Distributed File System Replication (DFS-R) Scale Limits

The following list provides a set of scalability guidelines that have been tested by Microsoft:

• Each server can be a member of up to 256 replication groups.

• Each replication group can contain up to 256 replicated folders.

• Each server can have up to 256 connections (for example, 128 incoming connections and 128 outgoing connections).

• On each server, the result of the following formula should be kept to 1024 or fewer: (number of replicated folders in replication groupx * number of simultaneously replicating connections in replication groupx) + (number of replicated folders in replication groupy * number of simultaneously replicating connections in replication groupy) + (number of replicated ...
