Failover Performance

Failover performance metrics include failover time and maximum message rates.

• The failover time is 3 seconds in a normal situation. The failure detection time is 1 second, and the error recovery period is 2 seconds. Heartbeat monitoring is done over the TCP/IP protocol using a heartbeat packet of 64 bytes and a latency of 100ms.
• The failover configuration supports the same maximum message rate as a single LogLogic LMI appliance with the same limitations.
  Warning: Make configuration changes only to the active appliance, and not to the standby appliance. To avoid mistakes, always use the cluster’s Virtual IP address to interact with the configuration GUI.
