Serial failover is faster for failover. However, you still need network failover configured for mirroring of session data.

 

 

 

sol2397: Comparison of serial failover and network failover features

Note: Due to faster response time, F5 recommends that you use serial cable failover whenever it is possible to install the serial failover cable between the two BIG-IP systems. The VIPRION system supports only network failover.

 

 

Important: Even with serial cable failover configured, communication over the network is necessary for certain features to function properly, for example, the communication that occurs over the network during failover mirroring.
