Submission + - Green Your Server Farm (worldchanging.com)

An anonymous reader writes: Jer Faludi at Worldchanging has put together a terrific overview of the recent advances in creating greener tech for server farms, which — since they make up about 1.5 percent of planetary energy consumption — are a major target for sustainable computing efforts.


It's not just the computers themselves that use all this power: the combined heat output of all these servers, hard drives and network gear is so large that massive air conditioning is required to keep it all from overheating. "Cooling is about 60 percent of the power costs in a data center because of inefficiency," said Hewlett Packard executive Paul Perez in Data Center News. "The way data centers are cooled today is like cutting butter with a chain saw." Cooling capacity is often the limiting factor of how big these systems can be — I've talked with more than one engineer whose data center facility sat half empty or more; even though there was plenty of room for more servers, the building's air conditioning was maxed out.

It's funny.  Laugh.

Submission + - Energy Drinks Linked To Heart Risk (medicalnewstoday.com)

explosivejared writes: "Before any slashdotters here get another urge to "ride the bull" you might want to check this out. A study presented to the American Heart Association has linked popular energy drinks to heart disease and high blood pressure. Once again high levels of caffeine and taurine are being touted as major health risks. This could be a potential blow to the ever health-minded /. community. However, no word yet on what the ill effects of hot pockets, though."

Submission + - Seagate's 1TB Barracuda 7200.11 Drive Tested (hothardware.com)

MojoKid writes: "Seagate was surprisingly late to join the small, but elite club of storage manufacturers shipping one terabyte (1TB) class hard drives. First out of the gate was Hitachi, who made it to market several months beforehand with a high-density five-platter 1TB hard disk design. While Hitachi's performance, thermals, and acoustics have all been tested to be fairly solid, many high-end buyers have been waiting for other manufacturers, namely Western Digital and Seagate, to get into the mix as well. This review shows that, the Seagate Barracuda 7200.11 is one of the most advanced consumer level hard disks on the market. The drive showcases second generation perpendicular recording, 32 MB of cache, excellent multi-tasking performance, very light power consumption and relatively quiet acoustics, not to mention its massive 1 Terabyte capacity."

Monitor Draws Zero Power In Standby 405

fifthace writes "A new range of Fujitsu Siemens monitors don't draw power during standby. The technology uses capacitors and relays to avoid drawing power when no video signal is present. With political parties all over Europe calling for a ban on standby, this small development could end up as one of the most significant advances in recent times. The British Government estimates eight percent of all domestic electricity is consumed by devices in standby."
