Who'd have thought it.. Google runs of thousands of 12-volt batteries :o) Each Google server has its own 12-volt battery to supply power if there's a problem with the main source of electricity. The company also revealed for the first time that since 2005, its data centers have been composed of standard shipping containers--each with 1,160 servers and a power consumption that can reach 250 kilowatts. ... Most people buy computers one at a time, but Google thinks on a very different scale. The cores of the company's data centers are composed of standard 1AAA shipping containers packed with 1,160 servers each, with many containers in each data center.

Google's big surprise: each server has its own 12-volt battery to supply power if there's a problem with the main source of electricity. The company also revealed for the first time that since 2005, its data centers have been composed of standard shipping containers--each with 1,160 servers and a power consumption that can reach 250 kilowatts.

I love the approach and the the fact it's unconventional and better - google servers revealed

それは「月を追いかける（follow the moon）データセンター」というコンセプトです。 夜間は外気温も低く、また電気料金も安くなっています。そこで、世界中のデータセンターのうち、夜になっている地域のデータセンターだけを稼働させれば、低い外気温を活用でき、しかも夜間の安い電気料金を利用できます。これはクラウド技術者のあいだで議論されている構想ですが、グローバルにデータセンターを展開し、その負荷をダイナミックに切り替えられるグーグルであればそれを実現可能かもしれない、とこの記事「Google's Chiller-less Data Center 」では解説されています。

The climate in Belgium will support free cooling almost year-round, according to Google engineers, with temperatures rising above the acceptable range for free cooling about seven days per year on average. The average temperature in Brussels during summer reaches 66 to 71 degrees, while Google maintains its data centers at temperatures above 80 degrees.

Google’s Chiller-less Data Center

最新のデータセンターは冷却設備を持たない

"Google (GOOG) has begun operating a data center in Belgium that has no chillers to support its cooling systems, a strategy that will improve its energy efficiency while making local weather forecasting a larger factor in its data center management. [..]So what happens if the weather gets hot? On those days, Google says it will turn off equipment as needed in Belgium and shift computing load to other data centers. This approach is made possible by the scope of the company’s global network of data centers, which provide the ability to shift an entire data center’s workload to other facilities. [..]The ability to seamlessly shift workloads between data centers also creates intriguing long-term energy management possibilities, including a “follow the moon” strategy which takes advantage of lower costs for power and cooling during overnight hours. In this scenario, virtualized workloads are shifted across data centers in different time zones to capture savings from off-peak utility rates."

Very Cool. I want this!

Underneath Stockholm, deep in the bedrock exists a data center better than any high tech lair Hollywood could probably dream up. Bahnhof, one of Sweden's largest ISP's has created a bunker of high tech goodness that is surely to astound.

these people need to start doing centers and offices in the U.S....

Salesforce - incredible efficiency! and other metrics

all of Salesforce.com runs on only about 1,000 servers. And that is mirrored, so it is really only 500
