The Green Grid in 2009: Helping Industry Move Forward

Why Create Metrics? Awareness o “If you can’t measure it, you can’t improve it” Benchmarking o Continuous improvement of operations o Comparing across the industry o Improvement over time/generation to generation o Validate claims Consistency o Common Vocabulary o Industry & Government Collaboration o Better Efficiency

PUE/DCiE: The Green Grid Metrics For Facilities Total Facility Power IT Equipment Power PUE = Power Switchgea r UPS Battery Backup etc. Cooling Chillers CRACs etc. IT Equipment Servers Storage Telco etc. PUE & DCiE For Efficient Facilities DCP For The Work You Do Total Facility Power Total Facility Power IT Equipment Power DCiE = X 100% What % of facility power is delivered to my IT equipment? How efficient is my facility in delivering power to IT equipment? IT Equipment Power

PUE and DCiE: Do/Do Not PUE and DCiE Do: PUE and DCiE Do Not: Provide information on how effective the energy is being used by the IT equipment in a facility Provide a good picture of efficiency when used consistently over time Provide a starting point to determine the effectiveness of energy use in a data center Address emerging models such as containers Address the kinds of energy sources that the facility uses Adequately help an organization if measurements taken on a one- time basis Serve as the final word on efficiency Address productivity

Sample Data Center: PUE Impact Assumptions 5 Mw IT load $0.10/kW-hr 7x24 operation Sample data center: PUE Mw purchase from utility $8.8 million annual power bill Best in class: PUE Mw purchase from utility $6.1 million annual power bill Net Savings of $2.7 Million Annually Through Increased Efficiency

New PUE/DCiE Reporting Guidelines Total Facility Power IT Equipment Power PUE = What were the environmental conditions? When were measurements taken? Where were measurements taken? How often were measurements taken? Total Facility Power IT Equipment Power DCiE = X 100% What % of facility power is delivered to my IT equipment? How efficient is my facility in delivering power to IT equipment? How to compare results?

Measurement Accuracy Reporting (from DCiE Detailed Analysis WP)‏

Examples of Reported Results ‘M’ = monthly ‘W’ = weekly ‘D’ = daily ‘C’ = continuously (frequency one hour or less)‏

Classification of Publicly- Reported Metrics Results

Intended Results of Reporting Guidelines Consistent, apples-to-apples reporting Identify and Promote exceptional results Quality Assurance Drive greater industry adoption

DCP: Under Development Power Switchgear UPS Battery Backup etc. Cooling Chillers CRACs etc. IT Equipment Servers Storage Telco etc. PUE & DCiE For Efficient Facilities DCP For The Work You Do Total Facility Power Useful Work Total Facility Power DCP = How Much Work Can My IT Equipment Do, In My Facility? IT Equipment Power

Productivity Proposals Proxy NameDescription Useful Work Self-Assessment and Reporting All applications self-report, utility function is uniform and equal to one; user must decide how to normalize each task DCeP Subset by Productivity LinkA subset of all applications self-report using Productivity Link, a freely available Software Development Kit (SDK); scale results to represent whole data center DCeP Subset by Sample WorkloadAn instrumented subset of servers is measured running as sample workload; scale results to represent whole data center Bits per Kilowatt-hourSum all outbound bitstreams from data center, divide by energy used by data center Weighted CPU Utilization – SPECint_rate Use CPU clock speed, SPECint_rate benchmarks, and CPU utilization to determine amount of work being done. Weighted CPU Utilization – SPECpower Use CPU clock speed, SPECpower benchmarks, and CPU utilization to determine amount of work being done. Compute Units Per Second (CUPS)Uses trend curve based on Moore's law, age of server, and CPU utilization to determine work done. Operating System Workload Efficiency Estimate efficiency by calculating the number of operating system instances per watt

DCP: Productivity Proxies Goal is to move the discussion forward The Green Grid is gathering feedback on proxy proposals from members and industry Best prospects will be selected for further study 8 Proxies are proposed

The Green Grid Productivity Indicator Simple, quick visualization of how resources are being targeted versus used Radial graph for relevant indicators such as: o data center efficiency, o data center utilization o IT utilization
