!!! Overview
The user-defined Partition or [{$pagename}] is the most common type of partition, and it is likely the type you are already familiar with. 

Any DS server may hold a copy of a user-defined replica. Changes to a user-defined partition must be distributed to other servers that hold a copy of the same user-defined partition. 

When these changes occur, they are replicated under the control of the [EDirectory Synchronization] Process.

A [Edirectory Replica] is a copy of a user-defined partition that is placed on an NDS server. 

There is no limit to how many [Edirectory Replicas] a server can hold, subject to disk space availability. 

Only one replica of the same user-defined partition can exist on a server.
