Subclass of CIM_Dependency
Abstract BasedOn is an association describing how StorageExtents (or views of StorageExtents) can be assembled from lower level Extents (or views of extents).
CIM_ManagedElement Dependent
The higher level StorageExtent (or view of the extent).
CIM_ManagedElement Antecedent
The lower level StorageExtent (or view of the extent).
uint64 StartingAddress
StartingAddress indicates where in lower level storage, the higher level Extent begins.
uint64 EndingAddress
EndingAddress 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.
uint16 OrderIndex
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.
