    1. Green IT: How Real Is ROI?

      Green IT: How Real Is ROI?
      Green IT puts companies in a dilemma. The rhetoric of cutting carbon footprint and being socially responsible corporate citizens is tempting. Given the media, government and vendor focus on the issue, and the urgency of the problems associated with environment, awareness is at an all time high. But Green IT comes at a cost and is more expensive than products of other hues. There is a premium to be paid for additional effort that goes into designing and manufacturing green products, for example power efficient batteries, that do offer value for money by delivering higher efficiencies.

      IBM claims 90% Top 20 Energy Efficient Supercomputers
      IBM will release on Monday, July 13 a press release on its energy efficient supercomputers. I don’t have the link yet, but below is the text. Ironically, I just sat down with a person at ARM to discuss energy efficiency and he was mentioning how in 2005 he asked about energy use at a super computing conference, and people would think he was asking a stupid question. It’s great to see the question “how much energy does your supercomputer use?” is now a normal part of a purchase decision. Note this quote below. "Modern supercomputers can no longer focus only on raw performance," said David Turek, vice president, deep computing, IBM. "To be commercially viable these systems most also be energy efficient. IBM has a rich history of innovation that has significantly increased energy efficiency of our systems at all levels of the system that are designed to ...

      Data Center Efficiencies Wait in the Wings
      For companies looking to slash their carbon footprint and gain energy efficiencies, the IT data center is a logical first choice.From re-evaluating the equipment in place to complete overhauls in server strategy, companies are looking to the IT department to take up the slack in an otherwise down economy. Here are some areas to find savings within data centers. Hardware reassessment Taking a good, long look at a company’s actual needs, versus what kind of equipment is in place, can result in savings of 5-10 percent, according to research from Gartner Inc., reports SearchDataCenter.com. Unnecessary or obsolete equipment can be eliminated. Performing server “rationalization” can result in savings of $400 per server per year. Some of the newer chips are much more energy efficient and operate at higher tolerances for heat, allowing IT cold rooms to run a little warmer. Virtualization Using one server to run many ...

      Exploiting the dogfood factor in corporate sustainability strategy
      On paper, at least, it sometimes seems like big technology companies have a built-in edge over other organizations in getting with the green IT program. Of course, I deal with technology companies for a living, so that’s just what I know the best. Take IBM, which released its latest report on corporate social responsibility earlier this week. I won’t regurgitate every single piece of that update, but I do what want to key in on is a couple of things that IBM has been doing that its seems to me every business should be striving to emulate. The first is really focusing on how your own products and services can help achieve your sustainability goals and the second is looking to your business partners to play a role. I call this the “dogfood factor.”

      Developer pushes for data center in valley
      A Boston company wants to build a data center in the Menomonee Valley that developers say will use less energy, offer lower costs and help spur area economic growth. Source IT Energy LLC has been negotiating with land owners on two sides of We Energies' Menomonee Valley power plant near 10th and Canal streets, said Herb Zien, the company's Milwaukee-based senior vice president and chief development officer. It plans to sell or lease space to research organizations and businesses, Zien said. Once filled, the data center would have 48 units that would house up to 100,000 total servers, he said. The 75,000-square-foot "server farm" could be operating by the first quarter of 2011 if developers can get commitments to fill it by the end of August and don't run into delays for transformers, chillers and other heavy electrical equipment, Zien said. They have a "reasonable expectation ...

      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 ...

      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 ...

    18. 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.

    20. Should Servers and Networking Come From a Single Source?

      Should Servers and Networking Come From a Single Source?
      Data center hardware infrastructure can be roughly categorized into servers, networking and storage. But two of those areas are merging before our eyes, as Cisco and HP battle for server and network integration. The business and technical implications of this consolidation affect other companies and customers — and the dust isn’t likely to settle anytime soon. Although Cisco fired the first shot with its Unified Computing System, HP has long held the keys to a successful server line and an equally successful — and often under-rated — ProCurve networking line. And while Cisco’s first server was chassis-based — akin to its current switch and router products, its most recent announcement includes support for 1U and 2U rack-mounted servers, the kind HP has been shipping for years, along with Dell, IBM, Supermicro, and many more.

      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.
