- NDS replicasearch for term
Novell Directory Services replicaA copy of an NDS partition.For the NDS database to be distributed across a network, it must be stored on many servers. Rather than storing a copy of the whole NDS database on each server, NDS replicas of each partition are stored on many servers throughout the network. Administrators can create an unlimited number of NDS replicas for each partition and store them on any server. NDS replicas serve two purposes: they eliminate single points of failure, and they provide faster access to information for users across WAN links.Types of NDS replicas include master replicas, read/write replicas, read-only replicas, and subordinate reference replicas. To maintain fault tolerance, the replicas of a partition are periodically (and automatically) updated, or synchronized.
