Your weakest link is not having redundant power feeds. Two PSUs doesn't help much when they both draw power from the same place :-) Second is inadequate cooling in the data centre 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. Then there is is drive failure - it's the hardest working component. SSDs less so, but they still draw considerable power and get hot Everything else is a distant concern. When did you last hear of a CPU failure anywhere at any time? CPUs do not fail for the most part. When they do it's because everything else got hot which brings us back to #2 in the list. -- Alan McKinnon alan.mckin...@gmail.com
