- With High Availability (HA), you can set up two identical SonicWALL devices with SonicOS for a reliable, uninterrupted connection. One SonicWALL device is configured as the primary device and an identical SonicWALL device is configured as the secondary device. If the primary SonicWALL fails, the secondary SonicWALL takes care of providing a reliable connection between the secure network and the Internet. Two devices configured in this way act as a high-availability pair.
- Good but not great
