Matthew Garrett - Powering Down
Power management - from laptops to rooms full of servers - is a topic of interest to everyone. In the beginning there was the desktop computer. It ran at a fixed speed and consumed less power than the monitor it was plugged into. Where computers were portable, their sheer size and weight meant that you were more likely to be limited by physical strength than battery life. It was not a great time for power management.

Data centers should not be cooled by air circulation anymore. It is such a waste of energy!! Since micro compressors are in the market I start working with micro heat exchangers (40W/cm2) and place an evaporator into the data centers cooling them down to ambient temperature which allows me to work with 20°C of evaporating temperature, having then a great COP.

In addition to the technical solutions presented here, siting is definitely one of the most important factors that affect the energy consumption and environmental effects of a server farm. There are places with cooler climates than in the continental US and with more green electricity available. I would recommend anybody considering siting a datacenter to take a look at the Finnish website on these issues: http://www.fincloud.freehostingcloud.com/

Interesting and useful article. I wish I could understand why it does not seem to be feasible to use a heat pump to efficiently remove heat from our datacentre and use it to heat water or even space. It seems such a waste to just throw it outside.
