Sun Cluster 3.1 8/05 and Sun Cluster Agents

Sun Cluster software provides high availability and scalability services for Java Enterprise System as well as for applications based on Java ES infrastructure.

A cluster is a set of loosely coupled computers (cluster nodes) that collectively provides a single client view of services, system resources, and data. Internally, the cluster uses redundant computers, interconnects, data storage, and network interfaces to provide high availability to cluster-based services and data. Sun Cluster software continuously monitors the health of member nodes and other cluster resources, and uses the internal redundancy to provide near-continuous access to these resources even when failure occurs.

The Java ES installer provides the Sun Cluster Core and the Sun Cluster Agents as separately installable components. Additional Sun Cluster agents are available on separate CDs.
