BlockSizeuint64
DescriptionstringThe block size of the protected space. Note that this is limited by the Antecedent->BlockSize. In SCC, this is equivalent to the NUMBER OF BYTES PER LBA_P field in the Redundancy Group P_Extent Descriptor.

NumberOfBlocksuint64
DescriptionstringThe size of the protected space. Note that this is limited by the Antecedent->NumberOfBlocks, but is included explicitly to provide for the DMTF MIF mapping. In SCC, this is equivalent to the NUMBER OF LBA_P(s) field in the Redundancy Group P_Extent Descriptor.
