  1. 1. Power Delivery in Today’s Data Center On-Demand Architecture for Network Critical Physical Infrastructure Kevin P. Burke, P.E. Critical Systems Manager – Southeast Region Kevin.Burke@schneider-electric.com 704-821-0524All content in this presentation is protected – © 2008 American Power Conversion Corporation
  2. 2. Agenda ● Present State of Affairs, Glimpse of the Future for Data Center Power Requirements. ● Efficiency Improvements and Path to Savings ● Higher Voltage Options for Data Center DistributionAPC by Schneider Electric
  3. 3. IT Changes and Mechanical/Electrical Load ImpactsAPC by Schneider Electric
  4. 4. High Density Computing 35 Per Rack Power Density (KW) 30 25 Max per-rack IT Load 20 15 Data Center rated 10 rack power capacity 5 0 Year IT Loads are greatly exceeding rated capacity!APC by Schneider Electric
  5. 5. Needs for the Future Now! ● Support for Higher Density Loads. ● High Density Zones ● kW per Rack vs Watts per Ft2 ● Higher Overall Building Efficiency. ● Improved Efficiency of Every Aspect of Data Center Power Consumption. ● Green Solutions. ● Reduced Environmental Impact ● Reduce – Recycle - Reuse ● Rapid Deployment and Relocation. ● Changing Face of Economy • Mergers & Acquisitions • Compaction, ConsolidationAPC by Schneider Electric
  6. 6. A standardized way to specify density Specifying DensityTraditional Same 500 kW data center – but different “averageway density” depending on how calculated: 746 watts/ft2 Ambiguous 179 watts/ft2 • Include access area around racks? • Include back-room area? 119 watts/ft2 • Consider total mains power consumption ? 189 watts/ft2White paper 120APC by Schneider Electric
  7. 7. A standardized way to specify density Specifying DensityTraditional Same 500 kW data center – but different “averageway density” depending on how calculated: 746 watts/ft2 Ambiguous 179 watts/ft2 • Include access area around racks? • Include back-room area? 119 watts/ft2 • Consider total mains power consumption ? 189 watts/ft2 A better way Total IT power 5 kW/rack = # of racks ● Eliminates the ambiguities of watts/ft2White paper ● Allows different densities for different areas 120 of the data centerAPC by Schneider Electric
  8. 8. 1 Spread the load Cooling strategies: 2 Supplemental cooling 3 High-density zone High-density zone 4 Whole room ● A “mini data center” with its own cooling ● Contributes no heat to ● Hot/cool air circulation localized within rest of data center the zone by short air paths and/or ● Works with existing containment room-based cooling ● Achieves optimal efficiencyAPC by Schneider Electric
  9. 9. High Efficiency UPS ● Most UPS Manufacturers are Striving for Higher Efficiencies in Standard Designs Today. ● On-Line UPS modules available with efficiencies as high as 96% at 100% Load. ● Flatter Efficiency Curves At Lighter Loads. ● More “Right Sized” Designs.APC by Schneider Electric
  10. 10. Efficiency Savings through Scalability ● Parallel for capacity or ● Parallel for capacity or redundancy redundancy ● 4000 amps system bus ● 4000 amps system bus ● 4 X 800 kVA/720 kW UPS ● 2 X 1600 kW Scalable UPS ● Average load of 40 – 60% ● Average load of 40 – 60% ● UPS load at 50-55% has ● UPS sized to ~ 80% of load Efficiency ranges from 91% with an efficiency of around to 94% 97% ● At a loading of 55%, a 2880 kW ● At a loading of 1600 kW (50% system (1600 kW load), with an system load), each module can be efficiency of 91% will have kW initially populated to 1000 kW. losses of 158 kW ● Each module, loaded to 80%, with ● At a kWh rate of $0.07, 158 kW of an efficiency of 97% will have losses translates to $96,886 per system kW losses of 49 kW. year ● At a kWh rate of $0.07, 49 kW of losses translates to $30,047 per year. 6 points of efficiency improvement saves $66,839 per year in electrical costsAPC by Schneider Electric

  12. 12. Typical North American Data Center Power Distribution Standard Configuration Utilizes PDUs to Transform UPS voltage to Server Power Supply Voltages  480 VAC, 3 Phase, 3 W + G to 208Y/120 VAC.  Overall Rating of PDUs Can be 1.5 to 3 Times the System Rating. Even the Best PDUs Have Efficiency Losses Associated With Them. Weight and Footprint Considerations in the Data Center White Space. Heat Losses Associated with XFMR 208Y/120 VAC. Five Conductors, A, B, C, N, G, Higher AmperageAPC by Schneider Electric
  13. 13. Typical 400 VAC Data Center Power Distribution 400 VAC Configuration Utilizes no PDUs to Transform UPS voltage to Server Power Supply Voltages  400Y/230 VAC, 3 Phase, 4 W + G to Rack.  Distribution More Closely Sized to the System Rating.  Single Autotransformer or 400 VAC UPS System can be used. Greatly Reduced Weight and Footprint Considerations in the Data Center White Space. No or Reduced XFMR Heat Losses 400Y/230 VAC. Five Conductors, A, B, C, N, G, Lower AmperageAPC by Schneider Electric
