CLUSTERS


What is a Domino cluster?
An IBM® Lotus® Domino® cluster is a group of two or more servers that provides users with constant access to data, balances the workload between servers, improves server performance, and maintains performance when you increase the size of your enterprise. The servers in a cluster contain replicas of databases that you want to be readily available to users at all times. If a user tries to access a database on a cluster server that is not available, Domino opens a replica of that database on a different cluster server, if a replica is available. Domino continuously synchronizes databases so that whichever replica a user opens, the information is always the same.

IBM Lotus Notes® clients can access all Domino cluster servers. HTTP clients (Internet browsers) can access only Domino Web servers in a Domino cluster.
