Versionstring2.7.0 CIM_ProtectedExtentBasedOn
DescriptionstringProtected StorageExtents map to an underlying StorageExtent. This mapping includes information about the placement of check data on the underlying extent. The mapping is made explicit in this association. CIM_ProtectedExtentBasedOn
Associationbooleantrue CIM_ProtectedExtentBasedOn
DescriptionstringBasedOn is an association describing how StorageExtents can be assembled from lower level Extents. For example, ProtectedSpaceExtents are parts of PhysicalExtents, while VolumeSets are assembled from one or more Physical or ProtectedSpaceExtents. As another example, CacheMemory can be defined independently and realized in a PhysicalElement or can be ’ based on ’ Volatile or NonVolatileStorageExtents. CIM_BasedOn
Associationbooleantrue CIM_BasedOn
Associationbooleantrue CIM_Dependency
DescriptionstringCIM_Dependency is a generic association used to establish dependency relationships between ManagedElements. CIM_Dependency

Keybooleantrue CIM_BasedOn

Property Dependent Qualifiers
NameTypeValueFrom Class

DescriptionstringThe higher level StorageExtent. CIM_BasedOn
Keybooleantrue CIM_BasedOn

Property StartingAddress Qualifiers
NameTypeValueFrom Class
DescriptionstringStartingAddress indicates where in lower level storage, the higher level Extent begins. CIM_BasedOn

Property EndingAddress Qualifiers
NameTypeValueFrom Class
DescriptionstringEndingAddress indicates where in lower level storage, the higher level Extent ends. This property is useful when mapping non-contiguous Extents into a higher level grouping. CIM_BasedOn

Property OrderIndex Qualifiers
NameTypeValueFrom Class
DescriptionstringIf there is an order to the BasedOn associations that describe how a higher level StorageExtent is assembled, the OrderIndex property indicates this. When an order exists, the instances of BasedOn with the same Dependent value (i.e., the same higher level Extent) should place unique values in the OrderIndex property. The lowest value implies the first member of the collection of lower level Extents, and increasing values imply successive members of the collection. If there is no ordered relationship, a value of zero should be specified. An example of the use of this property is to define a RAID-0 striped array of 3 disks. The resultant RAID array is a StorageExtent that is dependent on (BasedOn) the StorageExtents that describe each of the 3 disks. The OrderIndex of each BasedOn association from the disk Extents to the RAID array could be specified as 1, 2 and 3 to indicate the order in which the disk Extents are used to access the RAID data.
