We have a team, called Microsoft Global Foundation Services, who have the job of building clouds. Or at least, building ‘the Cloud’ – they design, build, run and support our global data centres which are at the hub of all of our cloud services. In Europe, we have one in Ireland and one in Holland. I don’t know about the Amsterdam one, but the Dublin one is roughly three times the size of the main halls at Olympia (imagine – instead of lots of snazzy stands, that space packed full of humming server racks, a bit like our Chicago datacentre on the right). The Dublin one is where we host all of our UK Live@edu email services and data.
Obviously, at the rate we’re building these data centres, and the huge cost involved, there’s a constant journey to work out how to make the data centres increasingly efficient – especially because of their energy usage, which is a huge part of the cost of running a data centre.
Now, some of the lessons we’ve learnt aren’t things you can apply in your college server rooms easily (like cleaning the roof and painting it white, which reduces cooling cost), and playing around with the wall positioning to improve air flow.
However, some of the things that have been learnt could be of use to you, and help you to reduce your carbon emissions and running costs – like making a trade-off in processor performance to achieve the most efficient Performance per Watt per dollar (which is one reflection of the true cost of providing a server service). We’ve also made adjustments to the temperature servers are cooled to – and switching to using more free air cooling to replace air conditioning. And we’ve even experimented by operating servers outside under a tent.
The good news is that as we do this work, we publish it in a consumable format. If you’re interested in how to help reduce your server running costs, or in what we’re doing when we’re building massive data centres, then I can recommend “A Holistic Approach to Energy Efficiency in Datacentres” from the Microsoft Global Foundation Services team.
There is also a lot of detail about different projects going on to look at energy efficient computing, within data centres and elsewhere, on our www.microsoft.com/environment website. Some of the research up there is around Cloud Computing futures, data centre monitoring and optimisation, reducing disk energy consumption, universal parallel computing and power aware developer tools.
And finally, if you’re interest knows no boundaries, then you might be interested in the MS Datacenters blog, which has tells the story of how we’ve grown our data centres around the world over the last few years, and shares some more of the lessons we’ve learnt.
