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 stateful services such as NAT, load balancer, and so on. 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.

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.
  • Verify that the NSX Edge node is stable, with all services up and running and all groups are stable, before joining the node to the cluster.
  • 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). You can also use the default NSX Edge cluster profile.
  • To ensure successful failover in failure scenarios, each standby NSX Edge node must be connected to a hypervisor.

Procedure

  1. From a browser, log in with admin privileges to an NSX Manager at https://<nsx-manager-ip-address>.
  2. Select System > Fabric > Nodes > Edge Clusters > Add.
  3. Enter the NSX Edge cluster a name.
  4. Select an NSX Edge cluster profile from the drop-down menu.
  5. In Member Type drop-down menu, select either Edge Node if the virtual machine is deployed on-premises or Public Cloud Gateway if the virtual machine is deployed in a public cloud.
  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 Data Center Administration Guide.
