SonicWall Stateful High Availability Upgrade - Lizenz (02-SSC-5889) Brand

Stateful High Availability (SHA) provides dramatically improved failover performance. The Primary and Backup appliances are continuously synchronized so that the Backup can seamlessly assume all network responsibilities if the Primary appliance fails, with no interruptions to existing network connections.Stateful High Availability is not load-balancing. It is an active-idle configuration where the Primary appliance handles all traffic. When Stateful High Availability is enabled, the Primary appliance actively communicates with the Backup to update most network connection information. As the Primary appliance creates and updates network connection information (VPN tunnels, active users, connection cache entries, etc.), it immediately informs the Backup appliance. This ensures that the Backup appliance is always ready to transition to the Active state without dropping any connections.The synchronization traffic is throttled to ensure that it does not interfere with regular network traffi
