Figure 7 – HP Smart Array profile: Extent Mapping Class Diagram
The Extent Mapping profile (Defined in SNIA SMI-S version 1.0.2) is used to model the relationship
between Storage Volumes and the actual disk drives (storage extents) that are used in the make up of
the volume. The implementation is restricted to primordial storage extents. These extents are associated
one to one with disk drive instances using the CIM_MediaPresent association.
