This test auto-discovers the volumes in the NexentaStor device and reports how well each volume handles the I/O requests it receives. In the process, the test points administrators to those volumes that are slow in I/O processing.

The default parameters associated with this test are:

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

• Specify the host for which this test is to be configured in the HOST text box.

• Specify the port at which the specified HOST listens in the PORT text box. By default, this is NULL.

• In the TIMEOUT text box, specify the duration (in seconds) within which the test should wait for a response from the storage device. The default is 10 seconds.

• If multiple components of the same component type are awaiting configuration, then an APPLY TO OTHER COMPONENTS check box will appear in this page. Clicking on this check box will allow you to apply the configuration to all/selected components of that type.

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

When changing the configuration for specific servers, a “*” beside the text box corresponding to the parameter signifies that these values have to be manually configured by the user. The parameter values that require to be configured will typically be prefixed with a “$” or contain a series of “*”. A value of "none" in the parameter value indicates that the corresponding parameter value can be changed if required.
