Groups

A group is a collection of cluster resources with the following characteristics:

•All of the resources in the group are moved to the alternate node when one resource in a group fails and it is necessary to move the resource to an alternate node.

•A group is always owned by one node at any point in time, and a resource is always a member of a single group. Therefore, all of a group's resources reside on the same node.

Groups enable resources to be combined into larger logical units. Typically a group is made up of related or dependent resources, such as applications and their associated peripherals and data. However, groups can also be established with resources that are unrelated and nondependent to balance the load or for administrative convenience.

Every group maintains a prioritized list of the nodes that can and should act as its host. The preferred nodes list is generated by the Cluster Service. Cluster Service produces a list of preferred nodes for a group from the list of possible owners that is maintained by the group's resources and can be modified by an Administrator.

To maximize the processing power of a cluster, establish at least as many groups as there are nodes in the cluster.

Cluster Resources

A cluster resource is any physical or logical component that has the following characteristics:

•Can be brought online and taken offline

•Can be managed in a server cluster

•Can be hosted (owned) by only one node at a time

To manage resources, the Cluster Service communicates to a resource Dynamic Link Libraries (DLL) through a Resource Monitor. When the Cluster Service makes a request of a resource, the Resource Monitor calls the appropriate entry-point function in the resource DLL to check and control the resource's state.
