Mike Manos, Microsoft Data Center Chief, has unveiled in his blog the design of future “Generation 4” Microsoft data centers. With the mission to provide massive easy-to-scale computing infrastructure to power the Cloud, Microsoft envisions pre-assembled containers equipped with a few thousands of servers each and its associated cabling and cooling system.
Microsoft is already using the flexibility of “containerized servers” in their Generation 3 Data Center under construction in Chicago. Generation 4 pretends to take the concept of building block even further with a central spine infrastructure for mechanical, electrical and security components, to which the pre-assembled containers are connected in a plug-and-play mode. The containers are designed for high efficiency, minimizing both footprint and the use of water or air for cooling.
The target is to achieve an average power usage effectiveness (PUE)* of 1.125 by 2012. Taking into account that current average data centers have a PUE of almost 2, that would be a huge achievement in green IT, even though Google alreadly claims to be at a 1.21 PUE in some of their facilities.
Microsoft modular container-based design is ideal for a scalable cloud infrastructure that can adapt computing capacity to demand. On top of that, not only operation costs are reduced due to the optimized footprint and cooling, but also CAPEX is improved with server containers assembled in a single manufacturing plant for far less cost than deploying the servers on-site.
Watch Microsoft video illustrating the Generation 4 Data Centers. An interesting approach to counter attack Google’s thought leadership earned with their patent filing for floating, wave-powered data centers.
Microsoft is taking Cloud computing seriously, as Allan Leinwand of GigaOm writes today:
*Definition of PUE extracted from Google corporate site:
PUE is defined as the ratio of the total power consumed by a data center to the power consumed by the IT equipment that populate the facility:
For example, a PUE of 2.0 indicates that for every watt of IT power, an additional watt is consumed to cool and distribute power to the IT equipment.
