Failover clusters with an even number of nodes usually use a quorum configuration that includes a "witness disk" or "witness file share." In a cluster with an even number of nodes and a quorum configuration that includes a witness, when the witness remains online, the cluster can continue sustain failures of half the nodes. If the witness goes offline, the same cluster can sustain failures of half the nodes minus one.
