26 PowerEdge R320 Technical Guide8 Power, thermal and acousticsLower overall system-level power draw is a result of breakthrough system design. The DellPowerEdge R320 server maximizes performance per watt through a combination of power andcooling, energy-efficient technologies, and tools. Additionally, the PowerEdge R320 has anextensive collection of sensors that automatically track thermal activity, which helps regulatetemperature thereby reducing server noise and power consumption.Power consumption and energy efficiencyWith the rise in the cost of energy coupled with increasing data center density, Dell provides toolsand technologies to help you realize greater performance with less energy cost and waste. Moreefficient data center usage can reduce costs by slowing the need for additional center space.Table 16 lists the tools and technologies Dell offers to help you achieve your data center goals bylowering power consumption and increasing energy efficiency.Table 16. Power tools and technologiesFeature DescriptionPower supply unit (PSU)portfolio(hot-plug PSU only)Dell’s PSU portfolio includes intelligent features such as dynamicallyoptimizing efficiency while maintaining availability and redundancy. Findadditional information in the Power supply units section.Tools for right-sizingDell Energy Smart Solution Advisor (ESSA) is a tool that helps you determinethe most efficient configuration possible. With ESSA, you can calculate thepower consumption of your hardware, power infrastructure and storage.ESSA can help you determine exactly how much power your server will useat a given workload, and the PSU Advisor can help you choose the best,most efficient PSU for your workload. Learn more at Dell.com/ESSA.Industry complianceDell PowerEdge servers are compliant with relevant industry certificationsand guidelines, including 80 PLUS. Additionally, the Dell PowerEdge R320server has earned the ENERGY STAR® 1.0 Server designation.Power monitoringaccuracy(hot-plug PSU only)PSU power monitoring improvements include: Dell’s power monitoring accuracy is currently 1%, whereas the industrystandard is 5% More accurate reporting of power Better performance under a power capPower capping(hot-plug PSU only)Use Dell’s systems management to set the power cap limit for your systemsto limit the output of a PSU and reduce system power consumption. Dell isthe first hardware vendor to leverage Intel Node Manager forcircuit-breaker fast capping.Systems management(hot-plug PSU only)iDRAC7 Enterprise provides server-level management that monitors,reports, and controls power consumption at the processor, memory andsystem level.Dell OpenManage Power Center delivers group power management at therack, row and data center level for servers, power distribution units anduninterruptible power supplies.
