To ensure complete system redundancy, the NSX Advanced Load Balancer Controller must be highly available. To provide high availability (HA) for the Controller, add two additional NSX Advanced Load Balancer Controller nodes to create a three-node Controller cluster.

HA of the NSX Advanced Load Balancer Controller requires three separate Controller instances configured as a 3-node cluster. Start with a single-node NSX Advanced Load Balancer Controller deployment and use the following steps to add two additional NSX Advanced Load Balancer Controller nodes to form a 3-node cluster.

Note:

If the cluster is already deployed and you want to modify its node membership or dismantle the cluster, see Changing NSX Advanced Load Balancer ControllerCluster Configuration.

Prerequisites for Cluster Deployment

Leader node
  • The leader can be any single node with configuration or without configuration.

  • The leader can have SEs connected.

  • The node must have a static IP address.

    • Using DHCP can cause issues when nodes reboot and their IP addresses change.

    • The current release does not support the use of hostnames for cluster configuration.

Follower nodes
  • An NSX Advanced Load Balancer Controller cluster can have three nodes, one leader node and two follower nodes.

  • Follower nodes are expected to have no configuration and no changes to the NSX Advanced Load Balancer login credentials.

  • Follower nodes are expected to be running the same NSX Advanced Load Balancer base+patch version as the leader.

  • A follower typically is a VM or Mesos container created from the the NSX Advanced Load Balancer Controller installation package.

  • Each follower node must have a static IP address.
