Veritas Cluster Server (VCS) by Symantec provides virtual machine monitoring and failover to another host in the Red Hat Enterprise Virtualization (RHEV) environment. VCS enables the following for RHEV hosts:
Connects multiple, independent systems into a management framework for increased availability.
Enables nodes to cooperate at the software level to form a cluster.
Links commodity hardware with intelligent software to provide application failover and control.
Enables other nodes to take predefined actions when a monitored application fails, for instance to take over and bring up applications elsewhere in the cluster.
