ClusterCATS is an embedded installation option in the ColdFusion Server installation program. To install the ClusterCATS load balancing and high availability capabilities on each of your servers, run the ColdFusion Server installation program on each server that will be part of your cluster and choose the Load Balancing and High Availability install option. Also, run the installation program to install ClusterCATS on a separate, non-clustered machine from which you will administer your clusters using the ClusterCATS Explorer.

Typically, you want all of the servers in your cluster to be configured for failover, particularly if they have the same processing capacity. However, if you have a mixed server environment with some high capacity servers and several lower capacity servers, you may not want the less powerful machines to accept the additional load of unavailable servers in the cluster.
