Types of Replica

A suffix that participates in replication is called a replica. There are three kinds of replica:

A single instance of Directory Server can be configured to manage several replicas.

A replica can act as a supplier of updates, or a consumer of updates, or both.

A replica can be promoted or demoted to change its behavior with respect to other replicas. Dedicated consumers can be promoted to hubs, and hubs can be promoted to masters. Masters can be demoted to hubs, and hubs can be demoted to dedicated consumers.

A server that contains a consumer replica only is called a dedicated consumer.
