Clusterix is cluster software for Unix. It is intended for use with 2 machines for high availability services. For example, you can have a Web server with 2 nodes, or a database with shared disk. To put more than one service in high availability so that one service stays on one node and the second on the other node, you can simply make 2 installations of Clusterix in 2 different directories on the 2 nodes. When there is a failure of service on one node, the cluster system moves the service to the other node.
