A read/write replica is a copy of the master replica and is the most common type of replica. Users can read and update its NDS information locally.
Read/write replicas cannot be split, deleted, or merged. To perform these functions, make your changes to the master replica. The related replicas will then be automatically regenerated.ly regenerated.

Master Replicas
Although many replicas of a partition can exist in the NDS database, only one is designated as the "master." A master replica is the first instance of the original partition information.
The master replica is the only one that can be used to make changes like splitting, deleting, or merging.
Note that when you change the structure of the master replica, replicas of the partition are automatically deleted and the succeeding partition generates new replicas to replace those deleted.

This lesson describes how the NDS database is able to be split into partitions and replicated for ease of use and access across the network.
This strategy reduces the chance that the entire NDS database will become inoperable at one time and provides users faster access to information across the network.

Replicas - Ensure Fault Tolerance
Replicas can help ensure fault tolerance by eliminating single points of failure.
For example, if a server disk crashes or a natural disaster occurs, a replica on a server in another location can allow users to log in and access information about objects in that partition.

Partitions and replicas are important parts of the
NetWare Directory Services (NDS) database.
Partitions are logical divisions of the NDS database for distribution across the network.
Replicas are copies of partition information that are stored throughout the network.
The effective planning of these components can increase the efficiency of the NDS database and accessibility of information across a NetWare v4.0 network and ensure system fault tolerance.

When a partition is generated, it includes the original container object and all subordinate containers and objects.
Note that because NDS does not include any information about the file system or the file system's directories and files, neither do NDS partitions.
