Toolserver:Admin:Haproxy

haproxy is a TCP load-balancing daemon; it accepts connections and routes them to an appropriate server. It is used to distribute MySQL connections to an appropriate database.

haproxy runs on the HA cluster in. The cluster resource group and resource are both called. To configure it, edit, then do. Note that at the moment, this will disconnect all MySQL clients; there should be a nicer way to do this soon.
