Hi Victor

Check out a product from DPT.

The product is called ServerOnCall, Effectively it requires the use of their
raid controllers and the software, but continually checks the "heartbeat" of
all servers on the network and if any one fails a backup server immediately
gets put online with that servers configuration, hard disk data etc.

Too much detail to explain here as to what it does and how, and perhaps it's
a "next step" solution for you rather than solving your immediate problem
(i.e. I think it requires 3 servers), but it is a great system, cheaper
than wolfpack, and definitely worth a look.
