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.

Claims

1. A method in a data processing system for a common cluster model for configuring, managing, and operating a plurality of different vendor specific clustering technologies in a data center, the method comprising:

defining a set of cluster domain operations and a set of cluster resource operations for a common cluster model interface of the common cluster model, wherein the set of cluster domain and resource operations operate on the plurality of different vendor specific clustering technologies;

associating a cluster resource with a first cluster domain including a cluster node and with a resource group with a set of resource group properties, wherein the first cluster domain uses a first vendor specific clustering technology;

populating a property of one of the first cluster domain and the cluster resource with vendor specific attributes of the first vendor specific clustering technology using a respective set of cluster domain operations and a respective set of cluster resource operations, wherein the respective set of cluster domain operations operates on the first cluster domain and the cluster node, and wherein the respective set of cluster resource operations operates on the cluster resource and the property; and

associating individual and device driver workflows with one of the first cluster domain, the cluster resource, and the resource group, wherein the individual and device driver workflows interact with the different vendor specific clustering technologies.

2. 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 cluster node is one of a server and a software instance.

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

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

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

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

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

9. The method of claim 1, wherein the set of cluster domain operations includes a start operation, a stop operation, an add node operation, a remove node operation, a start node operation, a stop node operation, a create resource operation, a create resource group operation, an update domain status operation, and an update node status operation.

10. The method of claim 1, wherein the set of cluster resource operations include a start operation, a stop operation, an add group member operation, a create dependency operation, an update operation, and a remove resource operation.

11. A method in a data processing system for a common cluster model for configuring, managing, and operating a plurality of different vendor specific clustering technologies in a data center, the method comprising:
