Now that the parent Virtual Service is configured, the SubVSs can be added. We will need to add a SubVS for each of the workloads/applications defined earlier. To add the SubVSs, follow the steps below in the LoadMaster WUI.

  1. In the Virtual Service modify screen, expand the Real Servers section.

  2. Click Add SubVS.
  3. Click OK.
    Note: As the first SubVS has been added, it is now possible to enable Content Switching.
  4. In the SubVSs section, click Modify to configure the SubVS.

  5. In the Basic Properties section, enter a recognizable SubVS Name, for example OWA and click Set Nickname.

  6. In the Standard Options section, configure the required Persistence Options for the relevant application.
    Note: There is no persistence required for Exchange 2013.
  7. Select the relevant Scheduling Method.

  8. In the Real Servers section, configure the Real Server Check Parameters. This defines the health check that is executed for this Virtual Service. For Exchange, the following settings could be entered:

    Checked Port: 443

    URL: /owa/healthcheck.htm

    Use HTTP/1.1: Enabled

    HTTP Method: GET

  9. Click Add New.

  10. Enter the Real Server’s address in the Real Server Address text box.
  11. Enter the relevant Port.
    Note: For Lync, the Port might need to be changed to 4443.
  12. Click Add This Real Server.
  13. Repeat steps 12 to 14 above for each Real Server that needs to be added to this SubVS.
  14. When all of the Real Servers have been added, click Back to return to the SubVS properties screen.
  15. Click Back to return to the parent Virtual Service properties screen.
  16. Expand the Advanced Properties section.

  17. Click Enable.

  18. Click None.

  19. Select the relevant rule and click Add.

    Note: If the SubVS is for Exchange, select the OWA rule.
  20. Now, create a SubVS for each of the other workloads by repeating steps 1 to 19 above. Steps 4 and 5 are no longer required as Content Switching has already been enabled for the parent Virtual Service.

Once everything is set up, the overview of the Virtual Services will show something similar to the screenshot above.

When you click the blue IP address, a breakdown of the different SubVSs will be displayed; one for each workload with each having its specific health check.
