      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!

        Why is your server room at 17 anyway? That is far, far below recommended temperatures.

        And if you're dealing with high humidity as it is, this will only amplify the condensation problem by keeping the temperature lower...

        Yup, I'd look at raising that at least to 25.

        the problem is the high temperature we have in qatar, usually 46 - 38 C, so if i raise the temperature, i risk to kill the servers

          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.

            Your server room should have independent air conditioning. Keeping it around 20-25 C should be fine.

              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.

                It sure does, because IT has this cultural obsession with thinking only in terms of the servers themselves and not holistically for the business. It's "IT at any cost" thinking. That and poor airflow forces datacenters to go with super cold air to make up for heated air pockets.

                But servers do not need the cold air that IT generally assumes. That's a myth that just keeps getting repeated. Good airflow and holistic business thinking put the optimum temperatures much higher in cases where the cold air is not essentially free (like Scotland.)

                  What matters is keeping it consistent, not the temp itself.

                    That's NOT how air conditioning works. The temperature outside has nothing to do with the temperature inside. If you set it to 17, it is 17 no matter what the temp is outside. If you set it to 25, it is the same 25 as for any of us. Your 25 is not hotter than ours. What DOES matter is that the cost of cooling from 46 to 17 is much, much higher than cooling from 25 to 17. So the price for going unnecessarily low is more for you.

                      We've done these tests (nonvoluntarily) with HP servers and they ran happily towards 160F!! But I would not recommend it since humans can't go in the room to replace parts.

                          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.

                                            i go to the server room to raise the tempreture, i realize that the remote controller is missing 😲

                                            Look in the couch. It is always in the couch.

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

                                            He is well aware.

                                            i know, and he know that i was joking 😉
