Google Motherboard Design Could Get 93% Efficiency

Google is well known for its intensity around data center efficiency. However, what isn't well known are all the ins and outs of how it gets everything running so effectively. It seems, though, that a little information has come out that gives us insight into a specially designed motherboard that is a key ingredient to an excellent PUE.
Google has not disclosed details of its motherboard design, but it did release a white paper calling for designs built on 12V-only power supplies. Besides such supplies, Google's design is said to use at least two full servers per board and remove many of the unneeded parts found in many mainstream server motherboards in an effort to shave cost, reduce power consumption and increase reliability
The secrecy won't last long, since other data centers and manufacturers are moving rapidly towards efficiency. Rackable Systems expects to ship out similar motherboards soon, and other companies will utilize the technology.
"We have way too many voltages generated by power supplies, so motherboard designs get backed into a corner where you get lots of weird power distributions that are very inefficient," [Philip Pokorny, chief hardware architect for Penguin Computing] said, suggesting the 12V-only supplies might hit efficiency levels of 93 percent or higher.
That's a pretty significant efficiency level. Data center efficiency will certainly be a big topic of discussion and news-worthy improvements in 2009.
