A few weeks ago I got an email notification from my Kaleidescape
movie server saying temperatures has exceeded safe operating range and the server would be shutting itself down if temps didn’t soon return to normal. “What the hell?!” I wondered. Nothing had changed in my rack, I hadn’t added any new gear or changed anything with the ventilation and the server was exactly where it had always been sitting and working fine for the past few years. Of course, I immediately blamed my 7 year old daughter, accusing her of all manner of destructive behavior, but when she assured me she was (in this case) innocent, I searched further.
