Data Center Energy Efficiency Challenges 1. Technology Scalability Each DC is unique (business requirements, IT components, facilities etc.) 1. Energy Efficiency Metrics DCIE - Metric (Data Center Infrastructure Efficiency = total energy usage / IT energy consumption) can be problematic Fall Winter Spring 1. Reliability vs. Energy Efficiency Energy efficiency improvements have to be manageable without compromising reliability of the operation 1. Integration Integration has to include the underlying IT technology, energy and thermal management, power delivery technologies as well as cooling and facilities
Where does all the Energy go? 100 Units Data center Server hardware Processor Server loads TYPICAL USAGE RATES Mainframe UNIX Wintel 80 100% 10 20% 5 12% HVAC, UPS 55% 35 Units IT Power 45% 33 Units Delivered* Performance, Capacity/ Watt Other 70% Processor Up to 95% idle resource 30% (Power supply, fans, memory, Resources used at 5-20% average for appl. load VMware study of over 300,000 servers showed that over 20% of the x86 servers are running below 0.5% utilization with nearly 75% running below 5% utilization. End to End Initiatives *Data source: U.S. Department of Energy May 18, 2007 Reduce cooling/ups needs vs. energy going in servers, capture heat at source (Potential gain 10%) More efficient cooling and energy supply Higher efficiency infrastructure, power management' ( > 3yrs older is good target ) Better server hardware design Reduce consumption @ chip level ( Cap power usage ) Advanced processor design + process Reduce idle/unused capacity which still consumes energy (Utilization 5 to 20 % gain) Enhance resource usage rate (consolidation/ virtualization) 1 watt of application computing requires 30+ watts of power
