Forewordto 18 degrees although they could easily run at up to26° Celsius. Frequently, it is a cost-accounting problemthat lies behind this waste of energy: An organisation’senergy consumption often falls under the responsibilityof Facility Management. But companies who want to helpput Green IT on the map, cut expenditure and save energywhilst protecting the environment at the same time,need to place responsibility for their IT systems’ energyconsumption where the decisions are made: in the handsof the IT management.The current climate debate has increasingly brought thesubject of Green IT into the public eye. The predictedclimate change is threatening our planet and is going tohave a dramatic impact on our lifestyles. CO2 emissionswill have to be reduced very rapidly if global warming isto be curbed. While it is true that the ICT sector is responsiblefor roughly 2% of all CO2 emissions, it also has to besaid that it contributes around 6% of global value added.This sector’s energy efficiency is thus three times betterthan the average for all sectors.Martin Jetter, Member of the BITKOM Executive CommitteeGeneral Manager IBM GermanyChairman of the Board of DirectorsIBM Deutschland GmbHOver the next five years energy consumption will becomeone of the largest cost factors for many data centers.Borderstep Institute calculations show that data centerelectricity costs have already more than tripled between2000 and 2006. Yet investment in energy efficient productsand processes often pays off remarkably quickly:payback periods of 2 years and less are the rule here.But there is still a lot to be done: For years now, our branchhas been addressing the problem of how to reduce globalenergy consumption even further. Modern environmentalprotection requires hi-tech solutions. Climate change canonly be curbed with the help of innovative ideas and theintelligent application of ICT technologies.The ICT sector thus embodies the idea of climate protectionmore than virtually any other sector. But in order toinitiate the paradigm shift, we first need to make our ownproducts and solutions more energy efficient. Which iswhy this guide presents the latest available solutions forreducing costs and increasing energy efficiency.However, according to a survey carried out by marketresearchers Experton, only 7 per cent of German ITdecision makers are familiar with the energy requirementsof their own IT systems! So it’s hardly surprisingthat data centers are often expensively cooled down4
Energy Efficiency in the Data Center1 IntroductionProcessing power in modern enterprises is continuallyincreasing. Increasing numbers of business processes arebeing supported by centralized information technology(IT). New improved applications and programme featuresrequire high-performance servers. In many cases, comprehensiveIT support for business procedures is mandatoryif you want to compete successfully in today’s globalmarkets. Today, the processing power installed in the datacenters of small and medium-sized enterprises equalsthat which, a few years ago, was only to be found in ahandful of major organizations. But this trend - which isessentially a positive one - is also responsible for the highelectric power consumption and cooling requirementsof today’s data centers. This presents new challengesfor those involved in the planning, implementation andoperation of IT infrastructures.• From the point of view of a company’s social responsibility,reducing its data center’s energy consumption -with the resulting positive effects for the environment– represents an investment in the future.This guide offers practical advice on the application ofmodern technologies in the planning, implementationand operation of data centers, in order to considerablyimprove their energy efficiency 1 whilst simultaneouslyreducing overall costs: experience has shown that it ispossible to achieve savings in a data center’s total costs(planning, construction, infrastructure, operation) of 20per cent or more. These guidelines apply to the planningof new data centers as well as to modernisation projectsfor existing infrastructures.Nowadays, the application of modern technologies makesit possible to drastically reduce a data center’s energyrequirements. This offers several advantages:•The data center’s operating costs are considerablyreduced. As operating costs account for a high proportionof total costs, any investment in improving a datacenter’s energy efficiency will often start to pay offafter only a few months.•A data center’s power and cooling capacity is oftenlimited by the existing infrastructure or by the powerprovider. In such cases, improving energy efficiencycan mean that these limits are never reached, thusobviating the need for additional high investmentcosts.5
