Abstract

A method, apparatus, and computer instructions are provided for a common cluster model for configuring, managing, and operating different clustering technologies in a data center. The common cluster model supports peer cluster domains and management server cluster domains. Each cluster domain may have one or more cluster nodes. For each cluster domains, one or more cluster resources may be defined. These resources may depend on one another and may be grouped into a resource group. A set of cluster domain and cluster resources logical device operations are provided to configure, manage, and operate cluster domains and its associated resources.

defining a first cluster domain for a clustering technology of the plurality of different vendor specific clustering technologies using the common cluster model interface, wherein the first cluster domain includes at least one cluster node;

associating the at least one cluster resource with one of the first cluster domain and the at least one cluster node;

populating at least one property of one of the first cluster domain and the at least one cluster resource with vendor specific attributes of the clustering technology of the plurality of different vendor specific clustering technologies using the set of cluster domain operations and the set of cluster resource operations, wherein the set of cluster domain operations operates on the first cluster domain and the at least one cluster node, and wherein the set of cluster resource operations operates on the at least one cluster resource and the at least one property;

associating the at least one cluster resource with a resource group; and

defining a set of resource group properties for the resource group, wherein the set of cluster resource operations operates on the resource group and the set of resource group properties.

4. The method of claim 1, wherein the first cluster domain is one of a peer cluster domain and a management server cluster domain, and wherein the at least one cluster node is one of a server and a software instance.

5. The method of claim 1, wherein the first cluster domain includes a second cluster domain.

6. The method of claim 1, wherein the first cluster domain and the at least one cluster node includes an observed state and a desired state, wherein the observed state indicates a current state.

7. The method of claim 1, wherein the at least one cluster resource is a type of software resource, and wherein the at least one cluster resource includes a relationship to another cluster resource.

8. The method of claim 1, wherein the at least one cluster resource is aggregated to form a failover cluster resource for a high availability cluster, wherein the failover cluster resource includes redundancy of the at least one cluster resource.

9. The method of claim 1, wherein the resource group includes another resource group, and wherein the resource group depends on the another resource group.

10. The method of claim 1, wherein the at least one cluster resource is located in one of a same data processing system and different data processing systems.
