Replica InstanceReplica Instance
A replica instance provides deployment-level redundancy of the primary instance. With a few exceptions, you can view, but not update, administrative data on a replica instance.
A replica instance provides the following benefits:
-
Real-time mirror of all user and system data
-
Failover authentication if the primary instance becomes unresponsive
-
Improved performance by load balancing authentication requests to multiple instances
-
Ability to deploy a replica instance at a remote location
-
Ability to recover administrative capabilities through replica promotion if the primary instance becomes unresponsive
-
Administrators can clear PINs and provide emergency access to users
Note: If the primary instance has an “Out-of-Sync” replication status, for any reason, resynchronizing the deployment removes any administrative changes that occurred on a replica instance. For example, you may need to regenerate an offline emergency access tokencode that was generated on a replica instance.
Although a replica instance is optional, RSA recommends that you deploy both a primary and a replica instance. The RSA Authentication Manager Base Server license and the Enterprise Server license both include permission to deploy a replica instance.
