Microsoft's Kevin Timmons, GM, Datacenter services announced that "their most innovative new datacenters is set to open in Quincy, WA in early 2011 and incorporates key learnings from award-winning facilities that Microsoft opened last year in Chicago and Dublin."
"The Dublin facility uses server PODs and outside air economization to cool the servers, which significantly reduces cooling expense and infrastructure costs. We took a slightly different approach with our Chicago datacenter which utilizes water-side economization for cooling and improves scalability by using IT Pre-Assembled Components (ITPACs.)
An ITPAC is a pre-manufactured, fully-assembled module that can be built with a focus on sustainable materials such as steel and aluminum and can house as little as 400 servers and as many as 2,000 servers, significantly increasing flexibility and scalability."
