Couldn't help adding some "dealing with cold" stories to this thread. Being in Montana you learn something about cold. 1) The state had a computer installation in the basement of the national guard armory. The COOLING system died a few years back and they had to shut down the operation for something like 2-3 days (not sure the exact duration) while they got someone in to fix it. The funny part: This occured the same week as our winter "cold week" which generally has a HIGH of about -10F. Yes, thats 10 degreees BELOW zero. You'd think they could have figured some way to get some OUTSIDE air in so they could turn the thing back on. 2) We cool our (ISP) installation during the summer with building AC (Small installation, not many btu's). The problem occurs during the Winter when they turn off the AC and the heat on and the BTU's generated in the room added to the heat causes a heat problem. We fixed this a few years back by adding a fan which brings in fresh air from outside. I'm not sure what we were thinking but we initially DIDN'T have a thermostat on it - it ran all the time. I decided it was time to add one when I came in one day and the computer room was cold enough I could see my breath in the room (close to if not freezing). 3) Not exactly related but quite a few years ago I was doing some work for a radio station in Central Utah. They had a mountaintop transmitter site (10,000 ft or so). We had to specially design the cooling system for the transmitter to increase airflow past the transmitting tubes, etc. because the air was so thin. At 10,000 feet the same "High CFM" fans which work wonders at 5,000 feet just don't move enough air through the stuff. -forrestc@imach.com On Sat, 18 Sep 1999, Deepak Jain wrote:
Joke - Forgot the smiley face. Picture a room with open windows at the top of a mountain. You just need wall fans.
I don't want to know the cost of lighting up a mountain top.

If the next is exchange is located in a cold enough location (naturally) we don't even have to worry about HVAC redundancy.
Uh, why? I have built many datacenters, you need redundancy in your HVAC systems even if it is 30^ outside.
