This test auto-discovers the nodes configured on the IBM Storewize v7000 storage system, and for each node, reports the data sent and received by that node and the latency of the node when receiving and sending data. Besides revealing the load on each node, this will also point you to those nodes that are most likely to experience an overload soon, and those nodes that are sending/receiving data much slower than the other nodes. Based on the results reported by this test, you can investigate the reason why certain nodes delay I/O processing, and initiate measures to eliminate the reasons; in addition, you can also fine-tune the load-balancing algorithm of the cluster to ensure that load is uniformly distributed across nodes.

This page depicts the default parameters that need to be configured for the IBMV7000NodeTest.

• 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.
