  2. Wattnode meters Campus Level power panel CRAC unit Data Center: 200 Level Flexim meters chilled water pipes Mechanical Room: 100 Level Main IT power feed (ATS4) server rack Raritan Power Distribution Units (PDUs) and Uninterruptible Power Supplies (UPSs)

  3. Documented Improvements • Verified server energy efficiency improvements from January 2010 to March 2011: Increased load shows overlap between old and replacement equipment, followed by decreases when old equipment has been removed • Successful experiment with replacement of 30 old servers with newer, presumably more efficient models led to funding of an ongoing annual $500K project to aggressively consolidate and virtualize most servers over the next three years, and to maintain a steady state three-year refresh cycle

  4. Compute Performance Estimated server compute performance has increased approximately 20% while energy demand has been reduced 5%

  5. Storage Energy OLD Storage NEW Storage • An enterprise storage refresh project also leveraged our newly green data center approach to (a) require the bidding vendors to document their energy efficiency as one of the selection criteria, and, (b) implement a new overhead cable distribution system to begin the (lengthy) process of removing under floor airflow blockages.

  6. Carbon Footprint Reduction • Server Consolidation and Storage Refresh Projects • 88 machines installed • 120 machines retired • Net decrease of 32 hardware devices

  7. CUIT’s Power Usage Effectiveness (PUE) 7/27/10 - Chilled Water Outage • Extensive instrumentation for real-time measurements of electrical and cooling loads has enabled us to measure and calculate our Power Usage Effectiveness in real time, and to confirm seasonal variations in PUE thanks to use of air- and water-side economizing

  8. CUIT’s Power Usage Effectiveness (PUE) 7/27/10 - Chilled Water Outage • Extensive instrumentation for real-time measurements of electrical and cooling loads has enabled us to measure and calculate our Power Usage Effectiveness in real time, and to confirm seasonal variations in PUE thanks to use of air- and water-side economizing

  9. CUIT’s Power Usage Effectiveness (PUE) • Seasonal variation identifies • summer and winter PUE • PUE varies by seasonal • variations and use of free • Winter free cooling • IT load steadily decreasing; • has little noticeable impact • on PUE
