Setting Up a Cascading Dual Network Gateways Topology

You can define multiple dual-network gateway paths between two CommCell entities. The dual-network gateway paths can be set as alternate routes so that the two CommCell entities can connect to each other. The following diagram provides a representation of this configuration:

Use this procedure to configure incoming and outgoing connections on the six CommCell entities that are shown in the diagram: CommServe computer, Network gateway 1 through Network gateway 4, and Client.

Before You Begin

The Commvault network gateway computers must be configured.

Procedure

1. Step 1: Create four server groups

   Create four server groups as follows:

   1. Create a server group named Clients, and then add all of the clients to the group.

   2. Create a server group named CS/MA, and then add the CommServe and internal MediaAgents to the group.

   3. Create a server group named Internal Network Gateways, and then add the internal network gateways (for example, Network Gateway 1 and Network Gateway 3 in the diagram above) to the group.

   4. Create a server group named External Network Gateways, and then add the external network gateways (for example, Network Gateway 2 and Network Gateway 4 in the diagram above) to the group.

2. Step 2: Create the first network topology

   Create the first network topology as follows:

   1. From the Command Center navigation pane, go to Administration > Network > Network Topologies.

   2. From the Network topologies pane, click Add topology.

      The Add topology dialog box is displayed.

   3. In the Name field, enter a name for this topology.

   4. For Client type, select Servers.

   5. From the Topology type list, select Network Gateway.

   6. Select the server groups as follows:

      1. For Trusted Server group 1, select CS/MA.

      2. For Trusted Server group 2, select External Proxies.

      3. For Network gateway or DMZ group, select Internal Proxies.

   7. Click Save.

3. Step 3: Create the second network topology

   Create the second network topology as follows:

   1. From the Command Center navigation pane, go to Administration > Network > Network Topologies.

   2. From the Network topologies pane, click Add topology.

      The Add topology dialog box is displayed.

   3. In the Name field, enter a name for this topology.

   4. For Client type, select Servers.

   5. From the Topology type list, select Via proxy.

   6. Select the server groups as follows:

      1. For Trusted Server group 1, select Clients.

      2. For Trusted Server group 2, select Internal Proxies.

      3. For Proxy/DMZ group, select External Proxies.

   7. Click Save.

4. Step 4: Create the third network topology

   Create the third network topology as follows:

   1. From the Command Center navigation pane, go to Administration > Network > Network Topologies.

   2. From the Network topologies pane, click Add topology.

      The Add topology dialog box is displayed.

   3. In the Name field, enter a name for this topology.

   4. For Client type, select Servers.

   5. From the Topology type list, select Via proxy.

   6. Select the server groups as follows:

      1. For Trusted Server group 1, select Clients.

      2. For Trusted Server group 2, select CS/MA.

      3. For Proxy/DMZ group, select External Proxies.

   7. Click Save.

5. Step 5: Create the fourth network topology

   Create the fourth network topology as follows:

   1. From the Command Center navigation pane, go to Administration > Network > Network Topologies.

   2. From the Network topologies pane, click Add topology.

      The Add topology dialog box is displayed.

   3. In the Name field, enter a name for this topology.

   4. For Client type, select Servers.

   5. From the Topology type list, select Via proxy.

   6. Select the server groups as follows:

      1. For Trusted Server group 1, select CS/MA.

      2. For Trusted Server group 2, select Clients.

      3. For Proxy/DMZ group, select Internal Proxies.

   7. Click Save.

6. Step 6: Push network configurations

   Push the network configurations for each network topology you just created, as follows:

   1. From the Command Center navigation pane, go to Administration > Network > Network Topologies.

   2. From the Network topologies pane, click the Actions button for a topology you just created, and then click Push network configuration.

   3. Repeat Step 2 for each network topology you just created.
