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.
