Drive Operation Test
For each drive on the storage device, this test reports the speed of the drive and the rate of tag creation on the dive.
Target of the test : A Hitachi AMS storage device
Agent deploying the test : A remote agent
Outputs of the test : One set of results for each drive on the Hitachi AMS device being monitored.

|
Operating rate |
Indicates the speed, in percentage, with which this drive processes read/write requests. |
Percent |
A high value for this measure indicates that a large number of read/write operations have been performed on this drive. Comparing the value of this measure across drives will enable you to detect issues in load balancing across drives, accurately identify overloaded drives, and initiate relevant remedial measures. |
