File share witness
The file share witness feature is an improvement to the current Majority Node Set (MNS) quorum model. This feature lets you use a file share that is external to the cluster as an additional "vote" to determine the status of the cluster in a two-node MNS quorum cluster deployment.
Configurable cluster heartbeats
The configurable cluster heartbeats feature enables you to configure cluster heartbeat parameters. This may help avoid unnecessary cluster failovers. These failovers occur because of a temporary network problem that may cause packets to be dropped or delayed. The configurable cluster heartbeats feature may help in an environment where cluster nodes are geographically dispersed.
