The easiest way to make that happen is to use a product called DRBDI say easy, but the initial setup will be fairly hard as you will need to link all the things you want to fail over into a partition that you can then MIRROR to another machine (if you use drbd).
Here is drbd info: http://www.drbd.org/ http://www.drbd.org/users-guide/index.html Thanks, Johnny Hughes
