Would it be possible to keep TCP sessions when primary LB-8000 crashes? How about persistence information?

LB-8000 supports stateful failover.
All the TCP connections and persistence information are synchronized with each other in real-time basis.
Therefore, if primary LB-8000 crashes and backup LB-8000 takes over, you will not lose any TCP connections and persistence records.
For example, if a client is downloading a file through FTP and the primary LB-8000 crashes, the download will still be able to proceed without interruption.
In addition, the stateful failover is bi-directional. Therefore, even if the backup LB-8000 is active, after primary recovers, the TCP connections and persistence records can still be safely transferred back to the primary.
