Scenario B: Stateful HA Pair
For network installations with two Dell SonicWALL
SuperMassive 9200 appliances configured as a stateful
synchronized pair for redundant High Availability (HA)
networking.
In this scenario, one SuperMassive 9200 operates as the
Primary gateway device and the other SuperMassive 9200 is in
Idle mode. All network connection information is synchronized
between the two devices so that the Secondary appliance can
seamlessly switch to Active mode without dropping connections
if the Primary device loses connectivity.
To set up this scenario, follow the steps covered in:
• Configuring a Stateful HA Pair, page 37
