Class CIM_BasedOn


CIM_Dependency


Description

BasedOn 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.

IdTypeRangeDescription
Key
Antecedent CIM_ManagedElement
Antecedent represents the independent object in this association.
Dependent CIM_ManagedElement
Dependent represents the object that is dependent on the Antecedent.
Read Only
EndingAddress uint64
EndingAddress indicates where in lower level storage, the higherlevel Extent ends. This property is useful when mapping non-contiguous Extents into a higher level grouping.
OrderIndex uint16
If 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.
StartingAddress uint64
StartingAddress indicates where in lower level storage, the higher level Extent begins.
