SonicWall Stateful High Availability Upgrade 1 license(s) License

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.

 

• Improved reliability - By synchronizing most critical network connection information, Stateful High Availability prevents down time and dropped connections in case of appliance failure
• Faster failover performance - By maintaining continuous synchronization between the Primary and Backup appliances, Stateful High Availability enables the Backup appliance to take over in case of a failure with virtually no down time or loss of network connections
• Minimal impact on CPU performance - Typically less than 1% usage
• Minimal impact on bandwidth - Transmission of synchronization data is throttled so as not interfere with other data
