This wizard guides you through configuration of the quorum for a failover cluster. The quorum configuration determines the point at which too many failures of certain cluster elements will stop the cluster from running. The relevant cluster elements are the nodes and, in some quorum configurations, a witness disk (which contains a copy of the cluster configuration) or witness file share. A majority of these elements must remain online and in communication, or the cluster "loses quorum" and must stop running.  Note that full function of a cluster depends not just on quorum, but on the capacity of each node to support the services and applications that fail over to that node. For example, a cluster that has five nodes could still have quorum after two nodes fail, but each remaining cluster node would continue serving clients only if it had enough capacity to support the services and applications that failed over to it.    Important: Run this wizard only if you have determined that you need to change the quorum configuration for your cluster. When you create a cluster, the cluster software automatically chooses the quorum configuration that will provide the highest availability for your cluster.  To continue, click Next.
