| 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 |

| Generation | uint64 |
| Description | string | Generation is an optional, monotonically increasing property that may be used to identify a particular generation of the resource represented by this class.
If Generation is supported by the implementation, its value shall not be null.
Except as otherwise specified, a value (including null) of Generation specified at creation time shall be replaced by null if Generation is not supported by the implementation or shall be a, (possibly different), non-null value if the implementation does support Generation.
After creation and if supported, Generation shall be updated, at least once per access, whenever the represented resource is modified, regardless of the source of the modification.
Note: the Generation value only needs to be updated once between references, even if the resource is updated many times. The key point is to assure that it will be different if there have been updates, not to count each update.
Note: unless otherwise specified, the value of Generation within one instance is not required to be coordinated with the value of Generation in any other instance.
Note:the semantics of the instance, (as defined by its creation class), define the underlying resource. That underlying resource may be a collection or aggregation of resources. And, in that case, the semantics of the instance further define when updates to constituent resources also require updates to the Generation of the collective resource. Default behavior of composite aggregations should be to update the Generation of the composite whenever the Generation of a component is updated.
Subclasses may define additional requirements for updates on some or all of related instances.
For a particular instance, the value of Generation may wrap through zero, but the elapsed time between wraps shall be greater than 10's of years.
This class does not require Generation to be unique across instances of other classes nor across instances of the same class that have different keys. Generation shall be different across power cycles, resets, or reboots if any of those actions results in an update. Generation may be different across power cycles, resets, or reboots if those actions do not result in an update. If the Generation property of an instance is non-null, and if any attempt to update the instance includes the Generation property, then if it doesn't match the current value, the update shall fail.
The usage of this property is intended to be further specified by applicable management profiles.
Typically, a client will read the value of this property and then supply that value as input to an operation that modifies the instance in some means. This may be via an explicit parameter in an extrinsic method or via an embedded value in an extrinsic method or intrinsic operation.
For example: a profile may require that an intrinsic instance modification supply the Generation property and that it must match for the modification to succeed. | 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 |
