To add capacity and to enable system failover, you can cluster a group of Identity Servers by clustering a group of Access Manager appliances. The Access Manager appliance cluster will automatically cluster the group of Identity Servers. You can also configure the cluster to support session failover, so that users don’t need to reauthenticate when an Identity Server goes down.
Enable session failover so users do not need to re-authenticate when an Identity Server goes down. See Configuring Session Failover.
Modify the name of the cluster or edit communication details. See Editing Cluster Details.
