      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...

    2. Survey: rack density will keep creeping up and complexity is growing

      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 ...

    3. Data center managers plan for power density jumps

      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 ...

    4. 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 ...

    5. Microsoft Server Share Fading Fast

      Microsoft Server Share Fading Fast
      Netcraft’s latest numbers on web server market share are out, and show a sharp drop for Microsoft IIS. The June survey shows a decline of more than 7.8 million sites on IIS, dropping Microsoft’s server marker share from 28.3 percent to 24.8 percent, a drop of 3.5 percent. The falloff is even more dramatic in active sites, a separate metric Netcraft uses to differentiate between parked domains and actual web sites. Microsoft’s share of active sites plunged 7.6 percent in the June survey to 28 percent.

    6. 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 ...

    7. 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 ...

    8. Wanted: IT Energy Czars

      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. Where to ...

    9. Cooling Down By All Means by Doug Mohney

      Cooling Down By All Means by Doug Mohney
      Cooling, represented by the loud and noisy air conditioning units, is a major factor in the electrical bill and in the amount of carbonbeing pumped into the atmosphere. Reducing or even dumping the big blowers is becoming a major factor in data center design. IBM is working with Syracuse University and the State of New York to build a new computer data center for the University incorporating green features, reports CNET News. Among the more innovative features being rolled into the testbed/showcase facility is a liquid cooling system using double-effect absorption chillers to convert exhaust heat from the facility's microturbines into chilled water to cool the data center's servers; enough excess capacity is expected to be available to handle the needs of an adjacent building.

    10. Solar Power at Data Center Scale

      Solar Power at Data Center Scale
      Solar Power at Data Center Scale Solar power has finally reached data center scale. Phoenix IT infrastructure provider i/o Data Centers is installing a huge array of solar panels on the 11-acre roof of its new Phoenix ONE data center. The company says the photovoltaic panels will generate up to 4.5 megawatts of power to supplement the energy needs of the massive facility. The installation planned for Phoenix ONE will dwarf all previous efforts to integrate solar power into a working data center. Its output will be nearly three times the 1.6 megawatts produced by the solar panels covering the roof of the Googleplex.

      Are You Running Out of Power or Cooling?
      How do you extend the value of what you have and plan for what you need? Data centers are packing in more power-hungry, heat generating IT systems than ever, and many power and cooling systems are reaching their limits. Older power protection, power distribution and HVAC systems could be bottlenecks to needed expansion. Since these support systems represent 40 percent of the cost of IT equipment, a wholesale upgrade is generally not an option. So, what is the best way to augment and extend existing capacity within the constraints of tight budgets and limited support staff? How can you establish a power and cooling infrastructure that is ready for growth but not over-provisioned for an uncertain future? This Eaton white paper offers strategies that enable IT managers to: Plan a more efficient and adaptable power and cooling infrastructure, starting with an audit of the present state and evaluation of alternative ...

    13. Quincy Plans Recycled Water for Microsoft

      Quincy Plans Recycled Water for Microsoft
      The city of Quincy, Washington is spending millions of dollars to build a system to supply recycled water for huge data centers operated by Microsoft Corp., Yahoo, Intuit and Sabey Corp. The system will allow Quincy to shift the data centers’ water requirements to a separate “gray water” system rather than depleting the city’s potable water supply. The water recycling program is similar to one implemented in San Antonio, which Microsoft cited as a key factor in its choice of the city for a $500 million data center. It reflects a trend in which municipalities and data center operators are working to minimize the impact of these facilities on local water systems. The Quincy project, which will treat up to 5 million gallons of water a day, will cost $9 million. The first phase is being built with a $4.5 million grant from the state, according to the ...

    14. Demo versus Retro by Doug Mohney

      Demo versus Retro by Doug Mohney
      Building a showcase energy-efficient data center from the ground up is all the rage these days. Fewer companies want to talk about retrofitting existing data center facilities to be more green. For instance, Holyoke, Massachusetts is the latest city to join the from-the-ground-up energy-efficient showcase list. The University of Massachusetts, MIT, EMC and Cisco are getting together to building a "world-class green research high-performance computing center." Western Mass would seem to be an unlikely place to put a data center, but Holyoke – 90 miles from Boston and 10 miles way from Springfield - has cheap and clean hydroelectric power available from the Connecticut River, a good start for building a green data center.

    15. PUE and Total Power Usage Efficiency (tPUE)

      PUE and Total Power Usage Efficiency (tPUE)
      I like Power Usage Effectiveness as a course measure of infrastructure efficiency. Its gives us a way of speaking about the efficiency of the data center power distribution  and mechanical equipment without having to qualify the discussion on the basis of server and storage used or utilization levels, or other issues not directly related to data center design. But, there are clear problems with the PUE metric. Any single metric that attempts reduce a complex system to a single number is going to both fail to model important details and it is going to be easy to game. PUE suffers from some of both nonetheless, I find it useful. In what follows, I give an overview of PUE, talk about some the issues I have with it as currently defined, and then propose some improvements in PUE measurement using a metric called tPUE.   What is PUE? PUE is defined in ...

    16. Are tiny processors the future of green data centers?

      Are tiny processors the future of green data centers?
      Think virtualization in a data center, and you most likely think of the latest generation of multi-core chips, such as Intel's recently released Nehalem-EX processor, which comes with eight cores a a whopping 2,300,000,000 transistors. But the future of green data centers may be in the opposite end of the spectrum, with server clusters built using many small, power-efficient processors. The Power of Software blog gives a very good rundown about the possibility of using small computers and processors instead of large ones like the Nehalem-EX. It mentions the Dell XS11-VX8, also called "Fortuna." The Via Nano powers Fortuna, and it's a 64-bit chip that offers hardware virtualization for Hyper-V. Amazingly, it uses only 29 watts when at full load, and 15 watts when idling, according to the blog --- less power than a UPS uses. Load up plenty of these devices and you can get ...

    17. Saving Green by Going Green by Tate Cantrell

      Saving Green by Going Green by Tate Cantrell
      It’s no secret that companies today are facing mounting pressure from government agencies, media and the concerned public to take major steps in reducing the environmental impact of their traditionally power-hungry data centers. Their efforts range from implementing basic energy assessment programs and enacting green design initiatives to using more eco-friendly materials and seeking out new power sources. In today’s tough economy though, it can’t be just about going green for goodness sake. Smart companies are seeking out opportunities for environmental projects that also work to whittle away at the corporate bottom line. Search for an area of rising cost where a reduction has an overall environmental benefit to a company’s green portfolio. Energy is the most obvious example. As such, power consumption has become a popular target area for greening a data center, but as companies are finding out, it’s not sufficient on its ...

    18. Researchers speed up the chase for cooler data centers

      Researchers speed up the chase for cooler data centers
      With energy costs rising and data centers at the core of IT strategy for many companies, cooling the growing number of computers jammed into data centers is an issue that has taken center stage. Some innovative university researchers are focusing on cutting the cost of cooling the hot racks of servers in data centers. Last month, Syracuse University teamed with IBM to create one of the world's most efficient data centers on the school's campus, while the Georgia Institute of Technology announced last week that its faculty had created a 1,100-square-foot testing facility where researchers can test new cooling designs and measure the impact that the designs have on power efficiency. [ For more data center news and expert advice on data center strategy, see CIO.com's Data Center Drilldown section. ] The Georgia Tech researchers aim to analyze power consumption "all the way from the chip to ...

    19. Vendors pitch stripped-down servers to giant Web properties

      Vendors pitch stripped-down servers to giant Web properties
      The explosion of giant Web properties has server vendors building a new kind of machine that is stripped down to the bare essentials and optimized for cost- and energy-efficiency, analysts say. The latest entry comes from HP, which on Wednesday introduced a line of x86 servers designed for what HP calls "extreme scale-out" environments. The HP ProLiant SL servers have a layout that lets fans run at lower speeds, and omit features that HP says often aren't required by large Internet companies, such as redundant power supplies and advanced management software. But HP is not the pioneer in this scale-out server market, with companies such as IBM, Sun, Dell, Super Micro, and Rackable offering products of their own. Each vendor has its own approach, but in general these are "systems optimized for large homogenous application scale-out deployments, an application that spans 1,000 servers," says Forrester Research analyst James ...

    20. HP Retools Cooling Management Solution

      HP Retools Cooling Management Solution
      HP has repackaged its data center cooling management tool, hoping a new scaled-down version will resonate with a broader set of data center customers. The HP Data Center Environmental Edge solution combines wireless sensors and management software to give data center operators a visual overview of the temperature in their racks. Environmental Edge is a stripped-down version of Dynamic Smart Cooling (DSC), the flagship cooling management solution HP began selling in 2007. Like DSC, the new cooling solution is designed to provide precise management of air conditioning systems in response to changes in server temperatures. The system deploys sensors throughout the data center, which take regular readings and report the results back to HP’s Environmental Observer visualization software.

      HP High Efficiency Cloud Infrastructure Servers, Moving Away from Blades, Learning from Data Center Operation
      Notice how IBM, Dell, Rackable, and Dell’s high efficiency cloud infrastructure servers are not blade enclosures? Maybe it’s because HP’s data center design group who creates solutions like this are figuring out how inefficient blades are for Cloud Computing. Quoting HP’s press release. With the HP ProLiant SL portfolio, customers can cut acquisition costs by 10 percent and power draw by 28 percent, while doubling their compute density.(2) “Customers with scale-out business models need solutions that make every dollar, watt and square foot in the data center count,” said Christine Reischl, senior vice president and general manager, Industry Standard Servers, HP. “The HP ProLiant SL offers pioneering customers like these the most significant design innovation since the blade form factor, allowing them to achieve an economy of scale never before possible.” And, HP includes an IDC quote. “Businesses built on extreme scale-out environments, such as ...
