quorum

(n.) A mechanism to ensure that only one set of cluster nodes is active at any one time and that the configuration data is the most recent. Sun^TM Cluster assigns a quorum vote to each node and to each associated quorum device. If the cluster becomes partitioned, the set of nodes that has more than half of the total number of these quorum votes constitutes the new cluster. The quorum mechanism prevents the split-brain condition and the amnesia condition from occurring.

quorum device

(n.) A device that contributes a quorum vote to a set of cluster nodes with which it is associated.
