We use a load balancer in front of our ESAs. Look in the user guide (the advanced one, I think), for "direct server return" load balancing.
Using a load balancer makes for practically instantaneous fail-over. Granted, thats not as big a deal for SMTP as it is for other protocols, but it does avoid unnecessary mail delays. It also allows new ESAs to be deployed without DNS shenanigans, since the MX record refers to the load balancer. That's very helpful when you're protecting several hundred domains like we are. Updating hundreds of MX records is a drag.
