Product Description

HP ServiceGuard Quorum Server is an alternate form of cluster lock that uses a server program running on a separate system for tie-breaking rather than a lock disk. Should two equal sized groups of nodes (exactly 50% of the cluster in each group) become separated from each other, the quorum server allows one group to achieve quorum and form the cluster, while the other group is denied quorum and cannot start a cluster.
