This section shows examples of quorum configurations that are recommended. For examples of quorum configurations you should avoid, see Bad Quorum Configurations.
Two quorum votes are required for a two-node cluster to form. These two votes can derive from the two cluster nodes, or from just one node and a quorum device.
You can configure a greater than two-node cluster without a quorum device. However, if you do so, you cannot start the cluster without a majority of nodes in the cluster.
