|test purpose  | This test case will check the parameters which could decide  |
|              | several models and each model has its specified task to      |
|              | measure. The test purposes are to measure disk size, block   |
|              | size and disk utilization. With the test results, we could   |
|              | evaluate the storage capacity of the host.                   |
