Abstract
A cluster system is treated as a set of resource groups, each resource group including a highly available application and the resources upon which it depends. A resource group may have between 2 and M data processing systems, where M is small relative to the cluster size N of the total cluster. Configuration and status information for the resource group is fully replicated only on those data processing systems which are members of the resource group. In the event of failure of a data processing system within the cluster, only resource groups including the failed data processing system are affected. Each resource group having a quorum of its data processing systems available continues to provide services, allowing many applications within the cluster to continue functioning while the cluster is restored.
