Enhancing Data Center Efficiency Through Effective Benchmarking Practices

This presentation explores the importance of benchmarking in identifying best practices within data centers. It highlights key metrics, such as the ratio of IT equipment power to total power, revealing insights on overall efficiency. With an average IT equipment load density of 0.49 and HVAC system effectiveness averaging 1.68, the data underscores significant variances in energy utilization. By analyzing top-performing systems, organizations can optimize their operations and achieve substantial savings. Leveraging data from LBNL benchmarking, this discussion aims to equip professionals with the knowledge to improve efficiency in data centers.

  1. Benchmarking<Presenter>

  2. Benchmark Results Can Help Identify Best Practices The ratio of IT equipment power to the total is an indicator of relative overall efficiency. Examination of individual systems and components in the centers that performed well helped to identify best practices.

  3. IT Equipment Load Density

  4. Percentage of Power to IT Equipment Average 0.49

  5. HVAC System Effectiveness Average 1.68

  6. High Level Metric— Ratio of Electricity Delivered to IT Equipment Average .57 Higher is better Source: LBNL Benchmarking

  7. Alternate High Level Metric – Data Center Total / IT Equipment (PUE) Average 1.83 Lower is better Source: LBNL Benchmarking

  8. Change in LBNL’s supercomputer center

  9. Performance varies The relative percentages of the energy actually doing computing varied considerably.

  10. Energy use in Data Centers (LBNL/PG&E)

  11. UPS Draft Labeling Standard • Based upon proposed European Standard • Possible use in incentive programs

  12. Measured power supply efficiency

  13. Take Aways • Various meanings for “data centers” • Benchmarking helps identify performance • Benchmarking suggests best practices • Efficiency varies • Large opportunity for savings • Resources are available
