Configuring a Cascading Network Topology for Tenants that Connect Through a Local Gateway

Updated

There are some Commvault tenants that do not have access to the Internet and cannot connect to Commvault infrastructure network gateways. For such tenants, connections must be routed via backup network gateways that can connect to the Commvault network gateways. You can do this by creating a cascading topology.

Before You Begin

Enable the network gateway option (that is, the option labeled This computer is in DMZ and will work as Network Gateway) for all backup network gateway servers. For more information, see Network Options.

Procedure

  1. Using the procedure found in Adding a Smart Server Group, create Server Group A, which will contain all tenant servers, as follows:

    Note: Using the following rules, you can add multiple tenants in the same server group. The server group will create a route with a backup network gateway that is part of same company. It won’t create a route with any other tenant’s backup network gateway server.

    1. From automatic association rules for server groups, select the following rules (in the Match drop-down list select all):

      • Company Installed Client Association equal to (Company 1 – Select tenant company from drop-down list), and then Save.

      • Add another rule: Company Installed Client Association equal to (Company 2 – Select tenant company from drop-down list)

      • Add another rule: Company Installed Client Association equal to (Company 3 – Select tenant company from drop-down list)

      • Etc.

    2. Add a new Rule Group, select Client acts as proxy is false, and then click Save.

    3. Add a new rule, select Client equal to Installed, and then click Save.

  2. Using the procedure found in Adding a Smart Server Group, create Server Group B, which will contain all tenant backup network gateway clients that have Internet access to Commvault network gateways, as follows:

    1. Select the following rules (in the Match drop-down list, select all):

      • Company Installed Client Association equal to (Company 1 – Select tenant company from drop down)

      • Company Installed Client Association equal to (Company 2 – Select tenant company from drop down)

      • Company Installed Client Association equal to (Company 3 – Select tenant company from drop down)

      • Etc.

    2. Similarly, add all required tenant company rules.

    3. Add a new Rule Group, and then select Client acts as proxy is true.

    4. In the Match drop-down list for this rule group, select all.

    5. Similarly, add all required tenant company rules.

    6. Add a new Rule Group, and then Select Client acts as proxy is true.

    7. In the Match drop-down list for this rule group, select all.

  3. Using the procedure found in Configuring Cascading Network Gateway Connections Using Predefined Network Topologies - Client Type is Servers, create a new cascading network gateway topology using the above groups, as follows:

    • In the Servers list, select Server Group A created in Step 1, above, which contains all tenant servers.

    • In the Server gateways list, select Server Group B created in Step 2, above, which contains all tenant backup network gateways.

    • In the Network gateways list, select the Commvault infrastructure network gateways group.

    • In the Infrastructure machines list, select a server group that contains the CommServe computer and all of the MediaAgents required to back up the tenant's clients that are present in Server Group A.
