The SIOS Protection Suite heartbeat interval is the number of seconds between heartbeat signals that verify the servers are alive. The default (and recommended) interval is six seconds.
If you wish to set the interval at the minimum allowed value of four seconds, then you should ensure that the communication path is configured on a private network and tested thoroughly since values lower than five seconds create a risk of false failovers due to network interruptions.
The heartbeat interval works in conjunction with the maximum heartbeat misses, which has a default value of five (recommended). Setting the maximum heartbeat misses to a lower number (3 or 4) can create a risk of false failovers. Be sure to test thoroughly in your environment.
Setting these values too high can effectively disable SIOS Protection Suite's ability to detect a failure.
