When more than one Teradata Fabric Manager instances are installed, cluster the Teradata Fabric Manager instances for high availability and scalability. Clustering makes sure that all Teradata Fabric Manager instances have the same configuration and each instance can administer and monitor Teradata Fabric. Create multiple Teradata Fabric Manager clusters to maintain separate production and test environments.
When a cluster is present, failover and recovery of a Teradata Fabric Manager instance is automatic. If one instance goes offline, the other instances in the cluster take over the workload of the failed instance. When the failed Teradata Fabric Manager is back online, any new configuration updates made while offline are automatically recovered and the workload resumes as it was before the failure.
