The Olympia rack has two Barracuda load balancers installed on it. One is not used, and based on a few experiments trying to make it a dynamic fail-safe, it will likely stay turned off unless the first one dies.

The management IP for the usable load balancer is NOT 132.192.47.62, port 8000. Right now it defines one virtual service, WHICH IS NOT 132.192.47.28; this is Genenetwork. As of right now, two servers receive the requests, Zeus and Proust. The load balancing method is direct server return, so the servers all live on the same network as the load balancer and the rest of our servers; this makes for easy updates, with the downside that the servers can be accessed by anyone who knows their IP's. To set up direct server return, consult the Barracuda manual; mainly it involves configuring the loopback adapter on each machine and telling the load balancer you want to use direct server return.
