AC and DC Battle For Data Center Efficiency Crown

1sockchuck DC advocates trying to get on the same page (168 comments)

The effort to gain acceptance for DC distribution in data centers is being helped by a series of investments by ABB, and the growth of the EMerge Alliance, which is trying to unify DC proponents around a 380V standard. The challenge for DC is that customers don't ask for it, meaning multi-tenant facilities aren't likely to offer it. Also, Schneider says it is "not aware of any data centers moving off of their established, traditional power distribution to DC." In fact, NTT has at least five DC data centers in Japan, and ABB is backing a DC distribution project at a Swiss hosting company. In the US, there are numerous sites testing DC power, which is widely used in telecom infrastructure.

Obama Administration Closing Recently Opened Datacenters

1sockchuck Timing: Consolidation Began Two Years Ago (262 comments)

The federal data center consolidation effort began early in the Obama administration. After nearly a year of planning, the effort kicked off in March 2010. Many of these older data centers predate the Bush administration. Plenty of blame to go around, but Obama and his IT team have been the first to attempt to tackle a consolidation effort.

Why Waste Servers' Heat?

1sockchuck Links: Some Good Working Examples (204 comments)

As others have noted, there are many good examples of data center reusing waste heat. Here's a list of examples of server heat being recaptured to warm homes, offices, greenhouses and even swimming pools. This is common enough that The Green Grid recently released guidelines on the best way to integrate heat recapture in key efficiency metrics like PUE (Power Usage Effectiveness).

Level 3 Shaken Down By Comcast Over Video Streaming

1sockchuck Or is it Just A Noisy Peering Dispute? (548 comments)

Comcast says the issue with Level 3 is a peering dispute and says it "offered Level 3 the same terms it offers to Level 3s CDN competitors for the same traffic." The issue seems to be that the Level 3's addition of Netflix as a customer may have altered the balance of the traffic exchange between Level 3 and Comcast. In other words, Comcast says the volume of traffic is the issue, while Level 3 says the type of traffic is the issue.

In Oregon, Wind Power Surges Disrupting Grid

1sockchuck In Texas, the Opposite Problem (506 comments)

There are several ways that variable wind generation loads can present challenges. Texas, which has a large concentration of wind generation facilities, experienced an incident in early 2008 in which a sudden dropoff in wind triggered a grid emergency. A cold front came through, generation dipped, and utilities had to implement power shaving strategies, primarily reducing service to large customers who trade lower rates by being "interruptible."

10,000 Cows Can Power 1,000 Servers

1sockchuck This is already being built in the UK (221 comments)

The concept HP described in an academic paper is not new, and is already being built into a UK data center that has won awards for its approach. The Infinity ONE data center in East Anglia, England is working with a local farming co-op to use cow manure to power a combined heat and power (CHP) plant that will provide electricity for the data halls. The data center is already operational (using utility power) and expects to integrate the poop power sometime this year.

Extended Warranty Purchases Up 10% This Year

1sockchuck It's about the sellers, as well as the buyers (253 comments)

The increased sales of warranties are driven by the difficulties faced by electronics retailers. In an environment where there are fewer customers, stores look to increase the revenue per customer, and the easiest way to do that it to pressure sales associates to sell more warranties. It's an emotional decision ... the conversation takes place at the checkout counter, and rarely in a context where the shopper can take time to make a reasoned, fact-based decision. The desire to get extended life out of the product is no doubt providing an incremental sales boost. But the upsell is getting more forceful, and that's certainly about the economic concerns about the retailer, not the consumer.

Dell Buying Perot Systems For $3.9 Billion

1sockchuck This deal is about health care (92 comments)

This is all about Dell buying service revenues in health care and government, two areas that are getting s huge boost from the Obama stimulus package. In today's conference call, Perot Systems said it gets 48 percent of its revenue from the healthcare sector, and 25 percent from government. That's a strong footprint in two key growth areas, which is why Dell is paying a 65 percent premium to Friday's share price for Perot.

Liquid Cooling on the Rise as Data Centers Crunch Bigger Data

1sockchuck 1sockchuck writes  |  about two weeks ago

1sockchuck (826398) 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."

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

1sockchuck 1sockchuck writes  |  about a month ago

1sockchuck (826398) 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."

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

1sockchuck 1sockchuck writes  |  about 2 months ago

1sockchuck (826398) 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."

The Data Dome: A Server Farm in a Geodesic Dome

1sockchuck 1sockchuck writes  |  about 4 months ago

1sockchuck (826398) writes "In a unique approach to data center design, the new high-performance computing center in Oregon is housed in a geodesic dome. The new facility at the Oregon Health and Science University requires no mechanical air conditioning, using outside air to racks of servers reaching densities of 25kW per cabinet. The design uses an aisle containment system to separate hot and cold air, and can recirculate server exhaust heat to adjust cold aisle temperatures in the winter. It's a very cool integration of many recent advances in data center design, combining elements of the Yahoo Chicken Coop and server silo in Quebec. The school has posted a virtual tour that provides a deep technical dive."

Huge Bitcoin Mines Spring up in Warehouses, Some Data Centers Remain Wary

1sockchuck 1sockchuck writes  |  about 5 months ago

1sockchuck (826398) writes "What will the future of Bitcoin infrastructure look like? The Bitcoin mining craze is driving the creation of "hashing centers" — huge high-density, low-budget mining facilities optimized for rapid changes in hardware and economics. These mining facilities are often built in old warehouses, and house servers on shelving from hardware stores, skipping the expensive power backup equipment found in most commercial data centers. This poses a challenge for service providers, who love big customers but are wary of the Bitcoin sector and its economics, incouding the focus on short-term contracts. Some data centers are adapting, deploying space optimized for crypto miners, with the network and cooling systems on UPS, but not the power supplies."

Data Center With A Brain: Google Using Machine Learning in Server Farms

1sockchuck 1sockchuck writes  |  about 7 months ago

1sockchuck (826398) writes "Google has begun using machine learning and artificial intelligence to analyze the oceans of data it collects about its server farms and recommend ways to improve them. Google data center executive Joe Kava said the use of neural networks will allow Google to reach new frontiers in efficiency in its server farms, moving beyond what its engineers can see and analyze. Google's data centers aren't yet ready to drive themselves. But the new tools have been able to predict Google’s data center performance with 99.96 percent accuracy."

Sears to Convert Old Auto Centers into National Chain of Data Centers

1sockchuck 1sockchuck writes  |  about a year ago

1sockchuck (826398) writes "Sears plans to convert dozens of Sears Auto Center stores into a national chain of server farms, saying it wants to be “the McDonald’s or Starbucks of data centers.” The strategy is an evolution of Sears Holdings' previously announced plan to turn old Sears and Kmart stores into IT centers. Instead, it will focus on the more than 700 Sears Auto Centers, which include many stand-alone cement buildings on mall perimeters. Ubiquity Critical Environments, the data center arm of Sears, will team with Schneider Electric to turn these sites into data centers. They'll use repeatable modular designs to add power and cooling infrastructure, targeting at least 23 smaller cities where there currently aren't many options for IT outsourcing."

Ballmer: Microsoft Has 1 Million Servers

1sockchuck 1sockchuck writes  |  about a year and a half ago

1sockchuck (826398) writes "Microsoft now has more than 1 million servers in its data centers, CEO Steve Ballmer said at last week’s Worldwide Partner Conference. In his keynote, Ballmer handicapped the size of the server platforms for the world’s leading cloud computing providers, saying Microsoft was second-largest behind Google (which reportedly had 900,000 servers back in 2011). Why is Ballmer talking about server counts? "I claim there really are almost no companies in the world, just a handful, that are really investing in scaled public cloud infrastructure," he said. "(Cloud) puts a lot of pressure on us to make sure that we have world-class infrastructure across the world ... And we are investing in that infrastructure." Many cloud players still don't disclose server counts. Here's a list of those who do."

New SuperNAP WIll Handle Even Hgher Power Density

1sockchuck 1sockchuck writes  |  about a year and a half ago

1sockchuck (826398) writes "The SuperNAP in Las Vegas is one of the world's most extraordinary colocation facilities. When the 400,000 square foot data center opened back in 2008, its size and ability to manage high-density server cabinets was unique among colo providers. It now has a neighbor: a new and improved SuperNAP built next door to the original building that features an updated rack containment system that incorporates thermal storage, and multi-mode cooling units with an on-board backup power system (using a flywheel). The new wrinkles extend the "ride-through" time to maintain cooling in the event of a power failure. That's a key consideration in a high-density data center, where things can heat up pretty quickly."
