Overview
Veritas Cluster Server (VCS) can connect multiple independent systems to a management framework to improve availability. Each system (or node) runs its own operating system and collaborates at the software level to form a cluster. The VCS combines common hardware with intelligent software to provide failover and control for applications. If a node or a monitored application becomes faulty, other nodes perform predefined operations to take over services and start these services in other locations in the cluster.
