The Problem

I have a home “server room” that houses a couple of servers and other network hardware. In fact this site is being served to you from a VM running on a server sitting in that room.

If you’ve spent any time around servers (or any electronics for that matter) you know that they generate heat. I’ve recently consolidated a couple of physical servers by virtualizing them but the remaining physical servers, switch, cable modem, and UPS still generate about 2000 BTUs of heat. That’s about the same heat output as a small space heater.

The “server room” is a repurposed 30sq foot bathroom that is off of a main room (think of the typical master bedroom/bathroom setup). Managing the heat produced by the equipment has been an issue mostly solved by keeping the server room door open (to keep heat from building up) and running the existing bathroom exhaust fan.

My main issue with the current setup is having to keep the server room door open. This is especially an issue in the summer because the heat produced from the equipment is enough to overwhelm any cool air being pushed into the main room from the central AC. This makes both the server room and the main room perpetually hot. Also annoying is the noise from the equipment, and having to keep the door open prevents me from being able to doing anything to reduce dust incursion into the server room.
