Cassandra clustering and data replication overview

With Session Manager Release 7.0.1, if the Enable Data Storage Cluster field on the Session Manager Administration page is selected, Session Managers are added to the Cassandra database cluster. Each Cassandra is running in a cluster of 1 node and there are N clusters, where N is the number of Session Managers.

The Cassandra nodes are configured to have a single cluster of Cassandra nodes. If the Enable Data Storage Cluster field is not selected, all the Cassandra nodes run in standalone mode.

Cassandra clustering is done only when Avaya Aura® Device Services (AADS) servers are configured and paired with Session Manager.

Cassandra data distribution uses the administration on the User Data center page to identify the Session Manager instances that are within the same datacenter.

For administering Cassandra data distribution:

  1. Enable data storage clustering.

  2. Create a data center.

  3. Assign co-located Session Managers to the data center.

  4. Add the AADS instance to the inventory.

  5. Pair a Session Manager instance with an AADS node.
