      Q&A: The man who helped raise server operating temperatures
      Next month is the one year anniversary of a guideline by the American Society of Heating Refrigerating and Air-Conditioning Engineers (ASHRAE) that recommend increasing (PDF document) the temperature of air entering servers and other data center equipment. This increase of 77 degrees Fahrenheit to 80.6 degrees may not seem like a big deal, but it took a year-and-half of work to arrive at this recommendation and agreement by most of the major equipment vendors. The person who led the society's IT team on Technical Committee 9.9 was Roger Schmidt, an IBM fellow and its chief engineer for data center energy efficiency. It's unknown how many data centers have adopted the recommendation, or even have enough control over their environments to safely regulate air flows. Ken Brill, executive director of the Uptime Institute in Santa Fe, New Mexico, said he sees more understanding that the data center ...

      ThermoCabinet: 2,500 Watts A Square Foot
      Last week i/o Data Centers officially took the wraps off its ThermoCabinet offering for ultra high-density high computing. We got an advance look at the patent-pending design when we visited i/o’s Phoenix ONE data center in early June. The ThermoCabinet is sealed for complete isolation of hot and cold air, and can support computing power loads of up to 32 kilowatts per rack - the equivalent of 2,500 watts per square foot. Cool air movies directly from the raised floor into a chamber in the front of the cabinet, then moves through the servers and exits through a hot air chimney at the rear of the cabinet.

    4. Microsoft to Open Two Massive Data Centers

      Microsoft to Open Two Massive Data Centers
      Microsoft will open two new data centers in July, following through with a massive expansion of its data center capacity to support the company’s push into online services. The two new facilities in Dublin, Ireland and Chicago will add more than 1 million square feet oif space to the company’s data center network. The Dublin, Ireland data center will go live this Wednesday, July 1, followed by the Chicago data center on July 20. The two launches indicate that Microsoft has resumed its data center expansion after announcing a construction slowdown earlier this year. In January, Microsoft said it would postpone its planned data center in West Des Moines, Iowa and would bring Dublin and Chicago online “as customer demand warrants” based on quarterly reviews of data center capacity.

      Iceland: Refrigerating a green data centre
      ICELAND: According to Tate Cantrell, the Chief Technology Officer of Verne Global, the Data Centre industry has a real need for a clean energy solution that drives down overall cost. Iceland, he believes, offers such a solution. Verne Global is constructing a green data centre in the Asbru community of education and entrepreneurs on the former NATO military base in southwest Iceland next to the Keflavik International Airport. Since the US military left the base in autumn 2006, the area has seen an impressive revitalization as a student campus and a technology park. In addition to Verne Global, the Asbru area has been attracting attention from other industrial companies interested in investing in sustainability and green innovation using clean energy from Icelandic hydroelectric and geothermal energy sources. A clean energy research lab (Keilir) and a clean energy business incubator (Eldey) are all a part of the area's strategy of ...

    6. How to Be Virtually Green

      How to Be Virtually Green
      It's very interesting to me how certain principles can be broadly applied across industries. Take the principle of load diversity and full capacity utilization. This principle is used to great effect in the power sector, data centers and in some instances, buildings. In the power sector, electricity load-shifting was introduced in the late '70s and has enjoyed reasonable popularity ever since, particularly when a utility's generating reserve margin was low. Load-shifting means providing incentives for running certain equipment off-peak instead of on-peak. Perhaps the best-known example is the use of ice storage for off-peak cooling. Some engineers hate ice storage because it is "less efficient" than stand-alone chillers. In the small picture, this is correct. An ice storage system will use 7 percent to 8 percent more kWh than a chiller-only system yet, overall, using ice reduces CO2 emissions and fuel use, not to mention save tons of ...

      Energy-efficient servers earn a star -- but so what?
      Computerworld - Servers can now earn the U.S. Environmental Protection Agency's Energy Star label in recognition of their green qualities, but most observers aren't expecting this program to cause substantial changes in how enterprises buy servers anytime soon. The Energy Star server certification went into effect on May 15 and has earned the EPA kudos from manufacturers and users for promoting energy efficiency in an area that's notorious for its high electricity needs. "This is a great first step. It's been important for some time, given the power issues of the data center, to give transparency on the energy use of servers," says Subodh Bapat, vice president and distinguished engineer in the sustainability office at Sun Microsystems Inc.

      Water-Cooled Supercomputer Doubles as Dorm Space Heater
      Massive supercomputers that devour electricity to keep them humming are not exactly the poster children for green technology. But IBM hopes to change that with its plans to build a supercomputer that will use water to keep the system cool and even recycle some of the waste heat to help heat the university where it’s housed. The technology could lead to a reduction in overall energy consumption by at least 40 percent, when compared to similar air-cooled machines, says the company. “Energy is arguably the number one challenge humanity will be facing in the 21st century,” says Dimos Poulikakos, lead investigator of the project. “We cannot afford anymore to design computer systems based on the criterion of computational speed and performance alone.” Supercomputers are used in energy research labs such as Argonne National Laboratory, in space research by NASA and at universities for scientific research, all applications which have ...

      IBM Delves Into Lithium-Air Batteries, Water-Cooled Supercomputers
      The computing giant is researching lithium-air batteries, a technology with much promise but many challenges for commercial applications. Also in the works is a supercomputer cooled with water at the chip level – something IBM says could apply to broader data center cooling. IBM is busy looking for ways to make lithium-air batteries with 10 times the storage capacity of their lithium-ion cousins, and it has a Swiss supercomputer being cooled with water at the chip level – the technology could find its way into cooling data center servers and other IT equipment. Both projects announced Tuesday represent moves by the computing giant to get into more energy-efficient pastures, so to speak. In the case of its water-cooled supercomputer, IBM is hoping to find more efficient ways to cool the IT equipment. The equipment takes up about 2 percent of the world's energy. The project with the Swiss Federal Institute of ...

      Data Center Energy & Power Issues
      The priority list for today’s data center manager is longer than it’s ever been. Beyond the more traditional goals of maximizing uptime and optimizing floor space use, today’s list now includes running as efficiently as possible and ensuring the facility’s future power needs will continue to be met. Unlimited power is no longer a given, and planning and management strategies must evolve accordingly. Toward An Uncertain Future “Bringing power into data centers was always a given,” says Mark Harris, vice president of strategic marketing for Avocent (www.avocent.com). “Data centers didn’t think about whether or not they had enough power. They just called the facilities department up and asked for them to bring in more.” As energy costs continue to rise and availability comes into question, IT is learning to manage power just as proactively as it’s always managed technology. “You need to ...

      Taking Control Of The Power Bill
      Increasing heat loads, limited power resources, and other such constraints are forcing many admins to revamp their IT infrastructures’ power needs to accommodate growth, but the chief concern is costs. According to a study that Symantec recently published, 1,052 firms surveyed that spent $90 million to $100 million per year on IT used 16 to 20% of their total IT budgets on electricity alone. Reducing electricity costs by just 5% per year can thus translate into millions of dollars in cost savings for these enterprises and up to $20,000 annually for enterprises with $1 million-per-year IT budgets. With power accounting for such a significant chunk of spending, there are obvious incentives to reduce electricity consumption. However, many admins struggle with having to pay additional costs associated with investing in more eco-efficient cooling, airflow designs, and other related equipment. But the good news is that there are plenty of ...

      Some like it cool: Hp/eds fellow shares data center best practices
      I spoke last week with Ed Kettler, a fellow for Hewlett-Packard who comes to the company via HP's acquisition of systems integrator EDS. Kettler has been involved with two major data center overhauls that EDS undertook before it became part of HP, including the retrofit of a facility in Wynyard, United Kingdom, that sucks up 40 percent less energy than a typical data center of comparable size. According to an EDS positioning paper about green IT, about 70 percent of potential energy being sent to a data center is lost during the transmission. THEN, about half of the remaining 30 percent is devoted to items such as lighting, uninterruptible power supplies and cooling systems. That means a whole lot of...

      Survey: rack density will keep creeping up and complexity is growing
      Facilities and network energy efficiency ranks among the top concerns of almost half of data center, facility and IT managers surveyed recently. Fifty per cent reported that adequate monitoring was one of top three concerns. The survey revealed that about 60 percent of respondents had to cut their budgets because of the poor economy and 35 percent delayed new build or expansion projects. More than half of respondents said future facilities would be designed to support densities of 10KW and 20KW per rack, while current facilities support an average of 7.4 KW per rack. Reasons behind higher density were pressure to save space, support for blade servers and reduction of energy costs. About half of the respondents said the complexity of their cooling, monitoring and power systems was increasing and about half conducted power and cooling assessments to deal with the complexities. Of those who undertook assessment projects, 74 ...

      Data center managers plan for power density jumps
      A recent survey of Emerson Network Power and Liebert data center users found that respondents plan to double the power densities in their racks in future facilities. The Data Center Users Group survey asked about 120 data center managers questions on data center efficiency. Energy efficiency is now one of the top three concerns for nearly half (47%) of survey respondents, a result that surveys over the past year or so have confirmed. In a similar survey by the Data Center Users Group (DCUG) four years ago, energy efficiency was hardly ever listed as a top concern. Among the findings was that data center managers now design future facilities to handle 15 kW per rack on average, more than double the 7.4 kW-per-rack average today. Langan Integrated Engineering and Environmental Solutions Inc. is one company that has built more efficient facilities. The Elmwood Park, N.J.-based engineering firm ...

    18. Energy Stars: Wall Street Firms’ Sustainable IT Efforts

      Energy Stars: Wall Street Firms’ Sustainable IT Efforts
      No Wall Street firm could declare its data center truly "green." After all, a fully loaded data center draws somewhere between 7 and 40 megawatts (millions of watts) of electricity, enough to power thousands of homes. According to the Environmental Protection Agency, the energy consumption of the nation's data centers will exceed 100 billion kilowatt hours by 2011, ringing up annual electricity costs of $7.4 billion. But some data centers hog less energy than others (see related article on Citi's LEED-certified facilities). And although most firms have ditched the unrealistic phrase "green IT" for the more practical (and perhaps deliberately vague) moniker "sustainable IT" -- sustainable in the sense of its impact on the environment and budgets -- they are achieving real efficiencies. Wall Street firms are deeply engaged in virtualization, consolidation and other energy-efficient initiatives; they're even shutting down entire data centers, turning off servers and desktops ...

    20. LEED for Data Centers Coming Soon?

      LEED for Data Centers Coming Soon?
      Data centers are energy hogs, but the country’s most prominent green building standard, LEED, doesn’t adequately address their special design considerations. That looks set to change, however, as the U.S. Green Building Council, which develops LEED, is considering tailoring existing LEED rating systems to evaluate green data centers. Brendan Owens, the Green Building Council’s vice president of technical development for LEED, tells us that as part of that effort the nonprofit organization is also evaluating which tools would be best for assessing green data centers. Owens said that he is actively working with The Green Grid and other groups that have been doing detailed technical work on establishing benchmarks for green data centers. Any provisions added to LEED regarding data centers would draw from this technical work. But he would not give a timeline, stressing that a final decision has not yet been made. “It will ...

    21. Manitoba to Data Centers: No Thanks!

      Manitoba to Data Centers: No Thanks!
      Last year we reported that a number of large data center builders were investigating Manitoba as a location for power-hungry server farms. With power costs driving many data center site location processes, and corporate mandates for “green” facilities, the central Canadian province’s ample supply of affordable hydro and wind power is attractive. In early 2008 Manitoba Hydro was approached by several name-brand data center builders. Although data center companies are interested in Manitoba, it turns out Manitoba isn’t much interested in data centers. That’s the word from Manitoban blogger Rod Edwards. “I called the provincial department of Science, Technology, Energy and Mines (STEM), and had a very nice conversation with a representative who told me that Manitoba had, in fact, been contacted by a number of large datacenter investors, and that we had declined to compete for their investments,” Edwards reports. It turns out Manitoba Hydro would ...

      Wanted: IT Energy Czars
      Companies need them to help reduce operating and capital expenses. Do you have an IT energy czar? If you don't, you should. This is a relatively new job function and often one without sufficient horsepower to make serious business impact. That's unfortunate for the bottom line because energy savings directly translate into reduced spending on new data centers or capacity expansions, which have dominated at least half of IT's CapEx spending over the last few years. The Uptime Institute's research indicates that fewer than 8% of IT organizations have someone specifically accountable for reducing energy consumption. Another 44% have someone assigned to manage energy use, but without goals and clout. The percentage of czars has doubled within the last two years as management has learned the full extent of IT energy consumption on outgoing capital expenditure cash flow and the enterprise's bottom line.
