  • Using Green IT To Get Into the Black - A How To Guide

    "Nowhere are the potential benefits of a green strategy more compelling than in the data center." That's according to our power & cooling guru, Dr. Albert Esser in his new article "Using Green IT To Get Out Of The Red And Into The Black" that was just published in The Environmental Leader.

    Also important in driving down costs is how an organization approaches power management across its PCs. A 2007 Gartner study estimates that 40 percent of global carbon dioxide emissions are due to PCs and monitors, while 23 percent are due to servers and associated cooling technology in data centers.

    Statistics like this are among the reasons why we continue to take aggressive steps in providing with the most energy efficient products in the industry. Today, we just announced a 25% energy efficiency improvement commitment for our laptops and desktops. Read more here.

     

  • Purdue punches out supercomputer in near-record time

    I got my bachelors ME degree at Michigan State and understand what competition means in the Big Ten.  You crush it when you can.  Well, the folks at Purdue University's Rosen Center for Advanced Computing crushed it on Monday. With a huge team effort, they installed their new supercomputer - including unboxing the equipment - in just half a day. C|net called it an "electronic barn-raising."

    The supercomputer, named Steele, features 812 Dell PowerEdge 1950 dual-quad-core computer nodes and is predicted to have a peak performance of more than 60 teraflops, which means it could perform more than 60 trillion operations in one second, placing Steele in the top 40 on the current Top 500 computers listTinkergeek has 249 photos of the install , which is probably some sort of record by itself.  You get to see them working on the raised floor, installing racks, rails, switches HVAC, power and network cabling.  My favorites are #s 79, 90, 152, 179, 200 and the last one - the rack with signatures of the team that worked on it - very cool.  They have a brisk stop action video too.  

    The HPCC will be used for research across a variety of disciplines, including engineering, biological, earth and atmospheric sciences, mathematics and physics. The leading researchers at Purdue pooled their grants and provided a majority of the funding for the cluster, which is housed at Purdue's Mathematics Building on campus.

    High-performance computing is helping to support research that benefits society and Purdue is one example of major universities using Dell technology to enhance their teaching, learning and research initiatives.

  • Green economics from the Uptime Institute Symposium

    I spoke this week at the Uptime Institute’s Symposium 2008. Green IT is a topic that undoubtedly is becoming more top of mind among CIOs and data center managers.

    Research from the Uptime Institute indicates that enterprise greenness is both socially responsible as well as economically smart. I couldn’t agree more.

    Greening your data center for efficiency is both good for the environment, since you’re lowering your overall CO2 emissions, and good for your pocketbook, since you’re able to reduce power consumption across your IT infrastructure. And this can be done without sacrificing performance. Dell analysis has shown that customers can lower their data center energy consumption by 45 percent while maintaining the same compute performance. This is the result of taking a holistic approach to data center energy efficiency which takes into account the synergy between hardware, power utilization rates, cooling and software solutions.

    Dell’s position is that you cannot afford not to be green. And the Uptime Institute would agree that the time to begin greening your data center isn’t sometime in the future – it is now. What questions do you have around the topics of Green IT or power & cooling? Let me know, and I’ll be sure to get back to you with answers.

  • Microsoft Management Summit is very hot and Dell is in the buzz

    A Dell employee emailed from the Microsoft Management Summit this morning:

    I am in the opening keynote here at MMS. Being the featured hardware partner for SCCM is awesome. The room is PACKED and attendees are hearing Microsoft talk about how great Dell systems management is.

    Microsoft’s Bob Muglia, MS SVP, highlighted Dell’s preliminary bare metal deployment pack in his keynote. Hubba hubba and hey now.

    Many of our customers use Microsoft’s System Center and Dell’s OpenManage to manage their infrastructure. And who do you think offers the most comprehensive device management through Microsoft’s System Center Suite? (Dell does) And we’re not resting. This week we’re announcing the upcoming availability of the latest Dell Management Packs for Microsoft System Center Operations Manager that will give customers superior monitoring and control of Dell desktops, portables, workstations, rack and tower servers, blades, networked storage devices and even printers.

    Our new plug-ins and our roadmap to integrate Dell Services with Microsoft products means our mutual customers will continue to have industry leading tools to manage their IT infrastructures. All this talk about simplifying IT really means something.

    Thanks for the kind words this morning Bob!

  • How much can you turn off?

    GreenBiz radio has an interview with Ken Brill of the Uptime Institute.  Its a bit long, but all the text is there so you can speed read through it if you want.

    One of the more interesting things that Brill claims is that lots of energy can be conserved by turning off equipment that isn't being used.  Here's a quote from the interview transcript:

    KB: Well, the institute believes that IT could radically reduce its energy consumption, and it would save money in the process. And there are a number of things that people can do and we're gonna be talking about these at our upcoming symposium. But the first thing that people can do is to go through their data center and identify what is running that could just be turned off. Between 10 and 30 percent of the energy consumption in a typical data center is for servers and storage and other things that is no longer in use.  And it could just be turned -- I mean, as literally, as simple as turning the switch.

    Ken has some interesting things to say about blade servers too. Just like any other technology, there are important differences in blade server designs.

  • How should we measure Earth Day?

    Earth Day is a day to reflect on our planet’s condition and to re-dedicate ourselves to the work that lies ahead. One of the keys to effective conversation is having good metrics that indicate the progress we are making. That’s why we became one of the founding members of The Green Grid, an international consortium of companies dedicated to improving energy efficiencies in data centers and business computing ecosystems. One of the first Green Grid initiatives was to develop standard measures of infrastructure efficiency. As we said in an earlier podcast, there was no standard way to determine if you had a data center that was wasting energy. During its first full year, The Green Grid has been very successful in promoting the first set of these measures: Data Center Infrastructure Efficiency (DCiE) and Power Usage Effectiveness (PUE).(PDF link)

    DCiE and PUE are reciprocal metrics that describe how efficiently a data center powers and cools its equipment. A DCiE of 33% (the equivalent of a PUE of 3.0) means that 33% of the total power use is going to the data center. A PUE of 3.0 means that 300 watts into the facility in order to deliver 100 watts to the IT equipment. The other 200 watts is overhead. Obviously, efficient data centers look to reduce that.

    Why are these measures so important? You can only improve what you can measure. Standardization is essential to the development of benchmarks, which then can be used for improvements. Individual companies cannot do this all alone, which is why The Green Grid is having such a seminal impact on improving efficiency in data centers. DCiE and PUE are just the beginning. We’re looking forward to expanding our work to include data center productivity, methods for assessing data center designs, operations and technologies to improve data center efficiency.

    Dell believes The Green Grid helps our customers directly address the power and cooling issues that they face. These efforts, along with our own, will not only increase data center efficiency, but provide the ReGeneration for a much more sustainable computing ecosystem. The February issue of Power Solutions magazine has a number of excellent articles to read (PDF link) that can bring you up to speed.

  • Blades @ Dell: Should we listen to customers or competitors?

    Our new M-Series Blades are getting noticed. Maybe it’s because we’re trying very hard to listen. Customers tell us that blading (is that a verb?) a data center isn’t a strategy, but it is a viable technology solution for power, space, cooling management, and performance requirements. More precisely they tell us they want blades that are modular and can be easily re-purposed as their needs change. Competitive blade offerings are designed for specific workloads with a small set of configuration options for memory and processor upgrades, but they don’t address infrastructure changes such as new network interfaces (10 Gig Ethernet) and switch architectures.

    Independent analysts like what they see. Gartner said our “positioning of its blade servers also differentiates it from competitors… Dell supports the premise that blades, racks and towers all demonstrate specific market competencies; it believes that, in the coming years, there will be room for all three. This premise is consistent with Gartner's view of the market.” You can also read what InfoWorld, BladeWatch and The Register said.

    Change is inevitable. The M-Series adapts to it with modular snap-in flexibility down to the switch interconnects. If you need to add more I/O bandwidth or want to upgrade your switches you can add upgrade modules to the M-Series on the fly. That’s the sort of simplicity our customers demand. They also want simple management of blade components. We’ve responded with the most efficient, greenest, lead-free, and fastest-to-deploy blades on the planet. Listen to a podcast describing it in more detail.

    We are trying to do the things that matter most to our customers. It’s our strategy and we are sticking with it.

  • Tech trends that will shape IT for the next five years

     

    TechRepublic recently ran an article by Jason Hiner about Gartner's predictions of the 10 technology trends that will shape IT.  In it, Mr. Hiner adds insightful comments, some of which inspired me to write this post.

    Gartner predicts that half of business travelers won't take their laptops with them by 2012.   The timing is perhaps aggressive but the idea is spot on.  Many people want smaller mobile systems, but there is probably going to be a point where small isn't necessarily better. Others want  larger laptops. Look at the newer notebook computers that have 20 inch monitors.  Some people want modular, multi-purpose devices - think "laptop/smartphone/PDA/emaildevice."   The range of products will undoubtedly expand.

    Gartner predicts that open source will penetrate 80% of enterprise software.  To put a finer point on it, they think 80% of enterprise software will include "elements" of open source.  I think it's an  improvement to substitute the words "standards based" for "open source." Why?  Ask, and I''l explain.

    The article says power efficiency will become key criteria in IT purchases.  We hear it from customers every day.  The convergence of limitations on power, cooling and space are hitting the entire IT infrastructure hard.  That's why we started years ago, and why we're delivering products and services today that address these issues head on.  We're already offering the greenest servers, client PCs and solutions on the planet.

    The CO2 footprint ("carbon footprint") of the data center, was also mentioned as becoming part of PC purchasing criteria.  We're well on our way to having a zero carbon footprint for our company by the end of this year.  Dell is the only company to offer free recycling for consumers and low-cost asset recovery services for business.  You can offset the carbon footprint of the entire life of one of our products with the "Plant a Tree for Me" and "Plant a Forest for Me" programs.  CO2 is still a pretty abstract concept for most people.  One way to think of it is that using an Energy Smart server that consumes 19% less power can save 3,200 watts per rack per year (about $30,000), which eliminates 18 tons of CO2 emissions, which equals about four acres of pine forest.  Please check out our credentials, and our Sustainability Report

    I also agree with the idea that end user preferences will drive many IT decisions.  IT organizations will govern the directions and architectures, but end users will drive what IT delivers to them as tools.  Tablet PCs, RFID devices, smart phones, email devices, telephony, fax, and other devices will all need to be interconnected.  Users will demand a single identity that travels with them and the ways they use and access information.

    In short, we agree with a lot of what's in the TechRepublic article, but differ over the timing.  What do you think? How fast is our IT world changing and in what ways?

     

  • It Ain’t Easy Being Green – We’re Getting There

    Dell just announced a very cool green initiative. The company will now run its 2.1 million square-foot global HQ campus – home to more than 10,000 employees - using “green” power exclusively. Obviously, that includes a lot of IT infrastructure to power, not to mention keeping the lights on or the building cool in the Texas heat.

    What is green power and where does it come from? According to the EPA’s definition – “ green power is a subset of renewable energy and represents those renewable energy resources and technologies that provide the highest environmental benefit. EPA defines green power as electricity produced from solar, wind, geothermal, biogas, biomass, and low-impact small hydroelectric sources. Customers often buy green power for avoided environmental impacts and its greenhouse gas reduction benefits.”

    In this case, Dell will be getting the power from two sources. Dell is using all of the power generated from Waste Management’s Austin Community Landfill gas-to-energy plant, meeting 40 percent of Dell HQ needs. The remaining 60 percent comes from existing wind farms and is provided by TXU Energy.

    Full news release, Dell’s 2008 carbon neutral commitment. Dane Parker, Dell’s director of environmental health and safety, has a post and video about creating a clean energy future on Direct2Dell.

    Good for the environment. Good for the company. Good all around.

  • HP Server Announcement is an April Fools

     

    HP got an early jump on April Fool’s day yesterday when they announced their new blade server, the Proliant BL260c G5, with the claim that it has 64% better energy efficiency than the Dell PowerEdge M600 blade server.  The details of this Internet Vaudeville act can be found here: http://h71028.www7.hp.com/enterprise/downloads/HP_ProLiant_BL260_SPECjbb2005_032808a.pdf

    Normally, vendors try to establish comparisons using similar configurations, such as those done by Principled Technologies here: Yes, Dell commissioned this work, but if you look at Appendix B of that report, you'll notice that a professional rigor was applied to making sure there was a level playing field.  By contrast, the HP report published yesterday makes no attempt at comparing similar configurations.  Different processors, running in different power modes with different memory and disk configurations, etc.

    If HP had substituted one of their own servers in place of the M600 – one that was actually comparable to the M600, such as the BladeSystem c-Class tested by Principled Technologies, the power savings would probably have been over 75%, instead of the 64% they reported.  But they couldn't very well come out and say that their high mileage lab experiment was so much better than an HP product that many of their customers already own.
