33 PowerEdge R620 Technical Guide8 Power, thermal and acousticsLower overall system-level power draw is a result of Dell’s breakthrough system design. The R620PowerEdge server maximizes performance per watt through a combination of power and cooling,energy efficient technologies, and tools. Additionally, the PowerEdge R620 has an extensivecollection of sensors that automatically track thermal activity, which helps regulate temperaturethereby 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 21 lists the tools and technologies Dell offers to help you achieve your data center goals bylowering power consumption and increasing energy efficiency.Table 21. Power tools and technologiesFeature DescriptionPower supply units (PSU)portfolioDell’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-sizingEnergy Smart Solution Advisor (ESSA) is a tool that helps you determine themost 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.
