Testing Network Performance Between MediaAgents in a Storage Policy

Use this mode to test available bandwidth between the MediaAgents associated to a storage policy. If you prefer, you can limit the testing to a single copy of the storage policy.

Note: The default values are used for the test options that you can individually set in Host-to-Host mode.

Before You Begin

  • Download the CvNetworkTestTool GUI workflow from the Commvault Store. For instructions, see Download Workflows from Commvault Store.
  • If the MediaAgents are separated from each other by one or more firewalls, make sure the needed server port is open on those firewalls (port 25000 is the default).


  1. From the CommCell Browser, click Workflows, and then right-click CvNetworkTestTool GUI > All Tasks > Execute.

    The CvNetworkTestTool GUI dialog box appears.

  2. From the Mode of execution list, select MediaAgents in a Storage Policy and click OK.
  3. In the Enter Storage Policy dialog box, select the storage policy name and click Next.
  4. In the Enter Copy dialog box, select a storage policy copy to limit the test to the MediaAgents that are associated with the copy, and then click Finish.

    The test sends 25,000 blocks of 16 KB each.

  5. When the test has completed, retrieve the results from your email Inbox. Open the attached CSV file in an appropriate application, such as a spreadsheet, to see the results.

Note: The network throughput results are shown in MB/sec (megabytes per second).
