Configuring replication of Content Store data between clusters

Last Updated : Feb 16, 2022 |

About this task

Content Store replication is a one-way data copy that only flows from the master cluster to the replica clusters. No changes are required on the master cluster to enable replication. Replica clusters connect to the master cluster using the Replication Account for authentication.

Content Store replication between clusters provides the following capabilities:
  • Single point provisioning: Many clusters with common data, for example, announcement recordings, can be provisioned from a single designated master cluster. Replication ensures the data is copied from the master cluster to the replica clusters.

  • Geographic-redundancy: A duplicate cluster at an alternate location can be maintained as a contingency cluster to receive traffic when the primary location becomes unavailable. The contingency cluster is a replica of the master cluster and receives all the Content Store application data in real-time so that it is ready to take over with the latest content. A contingency cluster must not receive traffic or provisioning changes when in standby.

    Perform the following procedure to enable replication of Content Store data between N+1 Load Sharing Cluster or 1+1 High Availability Clusters.

Before you begin

  • Configure one Avaya Aura® MS cluster to function as the master cluster.

  • Configure one Avaya Aura® MS cluster to function as the replica cluster.

  • Obtain the UUID and the IP address of the Primary server.

  • Obtain the username and the password of the Replication Account.

Procedure

  1. Access the Element Manager (EM) for the Primary server in the replica cluster and navigate to EM > Cluster Configuration > Replication Settings.
  2. In Master Cluster Primary Node Address, type the address of the Primary server of the master cluster.
    Note:

    A maximum of four replication clusters can point to one master cluster in a star topology. Chain topologies do not have a length limit and can be combined with star topologies.

  3. Click Save.

    The Avaya Aura® MS system activates the replication immediately. The entire content data on the master cluster is copied to the replica cluster.

    If the system raises any critical mirror connection alarms, ensure that you have used the correct address and the Replication Account username and password are the same for all of the clusters.

    If you have not enabled Configuration Replication within the cluster, you must repeat Step 1 to Step 3 for each node in the replica cluster.
