About Active/Standby HA
HA allows two identical Security Appliances running SonicOS to be configured to provide a reliable, continuous connection to their connected networks. One Security Appliance is configured as the Active unit, and an identical Security Appliance is configured as the Standby unit. In the event of the failure of the Active Security Appliance, the Standby Security Appliance takes over to secure a reliable connection between the connected networks. Two Security Appliances configured in this way are also known as a High Availability Pair (HA Pair).
