Adding Controllers to the Cluster
iSTAR Ultra Installation and Configuration Guide 3–11
Adding Controllers to the Cluster
Follow these guidelines when adding controllers to a cluster.

A controller must be assigned to a cluster before the controller can communicate with the
host, master, or other controllers.
Use the Cluster
window in the C•CURE System Administration Application to add
controllers to a cluster. When added to a cluster, the controller becomes a cluster member.

One controller can comprise a cluster. You can configure a controller as its own cluster by
configuring a cluster that includes only the controller and specifying that controller as the
master.

A cluster member communicates with other cluster members through the master.

A cluster communicates with the C•CURE host via the cluster’s primary or secondary
path.

A cluster communicates with other clusters and with apC panels via the C•CURE host.

A cluster can communicate with the C•CURE server across a WAN. You can configure
clusters that are spread across WAN topologies.
