What a great idea. It just so happens that I have arrived at work this morning to find our main file server is not available because our IT guys decided to swap the hardware last night and it didn't go quite according to plan!

I think I'll forward them a copy of your article in the hope they take the hint. The irony is that we have invested in blade servers and shared storage (SAN). We have virtualised everything but not created the servers as single node clusters. After reading your article it seems we might have missed a trick.
