Class Declaration Attributes Name Value SUPERCLASS CIM_BasedOn NAME CIM_CompositeExtentBasedOn
Class CIM_CompositeExtentBasedOn Qualifiers Name Type Value From Class Version string 2.7.0 CIM_CompositeExtentBasedOn Description string This specialization defines how data is striped across StorageExtents. Additionally, it includes information on distribution of check data so that the ’ usual case ’ RAID devices can be created in one step. CIM_CompositeExtentBasedOn Association boolean true CIM_CompositeExtentBasedOn Description string 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. CIM_BasedOn Association boolean true CIM_BasedOn Association boolean true CIM_Dependency Description string CIM_Dependency is a generic association used to establish dependency relationships between ManagedElements. CIM_Dependency
Property Qualifiers
Property Antecedent Qualifiers Name Type Value From Class Min uint32 1 CIM_CompositeExtentBasedOn Description string The underlying StorageExtent. CIM_CompositeExtentBasedOn Override string Antecedent CIM_CompositeExtentBasedOn Key boolean true CIM_CompositeExtentBasedOn
Property Dependent Qualifiers Name Type Value From Class Description string The CompositeExtent which is built on the StorageExtent. CIM_CompositeExtentBasedOn Override string Dependent CIM_CompositeExtentBasedOn Key boolean true CIM_CompositeExtentBasedOn
Property OrderIndex Qualifiers Name Type Value From Class Required boolean true CIM_CompositeExtentBasedOn Override string OrderIndex CIM_CompositeExtentBasedOn Description string Order matters to CompositeExtents. 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 CompositeExtent 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. CIM_CompositeExtentBasedOn MappingStrings string MIF.DMTF|Protected Space Extent|001.1 CIM_CompositeExtentBasedOn
Property LBAsMappedByDecrementing Qualifiers Name Type Value From Class Description string True if logical blocks in the underlying StorageExtents are mapped in decrementing order. This property corresponds to the INCDEC value in the SCC-2 Volume Set PS_Extent Descriptor. CIM_CompositeExtentBasedOn
Property LBAMappingIncludesCheckData Qualifiers Name Type Value From Class Description string 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. CIM_CompositeExtentBasedOn
Property NumberOfBlocks Qualifiers Name Type Value From Class Description string 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 SCC, this is equivalent to the NUMBER OF LBA_PS(s) field in the Volume Set PS_Extent Descriptor. CIM_CompositeExtentBasedOn MappingStrings string MIF.DMTF|Protected Space Extent|001.3 CIM_CompositeExtentBasedOn ModelCorrespondence string CIM_StorageExtent.NumberOfBlocks CIM_CompositeExtentBasedOn
Property BlockSize Qualifiers Name Type Value From Class Description string The Dependent ’ s BlockSize is limited by the Antecedent ’ s. In SCC, this is equivalent to the NUMBER OF BYTES PER LBA_PS field in the RedundancyGroup P_Extent Descriptor. CIM_CompositeExtentBasedOn Units string Bytes CIM_CompositeExtentBasedOn MappingStrings string MIF.DMTF|Protected Space Extent|001.4 CIM_CompositeExtentBasedOn ModelCorrespondence string CIM_StorageExtent.BlockSize CIM_CompositeExtentBasedOn
Property UserDataStripeDepth Qualifiers Name Type Value From Class Description string Number of bytes which form the stripe size for the Dependent StorageExtent. If the CompositeExtent is concatenated instead of striped, then UserDataStripeDepth should be set to zero. CIM_CompositeExtentBasedOn Units string Bytes CIM_CompositeExtentBasedOn MappingStrings string MIF.DMTF|Protected Space Extent|001.6 CIM_CompositeExtentBasedOn
Property UnitsBeforeCheckDataInterleave Qualifiers Name Type Value From Class Description string Number of bytes of user data to skip before starting the check data interleave. CIM_CompositeExtentBasedOn Units string Bytes CIM_CompositeExtentBasedOn MappingStrings string MIF.DMTF|Physical Extent|001.6 CIM_CompositeExtentBasedOn
Property UnitsOfCheckData Qualifiers Name Type Value From Class Description string Number of bytes to be reserved for check data. CIM_CompositeExtentBasedOn Units string Bytes CIM_CompositeExtentBasedOn MappingStrings string MIF.DMTF|Physical Extent|001.7 CIM_CompositeExtentBasedOn
Property UnitsOfUserData Qualifiers Name Type Value From Class Description string Number of bytes to be reserved for user data. CIM_CompositeExtentBasedOn Units string Bytes CIM_CompositeExtentBasedOn MappingStrings string MIF.DMTF|Physical Extent|001.8 CIM_CompositeExtentBasedOn
Property Antecedent Qualifiers Name Type Value From Class Override string Antecedent CIM_BasedOn Description string The lower level StorageExtent. CIM_BasedOn Key boolean true CIM_BasedOn
Property Dependent Qualifiers Name Type Value From Class Override string Dependent CIM_BasedOn Description string The higher level StorageExtent. CIM_BasedOn Key boolean true CIM_BasedOn
Property StartingAddress Qualifiers Name Type Value From Class Description string StartingAddress indicates where in lower level storage, the higher level Extent begins. CIM_BasedOn
Property EndingAddress Qualifiers Name Type Value From Class 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. CIM_BasedOn
Property OrderIndex Qualifiers Name Type Value From Class 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. CIM_BasedOn
Property Antecedent Qualifiers Name Type Value From Class Key boolean true CIM_Dependency Description string Antecedent represents the independent object in this association. CIM_Dependency
Property Dependent Qualifiers Name Type Value From Class Key boolean true CIM_Dependency Description string Dependent represents the object that is dependent on the Antecedent. CIM_Dependency
