I would consult the specifications for the particular server(s) being used. But I doubt they will differentiate between "server room temperature" and "server rack temperature". Most racks are very open, the idea being that the air available to the racked equipment is essentially the same as the room air.Equipment manufacturers will usually just specify a single ambient temperature, which is assumed to be the temperature of the air being drawn into the equipment.Not sure what you are trying to accomplish, but most modern equipment made in the last decade or two has built-in temperature sensors which are read by various management software that can automatically raise an alert if something is running hot.
Thanks for the information sir. This helps me a lot.In our school the server rack are close but not all. Do you have any idea about the temperature range?
