      Intel and IBM tests in similar weather conditions (New Mexico instead of Qatar) years ago put optimum efficiency of the datacenter closer to 30-32.

      Wow, that's 86-90F. That seems very warm!

      We studied that project in grad school. It was pretty cool how they set it up. As long as humidity didn't get too high you could have ambient temperatures of ~100F before things started to fail.

      I guess that makes sense. I mean, as a mostly-human being, Syracuse during the summer is often infinitely harder to handle than Dallas ever was due to how humidity affects perception of temperature. I guess it wouldn't be THAT different to electronics.

      Although it is opposite, for electronics which are air cooled, high humidity increases cooling potential. For humans which are evaporation cooled, humidity decreases cooling potential.

        IBM has shown that running at 37C consistently is far better for your gear than bouncing around between 15C and 20C.

          Moving to SSDs actually makes it:

          • Easier to cool as there is less heat generated and less power drawn.
          • Temps can be higher than before.
          • Fluctuations are not as big of a risk.

          You can potentially save a lot of money with SSD for various reasons.

            Fair enough...still, water on a board due to condensation is a risk.

              Oh yes, you can't let there be water, ever.

                    You know it is an enterprise HVAC system when you have a remote 🙂

                      lol, it is not the TV remote controller, i'm talking about the AC

                            I live in the third world too, all remote controlled AC here, too. In the US, that's unheard of (at least to me.)

                                    Most other countries make more use of using Mini-split HVAC units. Here in the US Central HVAC is more common even if it uses more energy (and you have to heat/cool everything instead of just certain rooms like you can with mini-splits, and no duct to lose the temperature in a mini split)

                                      You can get more standard vent looking mini-splits but they aren't as common

                                        Yup. It actually works amazingly well down here where the heat never stops.

                                          It's definitely seen those too, but you are right, it is rare.

                                            We had two of those at a previous job. They worked amazingly well on warm-hot days... didn't work at all during the winter, never figured out why.
