I have never actually tried to program against something which talks to multiple DB's, the quickest way would be in your DB connection code to have something that will either:
A. Try the first DB and connect to the second if it's down. B. Randomly choose a SQL server. The most "fluid" solution I could think of would be an application gateway of some sort which will load balance properly to different IP's while in your code you only point to one.
