Submission Inside Amazon's Cloud Computing Infrastructure->

1sockchuck writes: As Sunday's outage demonstrates, the Amazon Web Services cloud is critical to many of its more than 1 million customers. Data Center Frontier looks at Amazon's cloud infrastructure, and how it builds its data centers. The company's global network includes at least 30 data centers, each typically housing 50,000 to 80,000 servers. "We really like to keep the size to less than 100,000 servers per data center," said Amazon CTO Werner Vogels. Like Google and Facebook, Amazon also builds its own custom server, storage and networking hardware, working with Intel to produce processors that can run at higher clockrates than off-the-shelf gear.

Submission 1 Million Square Foot Data Center Being Built in Dallas-> 1

1sockchuck writes: RagingWire has begun building a 1 million square foot data center campus in the Telecom Corridor north of Dallas. Data centers have been growing in scale for years, but this project reflects the extent to which massive amounts of computing power are being concentrated in regional hubs. This super-sizing of data center campuses allows cloud platforms (and the data center providers that serve them) to rapidly add server capacity and electric power.

Submission Connecting the Unwired World With Balloons, Satellites, Lasers & Drones->

1sockchuck writes: New projects are seeking to connect the unwired world using balloons, drones, lasers and satellites to deliver wireless Internet. There are dueling low-earth orbit satellite initiatives backed by billionaires Elon Musk (SpaceX) and Richard Branson (OneWeb), while Google's Project Loon is using balloons (which sometimes crash) and Facebook is building a solar-powered UAV (Project Aquila). A question for Slashdotters: How will data storage infrastructure evolve in wireless-only access zones? Are local data centers necessary? If so, how are they different than in markets with fiber infrastructure?

Comment Re:Modulating local water temps? (Score 3, Informative) 96

In a recent test, Nautilus says the water being returned to the bay was was just 4 degrees warmer than the intake temperature. Their design goal is to minimize the temperature differential to avoid any environmental impact. Having said that, the proof-of-concept test was with 5 racks of gear, rather than an 8 megawatt data center. They believe the design works, but it hasn't yet been tested at scale.

Submission Startup Builds Prototype for Floating Data Center->

1sockchuck writes: California startup Nautilus Data Technologies has developed a floating data center that it says can dramatically slash the cost of cooling servers. The company's data barge is being tested near San Francisco, and represents the latest chapter in a long-running effort to develop a water-based data center. Google kicked things off with a 2008 patent for a sea-going data center that would be powered and cooled by waves, conjuring visions of offshore data havens. Google never built it, but IDS soon launched its own effort to convert old Navy vessels into "data ships" before going bankrupt. Nautilus is using barges moored at piers, which allows it to use bay water in its cooling system,eliminating the need for CRAC units and chillers. The company says its offering may benefit from the growing focus on data centers' water use amid California's drought. But is the market ready for a floating data center?

Submission Bloom Energy and Fuel Cells in the Data Center: Evolution or Revolution?->

1sockchuck writes: It's challenging to make fuel cells work as a power source for huge data centers. But Bloom Energy is gaining traction among server farm operators, Some colo operators, like Equinix and CenturyLink, are test-driving the "Bloom boxes" in California and other markets where power is expensive, eBay has gone further, using gas-fueled Bloom Energy servers as its primary power source, with the grid as backup, operating without UPS units or backup generators. Bloom sees this approach as the key to solving the challenging economics of using fuel cells at data center scale.

Submission As Cloud Growth Booms, Server Farms Get Super-Sized ->

1sockchuck writes: Internet titans are concentrating massive amounts of computing power in regional cloud campuses housing multiple data centers. These huge data hubs, often in rural communities, enable companies to rapidly add server capacity and electric power amid rapid growth of cloud hosting and social sharing. As this growth continues, we'll see more of these cloud campuses, and they’ll be bigger than the ones we see today. Some examples from this month: Google filed plans for a mammoth 800,000 square foot data center near Atlanta, Equinix announced 1 million square feet of new data centers on its campus in Silicon Valley, and Facebook began work on a $1 billion server farm in Texas that will span 750,000 square feet.

Submission The IT Containers That Went to War->

1sockchuck writes: Parachuting a container full of IT gear into a war zone is challenging enough. In the mountains of Afghanistan, helicopters had to deliver modular data centers in three minutes or less, lest the choppers be targeted by Taliban rockets. UK vendor Cannon recently spoke with DataCenterDynamics, sharing some of the extreme challenges and lessons learned from deploying portable data centers for military units in deserts and mountains.

Submission Supercomputing Cluster Immersed in Oil Yields Extreme Efficiency->

1sockchuck writes: A new supercomputing cluster immersed in tanks of dielectric fluid has posted extreme efficiency ratings. The Vienna Scientific Cluster 3 combines several efficiency techniques to create a system that is stingy in its use of power, cooling and water. VSC3 recorded a PUE (Power Usage Efficiency) of 1.02, putting it in the realm of data centers run by Google and Facebook. The system avoids the use of chiillers and air handlers, and doesn't require any water to cool the fluid in the cooling tanks. Limiting use of water is a growing priority for data center operators, as cooling towers can use large volumes of water resources. The VSC3 system packs 600 teraflops of computing power into 1,000 square feet of floor space.

Submission Where Facebook Stores 900 Million New Photos Per Day->

1sockchuck writes: Facebook faces unique storage challenges. Its users upload 900 million new images daily, most of which are only viewed for a couple of days. The social network has built specialized cold storage facilities to manage these rarely-accessed photos. Data Center Frontier goes inside this facility, providing a closer look at Facebook's newest strategy: Using thousands of Blu-Ray disks to store images, complete with a robotic retrieval system (see video demo). Others are interested as well. Sony recently acquired a Blu-Ray storage startup founded by Open Compute chairman Frank Frankovsky, which hopes to drive enterprise adoption of optical data storage.

Submission BitFury Seeks to Alter Bitcoin Mining Economics With Immersion Cooling->

1sockchuck writes: One of Bitcoin’s biggest players is turning to immersion cooling to address the shifting economics of cryptocurrency mining. BitFury Group will acquire immersion cooling specialist Allied Control, which created a high-density bitcoin mine in a Hong Kong skyscraper. The mining chips will be immersed in a cooling fluid that boils at a low temperature. As the chips generate heat, the fluid boils off, removing the heat as it changes from liquid to gas. It allows ASICs to operate without fans, which are typically among the largest components of a bitcoin mining rig. BitFury will house its new ASICs immersion tanks in Allied Control's DataTank containers, which can be deployed near sources of cheap power or renewable energy.

Submission Liquid Cooling on the Rise as Data Centers Crunch Bigger Data->

1sockchuck writes: The use of liquid cooling will accelerate in the next five years, according to experts in high performance computing, who cite the data-crunching requirements of scientific research, cloud computing, bitcoin and "big data" analytics. “In the HPC world, everything will move to liquid cooling,” said Paul Arts, technical director of Eurotech. But there's still plenty of resistance from data center operators wary of bringing liquid near servers, and cost is also an issue. Liquid cooling can offer significant savings over the life of a project, but the up-front installation cost can be higher than those for air-cooled systems. Immersion cooling has gotten a surprise boost from the rise of bitcoin, including a large bitcoin mine inside a Hong Kong high-rise.

Submission Why Supercomputing Matters: At SC14, A Focus on Benefits of HPC->

1sockchuck writes: America’s high-performance computing (HPC) community faces funding challenges and growing competition from China and other countries. At last week's SC14 conference, leading researchers focused on outlining the societal benefits of their work, and how it touches the daily lives of Americans. “When we talk at these conferences, we tend to talk to ourselves,” said Wilf Pinfold, director of research and advanced technology development at Intel Federal. “We don’t do a good job communicating the importance of what we do to a broader community." Why the focus on messaging? Funding for American supercomputing has been driven by the U.S. government, which is in a transition with implications for HPC funding. As ComputerWorld notes, climate change skepticTed Cruz is rumored to be in line to chair a Senate committee that oversees NASA and the NSF.

Submission Can the Sun Power the Cloud? The Solar-Powered Server Farm at Scale->

1sockchuck writes: A massive solar array in central New Jersey provides the daytime power for a server farm delivering online financial services for McGraw Hill. The 50-acre field of photovoltaic solar panels symbolizes a new phase in the use of renewable energy in data centers. Massive arrays can now provide tens of megawatts of solar power for companies (including Apple) that can afford the land and the expense. But some data center thought leaders argue that these huge fields are more about marketing than genuinely finding the best approach to a greener cloud.
