Estado actual y proyecciones futuras de PUE/DCiE

  1. 1. Power Usage Effectiveness (PUE) Status & Directions Kathrin Winkler Director, The Green Grid VP, EMC Corporation
  2. 2. About The Green Grid • A not-for-profit global consortium focused on driving energy efficiency in the computing ecosystem • Developing meaningful and user-centric metrics to help IT and Facilities better manage their computing resources • Developing and promoting standards, measurement methods, best practices and technologies that support these metrics 2 2 Copyright © 2010, The Green Grid
  3. 3. Why Create Metrics? Awareness Benchmarking Consistency • “If you can’t • Continuous • Common measure it, you improvement of Vocabulary can’t improve it” operations • Industry & • Finding the hot • Comparing across Government spots the industry Collaboration • Improvement • Better Efficiency over time/ generation to generation • Validate claims 3 3 Copyright © 2010, The Green Grid
  4. 4. Impact of IT Power Consumption Computer Room Air Conditioner power Server, network and storage consumption power consumption 23% - 54% 38% - 63% Battery Backup power consumption 6% - 13% Lighting power consumption 1% - 2% Server Power Consumption Impacts Power throughout the Datacenter 4 Copyright © 2010, The Green Grid
  5. 5. Data Center Power Efficiency Metrics: PUE and DCiE Total Facility Power PUE = Power Usage Effectiveness = IT Equipment Power Data Center 1 IT Equipment Power DCiE = = = Infrastructure Efficiency PUE Total Facility Power 5 Copyright © 2010, The Green Grid
  6. 6. PUE Refined Total Facility Power or Energy PUE = IT Equipment Power or Energy Point of Measurement Frequency of Measurement Duration of Measurement 6 Copyright © 2010, The Green (DCiE) Detailed Analysis (white paper #14) 60 Sources: The Green Grid Metrics: Data Center Infrastructure EfficiencyGrid Usage and Public Reporting Guidelines for The Green Grid's Infrastructure Metrics PUE/DCiE (white paper #22)
  7. 7. PUE clarifications • PUEs of < 1.0 and DCiEs of > 1.0 are *not* allowed • These elements are always ≥ 0 – Power consumed by IT equipment – Power lost in distribution – Power consumed by cooling equipment • PUE measures use within the data center, and does not include – Re-use of waste heat – Distributed power generation 7 Copyright © 2010, The Green Grid
  8. 8. PUE Nomenclature Official PUE reports provide these information with subscripts appended to the metric PUEx,y or DCiEx,y x = Precision level of measurement (L1, L2, L3) y = Timeframe and collection frequency: D = Daily W = Weekly M = Monthly Y = Yearly C = Continuously 8 Copyright © 2010, The Green Grid
  9. 9. Reporting Precision Level 1 Level 2 Level 3 (Basic) (Intermediate) (Advanced) Server, Storage IT Equipment Power UPS PDU device, Router, Measurement From… etc. Data Center input less Data Center Total Facility Power Data Center shared HVAC input less Measurement From… input power plus building shared HVAC lighting, security, etc. Minimum Monthly/ Daily Continuous Measurement Interval Weekly 9 Copyright © 2010, The Green Grid
  10. 10. Example Reported Results Single DCiE measurement (0.45) taken using a Level 1 meter 0.45 DCiEL1,-- placement Yearly average DCiE (0.51), using data points gathered monthly 0.51 DCiEL1,YM with a Level 1 meter placement Monthly average PUE (1.6) using data points gathered weekly with 1.6 PUEL1,MW a Level 1 meter placement Weekly average DCiE (0.43), using data points gathered daily with a 0.43DCiEL1,WD Level 1 meter placement Weekly average PUE using data points gathered continuously with 1.8 PUEL2,WC a Level 2 meter placement. Yearly average PUE (2.1) using continuous measurements with a 2.1 PUEL3,YC Level 3 meter placement. 10 Copyright © 2010, The Green Grid
  11. 11. Classes of Measurement ResultsClass Description Benefit to Reporting Organization Unrecognized A publicly reported result with no claims of following TGG’s guidelines. TGG will not comment on unrecognized results. Reported A publicly reported result by the Reporting organization can reporting organization claiming they use standard materials from followed TGG’s measurement The Green Grid to explain recommendations and nomenclature process and results to guidelines. TGG will not comment on audience. Reported results. Registered A publicly reported result, with key Official registration of report contextual data provided to TGG reported result. Receipt of a by the reporting organization to TGG’s registration number from TGG. data center performance database. Link to public report data from TGG’s website. Certified A publicly reported result, with key All benefits applicable to additional data required for third-party registered results, plus, validation or certification of results, consideration of reported provided to TGG by the reporting results in future TGG award or organization. recognition programs. 11 Copyright © 2010, The Green Grid

  13. 13. PUE Scalability Metric 13 Copyright © 2010, The Green Grid
  14. 14. Partial PUE Definition • PUE = Total Facility Power divided by the IT Equipment Power • This takes into account power use within a facility • Partial PUE is for power use within a boundary • So: pPUE = Total Power within a boundary divided by the IT Equipment Power within that boundary 14 Copyright © 2010, The Green Grid
  15. 15. pPUE Example 121 kW Transformer Container 6 kW 115 kW UPS 5 kW 100 kW 95 kW IT Equipment 15 kW Chiller 30 tons Cooling • PUE = 121/95 = 1.27 • pPUE of Container = 100/95 = 1.05 15 Copyright © 2010, The Green Grid 15
  16. 16. Energy Reuse Factor rejected Non-DC space H Cool G Absorp Chiller A E I Utility F ICT B UPS C PDU D Data Center A+B A + B- F Boundary PUE = ERF= D D Both PUE & ERF valid metrics 16 Copyright © 2010, The Green Grid
  17. 17. TGG Metrics How efficient is my facility in Total Facility Power delivering power to IT PUE = IT Equipment Power equipment? What % of facility power is IT Equipment Power delivered to my IT DCiE = Total Facility Power x 100% equipment? How Much Work Can My IT Useful Work Equipment Do, In My Facility? DCP= Total Facility Power Copyright © 2010, The Green Grid
  18. 18. Data Center Energy Productivity • Data Center Energy Productivity (DCeP) • First attempt to define useful work metric • Very comprehensive, very accurate • However, difficult to measure • Some terms require user interpretation – eg., Ui(t,T) is the utility (value) of a transaction – Subjective, could be different for each organization 18 Copyright © 2010, The Green Grid
  19. 19. Alternative Proposal - Proxies • Proxies indicate how much work is being done without measuring work directly Should be highly correlated to useful work Should be easier, cheaper, faster to collect • Proxies are often used where complex measures would be impractical eg., EPA Miles Per Gallon, marketing focus group, Dow Jones Industrial Average, or CNN Audience Reaction Meter 19 Copyright © 2010, The Green Grid
  20. 20. Proxy Proposals 1. DCeP-based Proxies • Simplified DCeP • Productivity Link • Sample workload 2. Bits per kWH 3. CPU-based proxies • SPECint_rate • SPECpower • CUPS 4. OS images per Watt 20 Copyright © 2010, The Green Grid
  21. 21. Proxy Shortcomings In general, the proxy proposals: • Aren’t meant for comparison between data centers Useful for tracking progress within a data center over time No guidelines for use and reporting, so wide variation possible • Don’t address all data center devices equally Proposals tend to be server-centric Storage, networking, telephony, appliances, co-processors, etc • Don’t consider the value of stored data • Don’t account for interaction between devices 21 Copyright © 2010, The Green Grid
  22. 22. Where to Next? • Proxies • Currently testing IT Productivity Proxies with the US National Labs • Using instrumented applications as a control • Starting with the Intel Energy Checker SDK as a basis for instrumenting applications within the Data Center Design Guide effort • Sharing results with other organizations globally 22 Copyright © 2010, The Green Grid
  23. 23. Metric Harmonization Efforts • Global Metric Harmonization Ministry of Economy, Trade and Industry (METI) Green IT Promotional Council (GIPC) The U.S. Department of Energy (DOE) The U.S. Environmental Protection Agency (EPA) The European Union (EU) The Green Grid (TGG) • US Industry Consensus Session Environmental Protection Agency (EPA) Department of Energy (DOE) 7x24 Exchange American Socienty of Heating, Refrigerating and Air-conditioning Engineers (ASHRAE) Silicon Valley Leadership Group (SVLG) The Green Grid (TGG) Uptime Institute United States Green Building Council (USGBC) 23 Copyright © 2010, The Green Grid
  24. 24. Possible New PUE Variations • M&M WG has an approved AR to review and identify if we will proceed with any further possible variations of PUE • PUE Estimated • PUE Calculated • Design PUE • Design Day PUE • Virtual PUE • …. 24 Copyright © 2010, The Green Grid
