We've got a small server room ( approximately 600 square feet in area ), and three partially-filled racks of servers, switches, et cetera.
What's the best-practice way of computing the AC capacity needed to hold temperature/humidity conditions constant in a server environment? Our current AC unit was installed about 10 years and 12 servers ago, and despite regular visits from the helpful physical facilities staff-- it's unable to hold temp/humidity without overheating the compressor.
Right now, I've got the estimated power-draw of the servers, switches, etc--- but I can't find a good way to take that power usage and determine cooling needs from that. Any help/directions would be appreciated.
