    70 to 72 degree with a RH 45 to 50%. Keep those dry bulb temps. Remember, humidity is relative to the temperature you are at.

    Speaking of overcooling, there are data center managers who would insist that we keep their rooms in the low 60s (temperature), despite our insistence that the humidity would spike.

    Their heat load was strong and we wrestled with humidity issues.

    Money was no object, except when nickel and diming us would give him something to crow about. After all, he had to justify his existence too.

    You could see your breath when working on the condensate pumps under the floor.

    Anyway, the folks that work in those rooms usually have a cardigan or two hanging on the back of their chairs. And the managers rightly don't give a rip whether or not their peeps are cold or not. Those rooms are not designed for people.
    It's great to be alive and pumping oxygen!

    Ain't that the truth.....only the server racks matter. Everything else, is exspendable.
