During a vSphere vMotion operation, memory pages are copied from the source ESXi host to the destination. These pages are copied while the virtual machine is running. During the transition of the virtual machine from running on the source to the destination host, a very slight disruption in network connectivity might occur, typically characterized by a single dropped ping. In most cases this is not a concern, however in highly active environments, this disruption might be enough to trigger the cluster toevict the DAG node temporarily, causing database failover. To mitigate cluster node eviction, the cluster heartbeat interval can be adjusted.
My Question is how should we configure heartbeat interval, and what should be the idle value. Kindly suggest. Many Thanks.
