# Class CIM_AggregatePExtent
extends CIM_StorageExtent

This class is deprecated in lieu of the generic StorageExtent object and the ProtectedExtentBasedOn association. An AggregatePExtent is used to model an SCC RAID implementation. AggregatePExtents provide summary information about the addressable logical blocks which are in the same StorageRedundancyGroup and reside on the same storage device. This is an alternative grouping for PhysicalExtents, when only summary information is needed or when automatic configuration is used.

### Local Class Properties

Name | Data Type | Default Value | Qualifiers
--- | --- | --- | ---
Name | Data Type | Value
BlocksOfCheckData | uint64 |
Deprecated | string | CIM_CompositeExtentBasedOn.UnitsOfCheckData
Description | string | The number of blocks contained in this AggregatePExtent to be used as check data. If this AggregatePExtent is available, then this value shall be zero.
MappingStrings | string | MIF.DMTF|Aggregate Physical Extent|001.3
NumberOfBlocks | uint64 |
Deprecated | string | CIM_CompositeExtentBasedOn.NumberOfBlocks, CIM_StorageExtent.NumberOfBlocks
Description | string | Total number of blocks (including the check data blocks) contained in this AggregatePExtent. The block size (an inherited property) should be set to the same value as for the MediaAccessDevice associated with this Extent.
