you have "ha" clusters and "compute" clusters

sounds like an "ha" ( high availability ) setup might help you but its a
little more work than "easy way" to do the same


- compute cluster  -- lot of cpu doing the work of solving a complex
  problem  ( biotech, prime numbers, weather simulations, nuclear
  simulations, etc )


- ha cluster -- if one machine fails, the remaining servers can take
  over and nobody will notice the dead "www" server
 	- you can do the same with a good backup scheme but if a system
	dies, you have to change a backup machine called "www.backup" to
	become the new "www machine" to make it go live after a failure
	( can be good or bad to do things manually .. pov ... )

more cluster fun ( lots o links for apps and howto and different types )
