is allocated to a Volume Set (i.e. is named in a CIM_VolumeSetBasedOnPSExtent association), this property is the number of user data bytes placed on this ProtectedSpaceExtent before moving on to the next ProtectedSpaceExtent in the VolumeSet. Otherwise, this ProtectedSpaceExtent is considered to be unallocated, and this property shall be set to zero (0h.)
