********************************** Drive Usage Per Hour ********************************


* The drive usage is given by the amount of time a drive is used for either

* writing or for reading purposes. These details can be obtained from the

* MMDriveHistory table. The time at which a write or a read operation has

* started is given by TimeStart column. Hence we can obtain the amount of time

* a drive is in use by summing up the DataWriteDurationSec+DataReadDurationSec

* grouping by the DriveId. Using the above sum we can find the percentage of

* time the drive is in use over one hour and twenty four hours duration.



************************* Throughput of the Drive in GB/Hr *****************************


* The throughput of a drive is calculated based on the amount of data has been

* read or written to a drive in an hour. The columns DataWritten and DataRead in

* the same table as above gives the required data. This sum DataWritten+DataRead

* is again averaged for the last one hour and for twenty four hours.
