Having a multi-node cluster of NSX Edges helps ensure that at least one NSX Edge is always available. In order to create a tier-0 logical router or a tier-1 router with NAT, you must associate it with an NSX Edge cluster. Therefore, even if you have only one NSX Edge, it must still belong to an NSX Edge cluster to be useful.

About this task

An NSX Edge transport node can be added to only one NSX Edge cluster.

An NSX Edge cluster can be used to back multiple logical routers.

After creating the NSX Edge cluster, you can later edit it to add additional NSX Edges.

Prerequisites

  • Install at least one NSX Edge node.

  • Join the NSX Edges with the management plane.

  • Add the NSX Edges as transport nodes.

  • Optionally, create an NSX Edge cluster profile for high availability (HA) at Fabric > Profiles > Edge Cluster Profiles. You can also use the default NSX Edge cluster profile.

Procedure

  1. In the NSX Manager UI, navigate to Fabric > Nodes > Edge Clusters.
  2. Type the NSX Edge cluster a name.
  3. Select an NSX Edge cluster profile.
  4. Click Edit and select either Physical Machine or Virtual Machine.

    Physical Machine refers to NSX Edges that are installed on bare metal. Virtual Machine refers to NSX Edges that are installed as virtual machines/appliances.

  5. For Virtual Machine, select either NSX Edge Node or Public Cloud Gateway Node from the Member Type drop-down menu.

    If the virtual machine is deployed in a public cloud environment, select Public Cloud Gateway otherwise select NSX Edge Node.

  6. From the Available column, select NSX Edges and click the right-arrow to move them to the Selected column.

What to do next

You can now build logical network topologies and configure services. See the NSX-T Administration Guide.
