|
Description
|
StartingAddress indicates where in lower level storage, the higher level Extent begins. |
|
| EndingAddress |
uint64 |
CIM_BasedOn |
|
Description
|
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 |
|
Description
|
Order matters to composite extents. An example of the use of this property is when defining a RAID-0 striped array of 3 disks. The resultant RAID array is a composite extent that is dependent on (as described by CompositeExtentBasedOn) the StorageExtents that represent each of the 3 disks. The OrderIndex of each CompositeExtentBasedOn 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. |

| LBAsMappedByDecrementing |
boolean |
CIM_CompositeExtentBasedOn |
|
Description
|
True if logical blocks in the underlying StorageExtents are mapped in decrementing order. This property corresponds to the INCDEC value in the SCSI SCC-2 Volume Set PS_Extent Descriptor. |
|
| LBAMappingIncludesCheckData |
boolean |
CIM_CompositeExtentBasedOn |
|
Description
|
True if the logical block mapping algorithm includes check data bytes. This property corresponds to the NOCHKSKIP attribute in the SCC-2 Volume Set PS_Extent Descriptor. |
|
| NumberOfBlocks |
uint64 |
CIM_CompositeExtentBasedOn |
|
Description
|
The total number of blocks that will be consumed on the Dependent Extent. This is limited by the Antecedent's NumberOfBlocks, but is included explicitly to provide for the DMTF MIF mapping. In SCSI SCC, this is equivalent to the NUMBER OF LBA_PS(s) field in the Volume Set PS_Extent Descriptor. |

Description
|
The Dependent's BlockSize is limited by the Antecedent's. In SCSI SCC, this is equivalent to the NUMBER OF BYTES PER LBA_PS field in the RedundancyGroup P_Extent Descriptor. |
