The first DDR5 RAM modules promise faster, more efficient PCs
Korean chip manufacturer SK Hynix has unveiled the world’s first 64GB DDR5 RAM modules, marking a big step away from DDR4 SIMs that have dominated PC memory since 2013.
Google commits to zero-waste data centers
So much of the world runs on Google, be it Docs, Gmail, YouTube or just search. But few of us know that much of what keeps the whole thing chugging along is the company's data centers, located all around the globe. And, as you might expect, it takes a lot of power and resources to do all that data churn, which is potentially quite wasteful. Thankfully, however, the search giant has committed to a new initiative called Zero Waste to Landfills so that all of the waste from those data centers will be reused or diverted to a more sustainable route.
Google puts money into cementing green energy standards in Asia
Plenty of big tech companies are looking to source green energy whenever they can for their substantial energy needs, and Google is the same. But it looks like it's hard to find the renewable energy you're looking for in Asia -- specifically China, which is why the company says it's offering seed funding to the Center for Resource Solutions. The non-profit is going to bring its experience in setting up and running renewable energy certification programs to Asia, starting in Taiwan. That's good, because that's right where Google needs green power for its data center.
Google makes big clean energy purchase to power data centers
Powering Google's online empire takes a lot of energy, and the company wants to use all clean sources to run its data centers by 2025. The company announced the next step towards that milestone today with word that it purchased 842 megawatts of renewable energy on three continents. The purchase includes solar and wind power in locales that range from North Carolina to Chile and Sweden, doubling what it had bought so far. Google says today's announcement is the largest purchase of clean energy by a non-utility company ever.
Google gives the world a peek at its secret servers
Google has given everyone a rare look inside its server rooms and detailed how keeps up with the massive growth of its search business. In a blog post, Google Fellow Amin Vadat said that the company's current network, Jupiter, can deliver a petabit per second of total throughput. That means each of its 100,000 total servers can randomly speak to each other at a speed of 10Gb/s, a hundred times faster than the first-generation network it created in 2005. To get there, Google did something surprising -- it built its own hardware from off-the-shelf parts.
IBM wants to cool data centers with their own waste heat
Those "do not eat" desiccate packets of silica gel that keep shoe boxes dry could soon help keep data centers cool. IBM has launched the THRIVE project with aims to do just that by creating a heat pump that runs on waste heat.
A virtual server bug is said to be worse than Heartbleed
In case you were napping, Heartbleed struck web servers' OpenSSL security last year, opening up the servers' memory to intruders. There's a new so-called zero-day vulnerability, only this time the researchers who discovered it say it's much worse, impacting millions of datacenter machines. The flaw is called Venom, which stands for Virtualized Environment Neglected Operations Manipulation. What does that mean? With the common practice of putting multiple customers into virtual servers, datacenters are setup to share some key tools, but sensitive information remains separated. Thanks to Venom, though, a hacker can gain access to a datacenters' entire storage network, leaving all of the customers on it vulnerable. As you might expect, the issue resides in an often ignored virtual floppy disk controller, but when it's exploited, it's like opening up a vault of stored info. As ZDNet reports, many modern virtual systems contain the bug -- platforms like Oracle's VirtualBox, KVM and Xen. The good news is Oracle says it already remedied the issue, and will nix it completely in forthcoming update. [Image credit: Marvel via Getty images]
Apple's data centers now powered by 100% renewable energy
Apple released the 2012 update of its environmental policy pages and notes that the company is now using 100 percent renewable energy sources -- solar, wind, hydro and geothermal -- at its data centers. The 100 percent renewable energy figure was also achieved at facilities in Austin, Texas; Elk Grove, Calif.; Cork, Ireland and Munich, Germany, as well as at the Infinite Loop campus in Cupertino, Calif. For all of Apple's corporate facilities worldwide, the figure is at 75 percent, and the company says that they "won't stop working until we achieve 100 percent throughout Apple." The company made a commitment to using 100 percent renewable energy at its data centers in 2012 after being criticized by Greenpeace over its energy usage. As the Apple video below demonstrates, the scope of the photovoltaic arrays used at the Maiden, N.C., data center is breathtaking. [via Bloomberg]
IBM manufactures light-based 'nanophotonic' chips to let the terabytes flow
IBM's taken a large step toward computer chips that use photons instead of electrons by manufacturing the first 90nm silicon-based optical processing modules. It did so using the CMOS nanophotonics technology we first saw back in 2010, creating tranceivers capable of 25Gbps transfer speeds. By multiplexing a large number of those streams to a single fibre, "terrabytes of data" per second could flow between distant computer systems," according to IBM. The 90 nanometer light circuits should allow data-hungry servers or supercomputers to scale up rapidly in speed "for the next decade, and at the desired low cost," according to the researchers. It's now primed for commercial development, meaning we could see an end to bottlenecks in systems "a few centimeters or a few kilometers" apart from each other.

Researchers turn to 19th century math for wireless data center breakthrough
Researchers from Microsoft and Cornell University want to remove the tangles of cables from data centers. It's no small feat. With thousands of machines that need every bit of bandwidth available WiFi certainly isn't an option. To solve the issue, scientists are turning to two sources: the cutting edge of 60GHz networking and the 19th century mathematical theories of Arthur Cayley. Cayley's 1889 paper, On the Theory of Groups, was used to guide their method for connecting servers in the most efficient and fault tolerant way possible. The findings will be presented in a paper later this month, but it won't be clear how effectively this research can be applied to an actual data center until someone funds a prototype. The proposed Cayley data centers would rely on cylindrical server racks that have transceivers both inside and outside the tubes of machines, allowing them to pass data both among and between racks with (hopefully) minimal interference. Since the new design would do away with traditional network switches and cables, researchers believe they may eventually cost less than current designs and will draw less power. And will do so while still streaming data at 10 gigabits per second -- far faster than WiGig, which also makes use of 60GHz spectrum. To read the paper in its entirety check out the source.
Facebook releases its 2011 energy usage report, details your carbon footprint
More Facebook news, but this time we're back to the numbers instead of reporting on a new feature, improvement or integration. As part of its mission to swap the familiar blue for something of a greener tinge, Facebook released today its carbon footprint and overall energy usage figures for 2011. Turning bio-babble into easy visualizations, the company points out that for the whole year, an active user occupied roughly the same carbon footprint as one medium latte. Or, if you're a fan of the tipple, a couple of glasses of wine. Impressively, 23 percent of the social giant's energy usage came from clean and renewable sources, which puts it well on the way to its 2015 target of 25 percent or more. If you'd like more info and a complete breakdown of the stats, the full report is available at the source link below.
Apple breaks ground on second solar farm for North Carolina data center
Last February, Apple came clean about its efforts to clean up the environment, detailing intentions to make its Maiden, NC data facility a greener place. That site, already home to one solar farm, is now set to host a second 20 megawatt photovoltaic array spanning 100 acres, a one-two power punch that'll jointly generate 84 million kWh annually. Combined with the company's in-development biofuel cell plant, scheduled for opening later this year, that theoretic yield should hit the 124 million kWh mark -- an amount sufficient to power nearly 11,000 households -- providing 60 percent of the center's electric demands. Still, that's not enough to adequately keep operations afloat, so for that very necessary, leftover 40 percent, the house that Jobs built plans to purchase similar clean energy from outside local sources. When all is finally up and running smoothly, the southern facility will earn the distinction of "most environmentally sound data center ever built." Or, at least until another well-heeled competitor comes along to contest that title. Now that's a friendly competition we can get behind.
Facebook's Open Compute takes on data storage, designs a better home for your photos
Facebook wasn't kidding when it said it wanted to build better backends for the digital world -- after sharing the plans for its customized data center, it's looking to do the same with storage hardware. "We're taking the same approach we took with servers," Frank Frankovsky, Facebook's director of Hardware Design, told Wired. "Eliminate anything that's not directly adding value." Frankovsky says they are working on a completely tool-less design, eliminating the need for mounting screws and plastic handles on hot-plug driver carriers. The goal is to get the outfit's new storage digs to run as efficiently as its previous efforts, streamlining hardware to be more serviceable, cost less and use less energy. The new storage designs are set to debut at the Open Compute Summit in early May, and hopes that sharing the designs will help redefine how storage hardware is made.

Apple's 2012 environmental report reveals giant solar array
Apple just released its 2012 environmental report, detailing all the ways it's conserving energy and working to make Mother Earth a slightly cleaner place. A highlight of that effort is clearly the company's data center in Maiden, North Carolina. The giant white-roofed server bunker will soon be home to the largest end user-owned solar array in the US -- covering 100 acres and producing 42 million kWh of electricity each year. The 20-megawatt installation is only the beginning too. A five-megawatt fuel cell facility will soon be going up alongside it. Hit up the source link for the full report, but be forewarned, it comes only in PDF format.
Google details its carbon footprint in new report, makes you think twice about Rickrolling someone
The folks in Mountain View have always been obsessed with performance, but until now, Google had never come clean with the nitty-gritty surrounding power usage. A new report published by the company tells all, revealing that the search giant emits 1.5 million tons of carbon annually; a figure roughly on par with the UN's operational footprint, or slightly more than the amount produced by the entire country of Laos. The docket also breaks down the carbon emissions by activity, too: individual searches yield 0.2g, ten minutes of YouTube emits 1g and the average Gmail user produces 1.2kg of CO2 over a year -- which on average equates to a grand total of 1.46kg of CO2 per plebe across its properties. According to Google, that's a figure that would have been higher had it not custom designed its data centers, achieving a fifty percent reduction in energy usage versus the industry average. Plenty of infographical delight awaits you at the source below.
Report: data centers accounted for just 1 to 1.5 percent of electricity use last year, Google claims less than 1 percent of that
You'd think, watching companies like Apple break ground on sprawling data centers, that the number of servers powering our untethered lives was on the rise. In a different decade, you might have been right. But not this one. According to a study prepared at the request of The New York Times, the number of servers in use has declined "significantly" since 2005. That's mostly because of the financial crisis of 2008, says lead researcher Jonathan G. Koomey of Stanford University, but we also can't discount the effect of more efficient technologies. What's more, he says, servers worldwide consume less energy than you might have guessed: they accounted for somewhere between 1 and 1.5 percent of global electricity use in 2010. And while Google, the king of cloud computing, has been cagey about revealing just how many servers house its treasure trove of data, the company said that of that 1 to 1.5 percent, it accounted for less than 1 percent -- meaning, just a hundredth of a percent of all the electricity consumed last year. All told, data centers' energy consumption has risen 56 percent since 2005 -- a far cry from the EPAs 2007 prediction that this figure would double by 2010, with annual costs ballooning to $7.4 billion. Then again, this slower-than-expected growth could well be temporary. Though Koomey can't specify to what extent the financial crisis and technological advancements are to blame, he insists, broadly speaking, that we're primarily seeing fallout from the economic slowdown -- a stay of execution, of sorts, for those of us rooting for energy conservation.
Visualized: ring around the world of data center power usage
Facebook may have recently boasted about how energy efficient its data centers are, but it is still Facebook, and that means it consumes plenty of power regardless -- more than anyone else, in fact, according to Peer1's recent survey of the world's most visited websites. As you can see above, that bit of data has also been conveniently visualized by the company in a colorful chart (with a noticeable lack of green), and there's plenty more details where that came from for you to dive into in the infographic linked below.
Google signs 20-year deal to power data centers with wind energy
It's not the first investment Google has made in wind power, but anyone wondering about its commitment needn't look any further than the company's just-announced deal with NextEra Energy. It's agreed to buy wind power from NextEra's wind farm in Iowa for the next twenty years, which it says will provide enough power to supply "several" of its data centers. What's more, Google says that the size and length of the deal (taking 114 megawatts of energy off the market) will also lead to other indirect benefits for the wind power industry, and give NextEra the flexibility to invest in additional clean energy projects. Head on past the break for NextEra's press release on the deal.
Blizzard: We're working on the Comcast problem
Snowman Eyonix posted an update to the ongoing Comcast issues on the forums today: he says that Blizzard is talking to Comcast about the problem, and that they may have identified the problem in a third-party network between the affected folks and Comcast themselves. He says work on the issue is ongoing, and that while they don't have an ETA, he'll let us know when there is more to know.We don't know if the "third-party network" includes those Los Angeles datacenters that were being blamed earlier, and to be honest, we don't even know how widespread the problem actually is. A few of our writers are on Comcast -- most of us haven't had any problems at all, though one of our writers in LA is experiencing lag and the occasional disconnect.We'll keep an eye on Eyonix's thread and let you know if anything changes. At this point, it seems the problems are known and Blizzard is doing what they can to solve things.
