Today’s data center is changing rapidly. Many enterprises
are integrating new technology solutions to modernize and
evolve their organizations. Most are pursuing a path to ensure
appropriate levels of IT service delivery and cost efficiency
and alignment to business goals. For some data centers this
means providing state of the art levels of availability, flexibility,
and scalability, while for others the goal may be to provide
“sufficient” levels of services while keeping new capital
expenditures to a minimum.
Either way, data centers can be placed on a spectrum of
efficiency and flexibility. IBM and IDC have developed a
data center operational efficiency model for assessing the
capability levels of today’s data center and describing the ways
IT organizations can progress along the path of data center
transformation. There are four key stages that describe the
typical evolution of a data center as it relates to efficiency:
Basic, Consolidated, Available and Strategic.

  2. 2. ii Data center operational efficiency best practices Data center operational efficiency best practices: Enabling increased new project spending by improving data center efficiency is an IBM study that developed a data center operational efficiency model for assessing the capability levels of today’s data center and describes the ways IT organizations can progress along the path of data center transformation. The report was written by IDC, which also executed the survey and interviews on behalf of IBM. The authors would like to give special thanks to the following individuals for their assistance and support in developing this report: ● Dr. Ian Stewart, Director of Advanced Computing, University of Bristol ● Antonio Buratti, CIO, ABI (Associazione Bancaria Italiana) ● Pierre Debagnard, General Manager of Albiant-IT, BPCE Group ● Xiao Xiao Bin, IT Manager, INESA Information Solution Group Co.

  18. 18. 14 Data center operational efficiency best practicesMoving toward a Strategic data center How IBM can helpData centers are under constant pressure to scale and evolve IBM helps enterprises around the world plan, optimizeto meet the changing needs of the underlying business. To and automate their data centers in order to support theiradapt to these challenges, each data center takes a slightly business growth and objectives. IBM has a broad portfoliodifferent approach. of data center facilities planning and design, cloud, IT virtualization, network modernization, business resilienceToday, about one in five data centers operate at the Strategic, and automation services that can help you meet your dataor highest efficiency, level. Companies not yet operating at center efficiency objectives.this level can achieve greater efficiency by emulating thefour key behaviors of IT organizations that operate Strategic You can get started on your data center efficiency journeydata centers: by taking the Data Center Efficiency Self-Assessment. This no-cost online tool will give you a quick snapshot of your● Optimize the server, storage, network and facilities assets to efficiency status across facilities management, servers, storage maximize capacity and availability and networks.● Design for flexibility to support changing business needs● Use automation tools to improve service levels For more information and availability To learn more about how IBM can help you progress on your● Have a plan that aligns with the business goals and keep journey to greater data center efficiency, you can contact your it current. IBM representative or visit the following websites:For most companies, getting there will not happen overnight. typically takes organizations several years of planning andstrategic investments in each area of the data center to achieve status. While North American organizations andcompanies with more than 500 employees had the highestproportion of Strategic data centers, this level of efficiency isachievable for any company. Strategic data centers were foundin all regions of the world and in smaller companies.Most companies, whatever their size, plan on using outsidehelp with the projects that advance efficiency, a realizationespecially shared by Strategic data centers. To achieve thehighest levels of efficiency, data centers must continuallyre-evaluate their performance, reviewing their investments intools, technologies and governance, and must have the rightlevel of skills and assistance. Doing so can yield benefits ingreater staffing efficiencies, greater levels of flexibility and theability to spend more time on strategic IT initiative to supportthe business.
  19. 19. IBM Global Data Center Study 15 and outsourcing). Respondents were recruited by phone to complete the survey over the Internet. Both phone and web Study methodology portions of the survey were administered in the local language. The information for this white paper came from a global survey of 308 IT executives, conducted in January 2012, and was The surveys asked respondents to provide information about supplemented by in-depth interviews with data center managers their data center, tools, technologies and processes across eight representing each stage of data center efficiency. The survey separate areas: data center operations, facilities management, population consisted of IT executives who have responsibility servers, storage, network, applications and tools, governance for or influence over their organization’s data center strategy, and staffing. The questions were designed to unearth the data from organizations of over $50 million in revenue with at least center’s efficiency level in each of these areas. The data from one enterprise-class data center. Respondents were randomly the survey was imported into an IDC model designed to assess recruited and screened from international panels and came from and categorize efficiency in each of these areas and to roll it seven different countries: the United States, Brazil, Canada, up into an overall data center efficiency rating (Figure 7). The China, Germany, France, and India. Global data was derived by model examines the levers by which data centers can improve weighting IT spending on server systems, storage, enterprise their infrastructure and identified a number of areas, including networks, packaged software and services (excluding telecom availability/resilience, cost-effectiveness and the flexibility to provide the capacity needed by the business. The demographics of the respondents were: 32% 30% • 60 percent from mature countries and 40 percent in growth markets • 63 percent from large enterprise and 37 percent from small and mid-sized businesses% of survey respondents 21% • 83 percent were IT managers and 17 percent were chief information officers 17% • 25 industries covering finance, communications, industrial, distribution, public sector and others. The information from the survey was supplemented with five in-depth interviews with executives responsible for data centers 1 standard 1 standard in North America, Europe and Asia. The respondents had deviation deviation responsibility for full data center operations and represented the full spectrum of data center efficiency stages.
