Network requirement for heartbeat network

What is the recommendation for the heartbeat network ? Does it has to be 10Gig network?
Does the data also transfer through this heartbeat network ?


There is no such thing as

Heartbeat traffic uses the same network as your requests.

ok thanks, is it best practice to use faster network like 10gig for performance benefits ? The database size at some point will be close to 20 TB.

Faster is always better. But speed is only one of many factors. I recommend you take M201 after.

Thanks again !
