You install the drivers on each cluster, with multiple instances in the driver set on Cluster One, but
only a single instance in the peer clusters, as shown in

In the four-cluster business continuity cluster, you can set up the fourth node to talk to any one of the
other three, making sure to avoid a configuration that results in a synchronization loop. This might
be desirable if Cluster One and Cluster Two are in one tree (or user object partition), and Cluster
Three and Cluster Four are in a second tree (or user object partition). In this case, you could set up
channels for the Cluster Resource Synchronization driver between Cluster One and Cluster Two,
between Cluster One and Cluster Three, and between Cluster Three and Cluster Four. You must
assign a separate port for each of these channels, as shown in
instance of the User Object Synchronization driver on a different port between the two clusters that
communicate across the two trees (or across the two User object partitions).
