Server cluster components

Windows Server 2003, Enterprise Edition and Windows Server 2003, Datacenter Edition use the server cluster components to create server clusters that provide high availability, easy manageability, and enhanced scalability. These components work together to manage the cluster objects.

The diagram shows how the cluster components relate to three types of applications and to each other within a single cluster node.

For definitions of these application types, see Cluster application types.

For more information on cluster objects, see Cluster Objects.
