Prepare the environment for converting a Single Engine to a Engine Cluster

Make sure your environment meets these requirements before you convert a Single Engine to a Engine Cluster.

Steps

  1. Select one Single Engine element to convert to a cluster.
  2. Make sure that you have a license for each node in the Engine Cluster.
  3. If you are not using identical hardware, make sure that the performance levels match your needs.
    You can use hardware with different performance levels for load-balanced clustering. For standby clustering, the performance level of each node must be high enough to handle all traffic.
  4. Make sure that enough IP addresses are available in the network, especially if the Single Engine is managed remotely.
    Each node in the Engine Cluster needs at least one dedicated IP address for its management communications. Also, the traffic that the nodes inspect requires at least one dedicated IP address per cluster.
  5. Make sure that the Secure SD-WAN Engine hardware is running software versions that are compatible with the SD-WAN Manager, and that both Secure SD-WAN Engines are running the same version.
  6. If the Secure SD-WAN Engine hardware that you are adding to the cluster already has a working configuration from previous use, return it to the initial configuration state using the Secure SD-WAN Configuration Wizard (sg-reconfigure) on the command line.
    Do not establish a connection with the Management Server before the Engine Cluster element is ready.
    CAUTION:
    If the Engine has a working configuration, it goes online and processes traffic when you turn it on to configure it for the Engine Cluster.
  7. Connect the network cables to the new Secure SD-WAN Engine hardware and turn it on.
