  1. Liam NewcombeBCS Data Centre Specialist Group - Secretary Towards Low Carbon ICT Simulating the Financial and Environmental Costs of Operating a Data Centre

  2. Towards Low Carbon ICT Recognising the Problem IT Devices The Data Centre DCSG Data Centre Model Lessons Learned

  3. Towards Low Carbon ICT Recognising the Problem

  4. Recognising the Problem Two Kinds of Energy Use In Use Energy • Power Drawn by Device • Data Centre Overheads Embedded Energy • Manufacturing • Distribution • Packaging • Disposal

  5. Recognising the Problem Drivers for Green Computing • Initially about Financial Costs • Cheap IT kit against the Rising Cost of Power • Cost of M&E Exceeds Both • Counting the Cost of Carbon • EU ETS, Cap and Trade / Offset Cost • Corporate Social Responsibility / Brand Value • Choosing the ‘Lowest Cost’ Solution • Lowest overall cost = £ + £(CO2)

  6. Recognising the Problem - Technology Power Loss Chain Power Station – Data Centre

  7. Recognising the Problem - Technology Power Loss Chain Data Centre - Equipment

  8. Recognising the Problem - Technology Power Loss Chain Data Centre - Servers

  9. Recognising the Problem - Technology Power Loss Chain - Data Centre - CPU

  10. Recognising the Problem - Technology Power Loss Chain - Data Centre – CPU Used

  11. Recognising the Problem - Technology Power Loss Chain – Fossil Fuel – CPU Used

  12. Recognising the Problem - Programs What Programs Already Exist? • BCS Carbon Footprint Working Group • The Green Grid • EU Data Centre Code of Conduct • US Dept. of Energy / Energy Star • Too Many Others to List

  13. Recognising the Problem - Metrics

  14. Recognising the Problem Target Demand as well as Supply Existing Metrics • Target IT Department • Little Control • Sell Changes to the Business BCS Approach • Per Service Accounting • Target Demand • Compare Cost with Delivered Value

  15. Towards Low Carbon ICT IT Devices

  16. IT Devices Server Workloads

  17. IT Devices Server Power vs. Workload

  18. IT Devices Server Efficiency vs. Workload

  19. Towards Low Carbon ICT The Data Centre

  20. The Data Centre Data Centre Power - Where does it go?

  21. The Data Centre Fixed and Proportional Loads

  22. The Data Centre Put the Server in a Data Centre • What Power is Drawn at the Utility Feed?

  23. Towards Low Carbon ICT DCSG Data Centre Model A Holistic Approach to Data Centre Energy Efficiency

  24. DCSG Data Centre Model DCSG Model • Data Centre Power Transfer Function • Server Load to Power Function • IT Workload

  25. Current Commodity x86 Server Old Tier 4 Data Centre Nameplate Provisioning Rising Power Cost DCSG Data Centre Model Example Scenario

  26. DCSG Data Centre Model Old Tier 4 Data Centre, Nameplate Provisioning

  27. DCSG Data Centre Model Old Tier 4 Data Centre, Nameplate Provisioning

  28. New Load to Power Linear x86 Server Old Tier 4 Data Centre Nameplate Power Provisioning Rising Power Cost DCSG Data Centre Model Example Scenario

  29. DCSG Data Centre Model Old Tier 4 Data Centre, Nameplate Provisioning

  30. DCSG Data Centre Model Old Tier 4 Data Centre, Nameplate Provisioning

  31. New Load to Power Linear x86 Server New, Efficient Tier 3 Data Centre Peak Power Provisioning Rising Power Cost DCSG Data Centre Model Example Scenario

  32. DCSG Data Centre Model Efficient Data Centre, Peak Provisioning

  33. DCSG Data Centre Model Efficient Data Centre, Peak Provisioning

  34. Towards Low Carbon ICT Lessons Learned

  35. Lessons Learned What has our analysis told us about DC Operations? • Data Centres are not individual components, they are complex systems, view them as such • Component Improvements can be masked • Consider Merging your IT and M&E groups now

  36. Lessons Learned What has our analysis told us about DC Operations? • Buy servers by Performance / Watt not Performance / £ • One-App per server - buy the lowest power servers • Build lower Tier data centres and achieve reliability at the systems / network level • Build modular data centres to keep the utilisation levels high • Crop Rotate your data centre to sweep out the disused equipment

  37. Lessons Learned What has our analysis told us about Data Centres? • Energy Use and Cost are Correlated
