SonicOS/X 7 High Availability

Benefits of Stateful Synchronization

  • Improved reliability - By synchronizing most critical network connection information, Stateful Synchronization prevents down time and dropped connections in case of Security Appliance failure.
  • Faster failover performance - By maintaining continuous synchronization between the Primary and Secondary Security Appliances, Stateful Synchronization enables the Secondary Security 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.
