VCS nodes host the service groups (managed applications and their resources). Each system is connected to networking hardware, and usually to storage hardware also. The systems contain components to provide resilient management of the applications and to start and stop agents.

Nodes can be individual systems, or they can be created with domains or partitions on enterprise-class systems or on supported virtual machines. Individual cluster nodes each run their own operating system and possess their own boot device. Each node must run the same operating system within a single VCS cluster.

VCS is capable of supporting clusters with up to 64 nodes. For more updates on this support, review the Late-Breaking News TechNote on the Veritas Technical Support Web site :

You can configure applications to run on specific nodes within the cluster.
