For each VDisk in the IBM Storwize v7000 storage system, this test monitors the I/O load on the VDisk, reports how well the cache services the read and write I/O load, and in the process, indicates whether/not the cache has been effectively utilized. I/O processing bottlenecks (if any) in the VDisk and inoptimal cache usage can thus be detected and the reasons for the same investigated.

This page depicts the default parameters that need to be configured for the IBMV7000VDCacheTest.

• The TEST PERIOD list box helps the user to decide how often this test needs to be executed.

• Specify the duration (in seconds) beyond which the test will timeout in the TIMEOUT text box. The default value is 60 seconds.

• Once the necessary values have been entered, clicking on the Update button will register the changes made.

When changing default configurations of tests, the values with “$” indicate variables that will be replaced by the eG system according to the specific server being managed - for instance, $hostName is the host/nickname of the target host, $port is the port number of the server being monitored. E.g., for a server xyz:80, $hostName will be changed automatically by the eG manager to “xyz” and $port will be changed to “80” when configuring a test.
