| ElementType | uint16 |
| Description | string | Defines the role that the element played for which this statistics record was collected. If the metered element is a system or a component of a system associated to a RegisteredProfile, then that profile may provide a more specialized definition and additional usage information for this property.
Generally, the ElementTypes defined here have the following meaning in the context of this class: 2, "Computer System": Cumulative statistics for the storage system. In the case of a complex system with multiple component Computer Systems, these are the statistics for the top-level aggregate Computer System. 3, "Front-end Computer System": Statistics for a component computer system that communicate with systems that initiate IO requests. 4, "Peer Computer System": Statistics for a component computer system that communicates with peer storage systems e.g. to provide remote mirroring of a volume. 5, "Back-end Computer System": Statistics for a component computer system that communicates with back-end storage. 6, "Front-end Port": Statistics for a port that communicates with systems that initiate IO requests. 7, "Back-end Port": Statistics for a port that initiates IO requests to storage devices. 8, "Volume": Statistics for an exposable storage extent, such as a StorageVolume or LogicalDisk. 9, "Extent": Statistics for an intermediate storage extent, i.e. an extent that is neither a volume or a disk. 10, "Disk Drive: Statistics for a StorageExtent that is associated to a DiskDrive through the MediaPresent association. 11, "Arbitrary LUs": Statistics that derive from access to Logical Units that are NOT StorageVolumes (e.g., controller commands). 12, "Remote Replica Group": Statistics for control IOs between an array and a remote mirror across a Network. Note that statistics for the actual movement of data to the remote mirror are attributed to the targeted StorageVolume (or LogicalDisk). Note that a particular element could be associated to multiple BlockStorageStatisticalData instances if it had multiple roles. For example, a storage array could contain redundant component computer systems that communicate both with hosts on the front end and disks on the back end. Such a device could have one BlockStorageStatisticalData instance where ElementType=3 and another instance where ElementType=5. | None | TRANSLATABLE= true |

| IdleTimeCounter | uint64 |
| Counter | boolean | true | None | None |
| Description | string | The cumulative elapsed idle time using ClockTickInterval units (Cumulative Number of Time Units for all idle time in the array). | None | TRANSLATABLE= true |
| InstanceID | string |
| Description | string | Within the scope of the instantiating Namespace, InstanceID opaquely and uniquely identifies an instance of this class. In order to ensure uniqueness within the NameSpace, the value of InstanceID SHOULD be constructed using the following 'preferred' algorithm:
<OrgID>:<LocalID>
Where <OrgID> and <LocalID> are separated by a colon ':', and where <OrgID> MUST include a copyrighted, trademarked or otherwise unique name that is owned by the business entity creating/defining the InstanceID, or is a registered ID that is assigned to the business entity by a recognized global authority (This is similar to the <Schema Name>_<Class Name> structure of Schema class names.) In addition, to ensure uniqueness <OrgID> MUST NOT contain a colon (':'). When using this algorithm, the first colon to appear in InstanceID MUST appear between <OrgID> and <LocalID>.
<LocalID> is chosen by the business entity and SHOULD not be re-used to identify different underlying (real-world) elements. If the above 'preferred' algorithm is not used, the defining entity MUST assure that the resultant InstanceID is not re-used across any InstanceIDs produced by this or other providers for this instance's NameSpace.
For DMTF defined instances, the 'preferred' algorithm MUST be used with the <OrgID> set to 'CIM'. | None | TRANSLATABLE= true |

| IOTimeCounter | uint64 |

| Description | string | The cumulative elapsed I/O time (number of Clock Tick Intervals) for all I/Os as defined in 'Total I/Os'.
