20 Why Are Metrics Important? Awareness If you can t measure it, you can t improve it Benchmarking Improving operations continuous improvement Comparing across the industry company to company Improvement over time generation to generation Technology validate claims Resulting in Better efficiency Better total cost of ownership

21 Why DCP? DCiE works well for assisting in optimizing power consumption of infrastructure equipment To address both infrastructure and IT productivity needs, we need one or more metrics to complement PUE/DCiE Infrastructure Equipment IT Equipment PUE/DCiE DCP

22 Data Center Productivity What is Data Center Productivity (DCP)? Methodology for quantifying the useful work that a data center produces relative to the quantity of any resource that it consumes to produce this work Mathematically expressed: DCP = Useful Work Produced by Data Center Resource Consumed Producing the Work Useful work is defined as completed tasks that have value to the end user or business supported by the data center 22

23 Baseline Efficiency Market Study Study Overview Interviewed data center facility operators and IT managers via phone Questions focused on drivers for and obstacles to energy efficiency in the data center Data Centers Profiled: 25 23

24 Baseline Efficiency Market Study Study Findings Drivers for Action The strongest motivation for increasing energy efficiency in data centers is to relieve constraints on increased IT capacity Interest in environmental sustainability at a corporate level is a driver for more efficient management of data centers Obstacles to Action Risk aversion and fear of downtime is slowing adoption of best practices (e.g., as enabling server power management features) IT professionals don t typically have strong incentives to invest in reducing energy consumption beyond the extent to which it lets them install more equipment 24

25 Baseline Efficiency Market Study Study Findings (continued) Positive Trends The Green Grid s first Data Center metrics, PUE and DCiE, are in use and gaining recognition Virtualization is a broadly-implemented strategy for improving energy efficiency Opportunities Data center managers want industry-standard instrumentation and tools for monitoring, trend analysis & capacity planning and benchmarking Data center energy management is an area of new expertise and opportunity for data center professionals 25

26 Addressing Organizational Barriers to Managing Efficiency 26 Organizational Challenges Many businesses operate independent IT and Facilities departments which are motivated by different goals/interests IT typically buys IT equipment while Facilities foots the energy bill Data center energy consumption is often ignored and not included in the TCO calculations IT refresh cycles are 2-5 years with rising power and cooling loads while Facilities are designed for years There are a number of external influences as well including legislation, sustainability initiatives, availability and cost of energy M Data Center Power Meters M M M M M M M M M M M M M M M M M M M M M M M M M M Utility Meter M Facility Meters M IT Meters

27 Addressing Organizational Barriers to Managing Efficiency Recommendations Energy efficiency needs to be driven from the CEO down in an organization Need to integrate independent monitoring systems (IT, Facilities, Utilities) into actionable knowledge Goals and incentives need to be aligned between IT and Facilities to optimize energy efficiency while meeting the business objectives Design team, operations and supply chain include energy efficiency in TCO calculations Utilize energy efficient IT and Facility components and systems to measure, monitor and provide auditable data for corporate sustainability initiatives Incorporate The Green Grid processes 27
