Please see the following list for definitions of clustering terms used in the CA SRM documentation.
The virtual entity that represents the two cluster nodes, which are working together as a single resource. The cluster functions as though it were a physical machine, with its own name and IP address, but is in fact only a representation of such an object.
When we refer to "the cluster" in the documentation, this is the object we are referring to.
A physical computer system which has the Microsoft Cluster Service (MSCS) installed, and which belongs to a cluster.
A set of resources, which may be dependent upon one another, defined and managed via MSCS. No resource can belong to more than one group, and a group can only belong to one node at any given time. For failover purposes, all resources in a group are treated as a single entity and failed over together.
For example, you might define a Web Server group that consists of the following resources:
A group which contains a unique network name and an IP address, and therefore is accessible as though it were a physical server.
Note: Do not confuse clustered virtual servers with servers managed by virtualization software, such as VMware or Microsoft Virtual Server.
