Abstract
Hyperclusters are a cluster of clusters. Each cluster has associated with it one or more resource groups, and independent node failures within the clusters are handled by platform specific clustering software. The management of coordinated failovers across dependent or independent resources running on heterogeneous platforms is contemplated. A hypercluster manager running on all of the nodes in a cluster communicates with platform specific clustering software regarding any failure conditions, and utilizing a rule-based decision making system, determines actions to take on the node. A plug-in extends exit points definable in non-hypercluster clustering technologies. The failure notification is passed to other affected resource groups in the hypercluster.
