| Name | Data Type | Qualifiers |
| Name | Data Type | Value | Scope | Flavors |
| Access | uint16 |
| Description | string | Access describes whether the media is readable (value=1), writeable (value=2), or both (value=3). "Unknown" (0) and "Write Once" (4) can also be defined. | None | TRANSLATABLE= true |
| Values | string | Unknown, Readable, Writeable, Read/Write Supported, Write Once | None | TRANSLATABLE= true |
| BlockSize | uint64 |
| Description | string | Size in bytes of the blocks which form this StorageExtent. If variable block size, then the maximum block size in bytes should be specified. If the block size is unknown or if a block concept is not valid (for example, for Aggregate Extents, Memory or LogicalDisks), enter a 1. | None | TRANSLATABLE= true |
| MappingStrings | string | MIF.DMTF|Host Storage|001.4, MIB.IETF|HOST-RESOURCES-MIB.hrStorageAllocationUnits, MIF.DMTF|Storage Devices|001.5 | None | None |
| Units | string | Bytes | None | TRANSLATABLE= true |
| ConsumableBlocks | uint64 |
| Description | string | The maximum number of blocks, of size BlockSize, which are available for consumption when layering StorageExtents using the BasedOn association. This property only has meaning when this StorageExtent is an Antecedent reference in a BasedOn relationship. For example, a StorageExtent could be composed of 120 blocks. However, the Extent itself may use 20 blocks for redundancy data. If another StorageExtent is BasedOn this Extent, only 100 blocks would be available to it. This information ('100 blocks is available for consumption') is indicated in the ConsumableBlocks property. | None | TRANSLATABLE= true |
| DataOrganization | uint16 |
| Description | string | Type of data organization used. | None | TRANSLATABLE= true |
| Values | string | Other, Unknown, Fixed Block, Variable Block, Count Key Data | None | TRANSLATABLE= true |
| ErrorMethodology | string |
| Description | string | ErrorMethodology is a free-form string describing the type of error detection and correction supported by this StorageExtent. | None | TRANSLATABLE= true |
| IsBasedOnUnderlyingRedundancy | boolean |
| Description | string | True indicates that the underlying StorageExtent(s) participate in a StorageRedundancyGroup. | None | TRANSLATABLE= true |
| NumberOfBlocks | uint64 |
| Description | string | Total number of logically contiguous blocks, of size BlockSize, which form this Extent. The total size of the Extent can be calculated by multiplying BlockSize by NumberOfBlocks. If the BlockSize is 1, this property is the total size of the Extent. | None | TRANSLATABLE= true |
| MappingStrings | string | MIF.DMTF|Host Storage|001.5, MIB.IETF|HOST-RESOURCES-MIB.hrStorageSize | None | None |
| Purpose | string |
| Description | string | A free form string describing the media and/or its use. | None | TRANSLATABLE= true |
| MappingStrings | string | MIB.IETF|HOST-RESOURCES-MIB.hrStorageDescr | None | None |
| SequentialAccess | boolean |
| Description | string | Boolean set to TRUE if the Storage is sequentially accessed by a MediaAccessDevice. A TapePartition is an example of a sequentially accessed StorageExtent. StorageVolumes, DiskPartitions and LogicalDisks represent randomly accessed Extents. | None | TRANSLATABLE= true |
