01-SSC-0494 – STATEFUL HA UPGRADE FOR TZ500 SERIES-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.
