In a high availability cluster with load balancing, one appliance acts as the active primary appliance, one acts as the passive primary appliance, and any additional appliances act as secondary appliances. The passive primary appliance takes over as the active primary appliance if the active primary appliance encounters an error and is unable to recover. The secondary appliances process submissions allocated by the active primary appliance for performance improvement.

Deploy this cluster configuration if you want to combine the benefits of high availability clustering and load-balancing clustering.

The following figure shows Deep Discovery Analyzer appliances deployed in a high availability cluster configuration and how integrating products communicate with Deep Discovery Analyzer.
