You isolate the network traffic to the vSphere Replication Server adding a dedicated network adapter to the vSphere Replication VM to handle data from each management ESXi host.

By default, the vSphere Replication appliance has one virtual machine network adapter that is used by the vSphere Replication Server for both replication traffic and by vCenter Server for virtual machine management. To isolate the replication traffic, you add a second adapter to the appliances in both regions and configure them for replication traffic.

Procedure

  1. Log in to vCenter Server by using the vSphere Web Client.
    1. Open a Web browser and go to https://sfo01m01vc01.sfo01.rainpole.local/vsphere-client.
    2. Log in using the following credentials.
      Setting Value
      User name administrator@vsphere.local
      Password vsphere_admin_password
  2. Shut down the vSphere Replication appliance to allow changes in the hardware configuration.
    1. In the Navigator pane, click Hosts and Clusters.
    2. Expand the entire sfo01m01vc01.sfo01.rainpole.local tree.
    3. Right-click the sfo01m01vrms01 virtual appliance and select Power > Shut Down Guest OS.
    4. In the Confirm Guest Shut Down dialog box, click Yes to proceed.
  3. Add a VM network adapter to the vSphere Replication virtual appliance for replication traffic only.
    1. Right-click the sfo01m01vrms01 virtual appliance and select Edit Settings.
    2. In the Edit Settings dialog box, click Yes to proceed.
    3. In the Edit Settings dialog box, from the New device drop-down menu, select Network, and click Add.
    4. From the New Network device drop-down menu, select sfo01-m01-vds01-replication and click OK.
    5. Right-click the sfo01m01vrms01 virtual appliance and select Power > Power On.
    6. In the Confirm Power On dialog box, click Yes to proceed and wait until the appliance is up and running.
  4. Log in to the Virtual Appliance Management Interface of the vSphere Replication appliance.
    1. Open a Web browser and go to https://sfo01m01vrms01.sfo01.rainpole.local:5480.
    2. Log in using the following credentials.
      Settings Value
      User name root
      Password vr_sfo_root_password
  5. Configure the network settings of the new network adapter eth1.
    1. Click the Network tab and click Address.
    2. Under eth1 info, enter the following settings and click Save Settings.
      Setting Value
      IPv4 Address Type Static
      IPv4 Address 172.16.16.71
      Netmask 255.255.255.0
      IPv6 Address Type Auto
    3. Click the VR tab and click Configuration.
    4. In the IP Address for Incoming Storage Traffic text box, enter 172.16.16.71 and click Apply Network Setting.
      172.16.16.71 is the IP address of the new network adapter that will handle replication traffic.
  6. Repeat the steps to reconfigure the lax01m01vrms01 vSphere Replication appliance in Region B, using the values from the following table.
    Setting Value
    Object to configure lax01m01vrms01
    Connect New Network Adapter To lax01-m01-vds01-replication
    URL of vSphere Replication Appliance https://lax01m01vrms01.lax01.rainpole.local:5480
    IPv4 Address Type Static
    IPv4 Address 172.17.16.71
    Netmask 255.255.255.0
    IP Address For Incoming Storage Traffic 172.17.16.71
  7. Log in to vCenter Server by using the vSphere Web Client.
    1. Open a Web browser and go to https://sfo01m01vc01.sfo01.rainpole.local/vsphere-client.
    2. Log in using the following credentials.
      Setting Value
      User name administrator@vsphere.local
      Password vsphere_admin_password
  8. On the vSphere Replication appliances, add static network routes to the hosts in the other region.
    Appliance Host Name Source Gateway Target Network
    sfo01m01vrms01.sfo01.rainpole.local 172.16.16.253 172.17.16.0/24
    lax01m01vrms01.lax01.rainpole.local 172.17.16.253 172.16.16.0/24
    1. In the Navigator pane, click Hosts and Clusters.
    2. Expand the entire sfo01m01vc01.sfo01.rainpole.local tree.
    3. Right-click the sfo01m01vrms01 virtual appliance and select Open Console to open the console to the appliance.
    4. Press ALT+F2 to switch to the command prompt.
    5. Log in using the following credentials.
      Setting Value
      User name root
      Password vr_root_password
    6. Open the /etc/sysconfig/network/routes file using vi editor.
      vi /etc/sysconfig/network/routes
    7. Add the following line after the default gateway to create a route to the recovery region for the hosts in Region A or to the protected region for the hosts in Region B, and save the file.
      Region of the vSphere Replication Appliance Value
      Region A 172.17.16.0/24 172.16.16.253 dev eth1
      Region B 172.16.16.0/24 172.17.16.253 dev eth1
    8. Run the service network restart command.
    9. To verify the routing table, run the route -n command.
    10. Repeat the step on the vSphere Replication appliance in the other region.
