      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.

      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 🙂

                      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.

                                        We have a mini split in our on-site DC. It has gone out 4 times in 8 years and been replaced fully once.

                                        At this point in time I have a hard time trusting them.

                                          This looks more like an RV style AC vent than a commercial install.

                                            That's like saying your server died so you don't trust servers. Don't mix one model or vendor being unreliable, and especially not one specific unit and probably an individual installer, with a category of things. If you look at a Pinto, cars seem unreliable. If you look at a BMW 750i, they seem to never break. It's not that they are "cars" that defines their reliability but the maker, model, instance and maintenance on them.
