You can configure a cluster in which both gateways are managed by Quantum Spark Portal. Make sure the gateways are connected to Quantum Spark Portal before you create the cluster.
A cluster supported by Quantum Spark Portal is very similar to a locally managed cluster. One member is Active, and the other is Standby.
Note – When the cluster is managed by Quantum Spark Portal, connections are not synchronized. In the event of cluster failover, you must re-establish the connections.
