Nouveau datacenter Microsoft a Dublin, PUE de 1.25
Microsoft a annoncé le 23 Septembre 2009 l’ouverture du datacenter de Bublien (Ireland) pour héberger les sevices Windows Azure (Cloud Computing) et les services Live (Hotmail, Skydrive…)
Le PUE de cet ensemble innovant est de 1.25 grâce aux technologies de “free-cooling” utilisant une ingénieurie du bâtiment pour refroidir le datacenter grâce à des courants d’air

Morceaux choisis:
* Almost exclusive use of 'free-air' cooling for the total facility. By leveraging the ambient temperatures in Ireland and by isolating the extraction of heat generated by the IT systems, the data centre environment can be maintained at operating temperatures without the use of mechanical / refridgerated cooling systems for over 95% of the time. Mechanical cooling systems will only be employed during periods of extreme temperatues or where there are external contaniments in the air such as smoke or dust. Mechanical cooling typically represents ~38% of the power consumed in traditional data centres.
* By leveraging the 'free-air' cooling and hot aisle isolation model described above, Microsoft has been able to avoid the use of chilled water cooling systems. Traditional data centres of this scale use ~18 million litres of water each month to assist with the cooling systems.
* The vast majority of servers deployed in this new data centre are the latest generation of systems, designed through tight collaboration between Microsoft and the hardware manufacturers to deliver the highest performance with the lowest levels of power consumption and heat generation. These systems are shipped to the data centre preinstalled into the server racks, resulting is subtantial reductions in transportation and packaging overheads.
* The IT systems (servers, storage, networking) are constantly monitored for utilization and power consumption and data gathered through this instrumentation is aggregated to provide the business with visibility to the efficiency of their systems as well as the carbon generation. All stakeholder teams from application developers to data centre operations are incented to drive for continuous improvement of operational efficiency.
