  • Thom: Hello, everyone. I’d like to welcome you to the final Web cast of Emerson Network Power’s 2007 Business Continuity Leadership Series. I’m Thom Gall, and I’ll be your host. We’ve hope you’ve enjoyed this year’s series and that you’ll tune in again next for more actionable information to help you keep your IT systems running. As you know, our Web cast program is certified by the International Association for Continuing Education and Training. So attending a 1-hour Web cast qualifies you to earn one-tenth of a CEU training credit. Just check the box in your survey following the Web cast, and you’ll receive your certificate by mail within 2-3 weeks. Today, we’ll look at how to make energy efficiency improvements in your data center that will ultimately help cut energy costs. This presentation deck will be available to download after the Web cast – check the link in your thank-you e-mail. I’ll give a brief introduction of Emerson Network Power and its Liebert solutions, then we will move on to our presenters.
  • Thom: Now, onto our first presenter. Jack Pouchet is Director of Green Initiatives at Emerson Network Power. Welcome, Jack. Steve: Thanks, Thom. Thom: Jack, say one of our attendees has set he goal of reducing their energy costs. Where would you advise them to begin? Steve: That’s a great question, Tom. I’ll provide some background, then show where the biggest opportunities for savings are.
  • Data Centers have become the smokestack target industry of the new millennia. It is easy to understand why as the recent EPA report to Congress shows that data centers represent approximately 1.5% of our national electrical budget ranking in the top 6 industry users of electricity. And data centers are forecasted to grow at rates far in excess of the GDP.
  • The DOE and EPA along with industry leaders like Emerson Network Power have come together to develop and evaluate future use models based upon technology improvements, a focus on energy efficiency, and user characteristics that validate the concept that we can do far more with a lot less energy. The potential savings are huge. … When you see that we can look to save 20 billion kWh per year by 2015 .
  • So today’s focus… The entire data center industry along with DOE and EPA are focused today on making incremental improvements in all aspects of the data center that well explore in a few minutes. However within Emerson we are also working hand-in-hand with the power generation community to improve their process management along with other aspects of their operations to gain improved efficiencies at the source. A simple 2% improvement at the source would more than offset all of the savings to be had in the data center space. … today we’re going to go after data center efficiency .
  • Let’s talk about the typical data center… Data Centers are not only a significant portion of the national power budget they are also “on” and ready for business 24 hours a day, day in and day out. This includes weekends and holidays. Combine the practice of always leaving your lights on and then switching from lights to halogens, to power hungry arc-lamps and you have an idea as to why the DOE, EPA, Utilities, and State agencies are getting involved… … data centers are on 24 x 7 and the power demands are growing.
  • In order to improve our data center we must have an understanding of where the power goes. The folks at EYP Mission Critical Facilities have collected some great data in this area… Its important to note that you can not improve what you do not measure. If you haven’t developed the tools and methodologies to audit your data center you may want to have an initial assessment, a power and thermal audit, to establish a baseline. This is something that Liebert’s trained field organization can do you for and provide a detailed report of their findings to help guide you on the path to improved efficiency.
  • So efficient and/or green, knowing the difference… Going green is a different issue and may not be 100% linked.
  • Let’s take a look at this just for a second… You can be efficient but not green. Fill your house with CFLs and leave them on all day, much like having a house full of teenagers, and even with efficient lights you are not actual green. Your neighbor, empty nesters, with all incandescent lights only uses them as needed. Guess who has the much smaller carbon footprint? … We at Emerson are going to talk about efficiency.
  • So let’s take a look at opportunities to improve data center efficiency… The good news in data centers is that for most of us there are real steps we can take today that will yield measurable and meaningful improvements in operational efficiency. All of which will translate into a reduced operating expense. Many of which may qualify for rebates and incentives from your local utility, State, or other agency. … your CIO and CFO
  • Let’s take a look at the power… By following the flow of power we can identify the most likely places to improve our data center efficiency. It all starts with the building. Now this may be out of your control but if you are working with a sieve, a building without a good vapor barrier, leaky doors, leaky roof, etc. well its going to be hard to make a huge difference. So get those areas checked out and repaired first. Your IT equipment really dictates the rest of the equation. Every saving here is amplified by an almost equal savings in balance of plant. So push for the most efficient server, storage, and network devices as possible. Make 90% efficient power supplies a part of your enterprise class hardware specification. Turn-on and use the server power management feature when it doesn’t interfere with your OS and critical applications… … or perhaps more.
  • The next step would be to develop a check list of areas that you want to investigate… Again, if you have not conducted a data center audit look to engage a professional service such as Liebert to help you better understand areas for improvement.
  • Power supplies are a key element of every piece of IT hardware… … a one month payback.
  • So as we move past the IT hardware Cooling becomes the next focus for data center efficiency. There are many fine resources available to help in this area with ASHRE and their TC 9.9 report being one of the industry standards for room layout and airflow optimization. Simply put with today’s cooling schemes it is best to configure your data center in hot-aisle cold-aisle layouts and ensure your IT equipment is grouped in racks so they are all front to back in airflow or at least segregate the bottom to top hardware into known rack footprints. For the facilities professional you recognize the value of a tight envelope. This may be the time to go request funding to improve your building. Look to add, retrofit, or replace legacy systems with new CRACs that feature variable compressors, airflow capacity controls, high-efficiency motors, and Liebert’s unique iCom control that enables CRACs to work in unison eliminating the fighting mode where one may be in humidification while another is trying to de-humidify. These types of improvements will often qualify for utility and/or tax incentives or favorable depreciation rates making the return on investment quite favorable.
  • New paradigms in cooling are changing the way data centers are designed. The old row of CRACs around the perimeter of the room just doesn’t work by itself with today’s high-density servers. And with cabinet power requirements rapidly moving to 25 and 30 kWs or more its time to consider supplemental cooling systems such as the Liebert XD. We’ll show a few scenarios shortly. In going to such a scheme, especially with a new data center site, one should look to take advantage of the huge energy savings of XD systems, often 30 to 50%, and develop a hybrid cooling approach. Again, these systems can qualify for utility incentives. Sun was recently awarded almost a million dollars for such an approach at their Santa Clara campus.
  • You can enjoy savings today without ever moving to advanced high-density cooling systems. Start with your traditional CRAC units and make certain they embody all of the new high-efficiency options. While you are at it make certain you are using the most “green” refrigerant as possible. Okay, so there are places where Liebert can not only improve your efficiency but help you towards your “green” status as well.
  • If your data center is only running around 2 to 5 kw per rack today you may think this is not for you but high-density is coming quickly and date from IDC, Forrester, and the Data Center Users’ Group indicate that over 60% of data centers will be running out of power and cooling within the next few years. Sometimes its not a case of insufficient total cooling but rather it’s the inability to deliver enough cooling where you need it most – your new blade centers or other high-end enterprise class server cabinets. This is where supplemental cooling excels and it can save you money at the same time and extend the life of your data center.
  • So let’s take a look at opportunities to improve data center efficiency… The good news in data centers is that for most of us there are real steps we can take today that will yield measurable and meaningful improvements in operational efficiency. All of which will translate into a reduced operating expense. Many of which may qualify for rebates and incentives from your local utility, State, or other agency. … your CIO and CFO
