Cluster configuration¶
Fudo PAM cluster ensures uninterrupted access to servers in case of cluster node failure as well as enables implementing static load balancing scenarios.
Warning
- Cluster configuration does not facilitate data backup. If session data is deleted on one of the cluster nodes, it is also deleted from other nodes.
- Data model objects: safes, users, servers, accounts and listeners are replicated within the cluster and object instances must not be added on each node. In case the replication mechanism fails to copy objects to other nodes, contact technical support department.
Data replication between cluster nodes is highly customizable. The administrator can choose the node that the data will be replicated to as well as which data (data model objects/session data) is replicated.
In case of a node failure, user access requests will be picked up by another cluster node, determined by the redundancy group priority.
Current session data is replicated to other nodes while the connection is still ongoing.
If the node that fails was recording sessions, those sessions will be terminated…
…and users will have to reconnect.
A part of the session data from the node that malfunctioned, which has synchronized, can be accessed on the other nodes, but the session will be fully accessible once the node becomes operational and session data is synchronized between cluster nodes.
Session replication status can be verified by clicking the i icon on the sessions list.
