A value of 0 indicates that the instance should terminate upon the first quorum heartbeat failure.
Tuning this to a lower number causes an instance to fail over more quickly when access to the quorum device is lost, potentially improving application recovery times. Tuning this to a higher number degrades application recovery, reducing the chances that a transient disk access problem causes an instance failure.
