       "A subclass of StatisticalData which identifies individual "
       "statistics for an element of a block storage system. This "
       "class defines the metrics that MAY be kept for managed "
       "elements of the system.")]
class CIM_BlockStorageStatisticalData : CIM_StatisticalData {

      [Required, Description (
          "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. \n"
          "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 "
