Abstract
A method and system for distributing various types of cluster data among various storage devices of a server cluster. Cluster core boot data that is needed to get the cluster up and running is stored on a quorum storage mechanism, separate from cluster configuration data which is stored on lower cost and/or higher performance storage. The quorum storage may be implemented via a quorum of nodes, a single quorum disk or a quorum of replica members. The state of the cluster configuration data, as well as the state of other cluster data, may be stored on the quorum storage, thereby assuring the integrity of the data while providing increased reliability through the use of mirror sets of storage elements or the like for storing that data. Significant flexibility in how a cluster may be configured is achieved, along with improved cluster performance and scalability.
