An A/C Case Study: Greening the Cork Internet Exchange
Published 09:11, 09 December 07
Tom Raftery is a social media rock star and all-round good egg. This blog provides a really nice in-depth look at the cooling strategies used by the Cork Internet Exchange, a project he has been closely involved in.
Normally GreenMonk echews hardcore green data center stuff, but this one caught my eye because it was driven by CIX, rather than by a big vendor agenda. There is plenty of good information and data in there if you're thinking about cooling strategies. Air-conditioning is one of the major costs in a data center yet its sometimes ignored in favour of trying to make servers cooler. Get the air-con right though and you can cut costs and carbon too.
Its also a great grassroots story because it takes account of the fact its often fecking cold in Ireland. Why spend money on cooling if its cold outside? The basic strategy:
- Utilise free cooling.
- Maximise chilled water temperature.
- Eliminate water mixing.
- Eliminate air mixing.
- Utilise low resistance slow speed air paths.
- Minimise humidification.
