Step 6. Configure Network Extension Appliances

At the Network Extension step of the wizard, Veeam Backup & Replication will display network extension appliance that will be deployed on the tenant's side. This network extension appliance will be used for establishing and maintaining connection between production VMs and VM replicas on the cloud host after partial site failover.

In the Network extension appliances section of the Network Extension step of the wizard, you can view default network extension settings, edit settings for the network extension appliance and add one or several network extension appliances in case there are multiple IP networks in your production environment. To learn more, see Network Extension Appliance.

Step 6. Configure Network Extension Appliances Note:

Consider the following.

  • If you do not plan to perform partial site failover, you can remove the network extension appliance from the Network extension appliances list and proceed to the next step of the wizard. In this case, Veeam Backup & Replication will not deploy the network extension appliance on the source virtualization host.
  • If you add the SP using credentials of the vCloud Director tenant account, and the SP uses an NSX Edge Gateway or IPsec VPN connection to enable network access to your VM replicas after failover, you do not need to deploy the network extension appliance. Click Remove next to the Network extension appliances list, and then click Apply to proceed to the next step of the wizard.

The process of configuring the network extension appliance differs depending on the virtualization platform whose VMs you want to replicate to the cloud: VMware vSphere or Microsoft Hyper-V.

Step 6. Configure Network Extension Appliances 

Configuring Network Extension Appliance for VMware vSphere

To configure the network extension appliance that will deployed on the source VMware vSphere host:

  1. Open the Network Extension Appliance Configuration window. To do this, do one of the following:
  1. In the Network Extension Appliance Configuration window, in the Host section, click Choose and select the host on which the network extension appliance must be deployed. That is the source host from which your production VMs will be replicated to the cloud host.
  2. In the Resource pool section, click Choose and select the resource pool in which the network extension appliance VM must be placed.
  3. In the Datastore section, click Choose and select the datastore on which to keep files of the network extension appliance VM.

Step 6. Configure Network Extension Appliances Note:

You cannot deploy a network extension appliance on the following types of storage:

  • VMware vSAN
  • VMware Virtual Volumes (VVol)
  • Datastore Cluster

  1. In the Network section, click Choose and select the virtual switch to which production VMs on the source host are connected.
  2. Specify the IP addressing settings for the appliance:
  1. Click OK.

Step 6. Configure Network Extension Appliances 

Configuring Network Extension Appliance for Microsoft Hyper-V

To configure the network extension appliance that will deployed on the source Microsoft Hyper-V host:

  1. Open the Network Extension Appliance Configuration window. To do this, do one of the following:
  1. In the Network Extension Appliance Configuration window, in the Host section, click Choose and select the host on which the network extension appliance must be deployed. That is the source host from which your production VMs will be replicated to the cloud host.
  2. In the Folder section, click Choose and specify the path to the folder on the storage to keep files of the network extension appliance VM.
  3. In the Network section, click Choose and select the virtual switch to which production VMs on the source host are connected.
  4. In the VLAN ID field, specify the VLAN ID of the network on the selected virtual switch to which VMs that you plan to replicate are connected.
  5. Specify the IP addressing settings for the appliance:
  1. Click OK.
