High Availability (HA) allows two identical SonicWALL appliances running SonicOS to be configured to provide a reliable, continuous connection. One SonicWALL device is configured as the Primary unit, and an identical SonicWALL device is configured as the Secondary unit. If the Primary SonicWALL fails, the Secondary SonicWALL takes over to secure a reliable connection between the protected network and the Internet. Two appliances configured in this way function as a High Availability Pair.
Converts HA unit to the basic standalone appliance without services
High Availability allows two identical SonicWall security appliances running SonicOS Enhanced to be configured to provide a reliable, continuous connection to the public Internet.
One SonicWall device is configured as the Primary unit, and an identical SonicWall device is configured as the Backup unit. In the event of the failure of the Primary SonicWall, the Backup SonicWall takes over to secure a reliable connection between the protected network and the Internet. Two appliances configured in this way are also known as a High Availability Pair (HA Pair).
High Availability provides a way to share SonicWall licenses between two SonicWall security appliances when one is acting as a high availability system for the other. To use this feature, you must register the SonicWall appliances on MySonicWall as Associated Products. Both appliances must be the same SonicWall model.
