At Soft Layer redundant power supplies are actually powered by redundant power feeds. > Second is inadequate cooling in the data centre Easy to monitor though. > Third is idiots in the data centre doing stupid things like activating > the fire suppression or any of the other truly epic fail tricks clueless > customers get up to.

I had one fail a number of years ago but I do think it was because of heat. Plus I think that was in my overcl0cking days. Out of curiosity though, would the system continue if I were to lose a CPU and it didn't fry anything? - Grant
