Class CIM_BasedOn
extends CIM_Dependency

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.

Name	Data Type	Default Value	Qualifiers
Name	Data Type	Default Value	Name	Data Type	Value
EndingAddress	uint64
EndingAddress	uint64		Description	string	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.
OrderIndex	uint16
OrderIndex	uint16		Description	string	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	uint64		Description	string	StartingAddress indicates where in lower level storage, the higher level Extent begins.
