If no specific action to improve the energy efficiency is taken, electricity consumption of data centres is expected to rise to 104TWh a year by 2020. Furthermore, CO2 emissions from the IT-sector, estimated to be 2% of total global CO2 emissions, equivalent to that of the airline industry, would increase significantly.
The EU Code of Conduct for Data Centres launched today by the European Commission provides guidelines, recommendations and best practices, which could lead to a reduction in energy consumption of data centres of up to 20%. This work is in line with the 2020 energy saving targets making an important contribution within the ICT sector.
The key aim of the Code of Conduct is "to inform and stimulate Data Centre operators to reduce energy consumption in a cost-effective manner without hampering the critical function of the facility". This is achieved through a series of best practice recommendations which focus on design in areas such as software, IT architecture and infrastructure. Industry has responded extremely positively to the code, and a number of operators have already started to implement many of the best practices from earlier drafts of the code of conduct.
The European Commission's Joint Research Centre, is a provider of scientific-technical support to EU policy making and as such has initiated this and other codes of conducts in the energy efficiency area . Developed over the last two years, reviewed and refined by a wealth of stakeholders including industry experts from both data centre owners and operators, as well as equipment vendors and Member State experts, the code has become regarded as “the source of information to run an energy efficient Data Centre”.Best practices
o IT equipment: This includes efficient servers and virtualisation: instead of having many servers running at low utilisation, virtual servers are created inside a few servers, thus allowing the server to run at full load, which is more efficient and can result in other servers being switched off.
o Environmental conditions: Servers dissipate a significant amount of heat. Currently server rooms are cooled to low temperatures (e.g. 22°C). This strict temperature regime is not necessary as server rooms can operate at 30° and higher degrees of humidity, therefore eliminating the need to “overcool” Data Centres.
o Efficient management of environmental conditions: air conditioning and air management is one of the key energy demands. Poorly designed Data Centres mix cold and hot air (as in a normal office), but best practice is to keep them well separated, and to provide cooling exactly where it is needed on the server CPUs. In addition to the extended temperature ranges, Data Centres could run on natural cooling as opposed to cold air produced by chillers.

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event
On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.
