Building a green data centre

Thursday, January 8th, 2009

Here’s an interesting post from Tom Raftery at GreenMonk with practical tips about building an energy-efficient data centre:

One of the low hanging fruit in our DC design was going for cold aisle containment. This simply involves sealing the cold aisle (roof, doors and blanking panels) … this stops air mixing and avoids the warm air from the servers heating the cold air you have just spent a fortune cooling.

….

Source super efficient UPS’ … these UPS’ operate at up to 98.4% efficiency. That is a massive improvement over traditional UPS’ which were typically only around 75% efficient.

….

Typical data centers operate at 19-21C (66.2-69.8F) but in conversations I have had in recent months with HP, Sun, Dell and IBM all have said their equipment will operate no problem in data centers at temperatures of 25C (77F)…

EDUCAUSE resources in Sustainable IT

Tuesday, January 6th, 2009

EDUCAUSE, an American association that promotes the intelligent use of ICT in higher education and of which we are an international member, has published useful information relating to sustainable and “green” IT practice in universities in the USA.

Visit EDUCAUSE’s Sustainable Campus and Green Computing pages for an overview of what’s available and consider joining the Sustainable IT Group listserv. Of value is a number of downloadable presentations from the EDUCAUSE 2008 conference published as How to go green: sustainable computing in Higher Ed.
