A “Cluster of Clusters” where one cluster contains the single active, writable primary. All other clusters and nodes are passive and read-only. Typically two or more clusters.
In the Tungsten Composite Active/Passive Cluster topology (Active/Passive), there is a single writeable primary node across all sites, and all writes are directed to that primary. The Connectors are multi-site aware and will automatically react to a site failover. Replication flows in one direction only, from the current active primary cluster to the passive DR cluster(s).
