An independent survey of senior data centre professionals from across Europe carried out on behalf of Digital Realty Trust has revealed heightened concerns about government regulation in the European data centre industry.

hed the new guidelines at its second annual technical forum in San Jose Wednesday. The Green Grid calls it the Data Center 2.0 program, which it says will create a "multi-year set of design guides proposed for use by data center operators and designers to build and operate energy efficient data centers."

The Green Grid, a non-profit consortium dedicated to advancing energy efficiency in data centers and business computing ecosystems, has announced its technology roadmap and key deliverables for 2007. For the next several months, The Green Grid will focus on data collection through the documentation of existing standards and the evaluation of metrics; data assessment through a market study of current efficiency practices; and technology proposals that outline The Green Grid's recommendations for the future of energy efficient data centers.

Corporations are mishandling their data center energy consumption to the point that they risk disruptive failures of their technology infrastructure

By using direct current, rather than drawing electricity from outlets that supply alternating current, data center managers can reduce their energy consumption by up to 40 percent, according to the company.

The paper itself is flawed suggesting that virtualisation can reeduce the number of servers required to 7% - enough to handle the average processing load. Webusers want instant reaction during the peak - for that you need spare capacity. Is this a surprise?

The Internet doesn't produce belching smokestacks or toxin-spewing drainpipes. Instead, the environmental impact of the data centers that power the Web and private networks is about as visible as the electrons moving around a company's servers. But visible or not, the ecological and economic costs of those servers are massive. A report released last week by the Environmental Protection Agency estimated that U.S. data centers (collections of computers used to power businesses' and government agencies' IT infrastructures and Web sites) consumed around 61 billion kilowatt-hours in 2006 at a cost of about $4.5 billion. That's about 1.5% of total U.S. electricity consumption, more than the electricity used by American televisions, or equivalent to the output of about 15 typical power plants

Emerson had originally considered placing condensers separate from the building. Instead, the condensers were installed on the data center roof near the computer room's air conditioning systems, saving about 2.5 miles of copper piping.

That's why a small server-farm company called AISO.net (for "affordable Internet services online") has gone completely off the grid. Located 80 miles southeast of Los Angeles in the desert hamlet of Romoland, AISO.net has flanked its 2,000-square-foot building with two banks of ground-mounted solar panels, which generate 12 kilowatts of electricity. Batteries store the juice for nighttime operation.

UK managed hosting provider Ultraspeed has announced the roll-out of a unique combination of technology designed to deliver a next generation hosting service with dramatically enhanced reliability and a reduction in power consumption estimated at 40%. To achieve this, the company is using an innovative blend of measures which includes the adoption of DC power, a 'diskless' server environment and the latest Intel Xeon 5300 low-voltage quad core processors.

About 63 percent of Indian IT shops have completed a retrofit of existing server rooms to increase energy efficiency, or have a pilot project underway, according to a recent study. It's similar in Brazil, but IT companies there tend to favor building new server rooms before modifying existing ones.
