Green data centre

You just sent an on-prem app to the cloud and your data centre has empty racks. What now?

On-premises data centres are expensive to build and operate, which is one reason public cloud is so attractive … albeit not so attractive that organisations will immediately evacuate on-premises data centres. But it is generally accepted that lots of workloads will migrate to the cloud in coming years and that hybrid clouds …

The data centre design that lets you cool down – and save electrons

I started my commercial data centre experience in London in the late 1990s. Even back then, most of the service providers were parroting the same mantra: “Your power provision is limited, and we'll charge you through the nose for anything over the basic consumption figure you've signed up to.” The logic most of them gave was …

Green your data centre – without ending up in the Job Centre

Going Green: Tactics (Part 2) Data centres are big, noisy places that seem to have an emphasis on generating heat and making lots of bright lights flash. The first time you visit one, you'd be forgiven for thinking that the service provider's emphasis was on anything but the green credentials. And of course you'd occasionally be quite right: there are DCs …

Bored with Blighty? Relocation lessons for the data centre jetset

Building a data centre in the UK is a difficult business: the land’s expensive, planning permission is tough and the operating costs are high, particularly where power is concerned. As an epicentre of business and commerce, London is the obvious choice – it hosts the country’s major internet transit hub to boot – but it scores …

Cool technology: Submerged blade servers escape the heat

Keeping servers cool is a challenge, even in a purpose-built data centre. Imagine for a moment the difficulty of doing so as part of an oil pipeline in the Australian outback, or as part of a military command post in the deserts of Afghanistan. I can tell you from experience that cooling is a serious issue even during a …

Supercomputer water-cooling comes to solar power

Solar power outfit Airlight Energy has borrowed technology from the world of supercomputers to make its large-scale photovoltaic collectors more efficient, on the way heating water to get a second source of energy. As explained by the IEEE, the Swiss company has created a spin-off called Dsolar to develop its dish-style large- …

Magnetic slurry could deliver heatsink-as-a-service

Serious water-cooled gamer-rig types will probably get busy experimenting with iron filings, water and magnets, to see if they can maker-reproduce research that uses magnets to create what amounts to a switch-on, switch-off heatsink. In a paper co-authored by researchers from MIT and Australia's University of Newcastle, the …

Fukushima switchboard defeated by rat

A careless rat is being blamed for a power outage that left the Fukushima nuclear plant's storage tanks without cooling. Late on Monday, March 18, TEPCO experienced a power cut at cooling equipment serving the nuclear fuel storage tanks, in an incident that took 30 hours to overcome (the company emphaised that during the …

Apple seeks cooling fan patent for iPhone, iPad

A future iPad – or even iPhone – might have a cooling fan inside, if a just-published patent application ever makes it off the drawing board and into an iOS device. The application, "Cooling System for Mobile Electronic Devices", was published on Thursday by the US Patent and Trademark Office, and describes the combination of …

HP's ProLiant Gen8 control freakery

Look out system administrators: Hewlett-Packard wants to give you more time to play video games or polish up your resumes – or both – with the forthcoming launch of its ProLiant Gen8 servers. . As part of its annual shindig with partners and resellers, which was hosted in Las Vegas a week ago, the biggest server shipper in the …

Heat sink breakthrough threatens ventblockers

A US government lab has opened for licensing a novel way of improving the cooling technology used in everything from CPU and GPU coolers to air-conditioning units: make the fan the heat sink, and the heat sink the fan. "We describe breakthrough results obtained in a feasibility study of a fundamentally new architecture for air …

Down and dirty in a monster data centre

Cloud At 66,000 servers worldwide and counting, it’s hard to remember that 10 years ago Rackspace didn’t exist. Now its customers in its Slough data centre alone include the Ministry of Defence and Lloyds TSB. Use an Oyster card, or buy insurance from, and your data is stored on one of the 16,000 Rackspace servers in the …

Data centres gripped by power struggle

Cloud Data centre efficiency is a constant struggle. Choosing the right system for your required tasks is one challenge. Upgrade cycles cause power and heat issues. Existing techniques are continually refined. Combined with emerging technologies, optimal efficiency is a moving target. Space constraints are where the challenges of …

Miracle mono-molecule material could quench hot chips

Boffins working in California say that in five years' time chips and elctronics may be designed with special heat-extracting layers composed of an unusual form of carbon, so reducing the hot-thighs syndrome becoming more and more prevalent among modern laptop users. The material in question is graphene, a sheet of carbon just …

SC09: Mineral oil computing - The coming wave?

OK, sure: liquid can hold and transfer way, way more heat than air – we all know that. But is dropping an entire rack of servers into what looks like an enormous deep fryer the right solution? The answer from the folks at Green Revolution Cooling is a resounding, “Yes!” They claim that using their mineral oil submersion …
