I can afford a little bit of down time, not too much. My plan was to have a second smaller IBM server handy for redundancy but it really all comes down to cooling and power. This particular setup is becoming unjustifiable to run as it continues to cost us so much in power which is why I'm trying to find a way to cut costs while keeping the setup.
I believe the BladeCenter uses some 600watts simply idling, I'll have to look at how it all breaks down.
Thanks.
