Dell PowerEdge R720 Technical Guide - Page 34

Lower overall system-level power draw is a result of Dell's breakthrough system design. PowerEdge servers maximize performance per watt through a combination of power and cooling, energy efficient technologies, and tools. Additionally, PowerEdge servers have an extensive collection of sensors that automatically track thermal activity, which helps regulate temperature thereby reducing server noise and power consumption. With the rise in the cost of energy coupled with increasing data center density, Dell provides tools and technologies to help you realize greater performance with less energy cost and waste. More efficient data center usage can reduce costs by slowing the need for additional data center space. Table 19 lists the tools and technologies Dell offers to help you achieve your data center goals by lowering power consumption and increasing energy efficiency. Feature Power supply units (PSU) portfolio Tools for right-sizing Industry compliance Power monitoring accuracy Power capping Systems management Description Dell's PSU portfolio includes intelligent features such as dynamically optimizing efficiency while maintaining availability and redundancy. Find additional information in the Power supply units section. Energy Smart Solution Advisor (ESSA) is a tool that can help you determine the most efficient configuration possible. With Dell's ESSA, you can calculate the power consumption of your hardware, power infrastructure, and storage. ESSA can help you determine exactly how much power your server will use at a given workload, and the PSU Advisor can help you choose the best, most efficient PSU for your workload.

Learn more at Dell.com/EnergySmart. Dell's servers are compliant with all relevant industry certifications and guidelines, including 80 PLUS, Climate Savers, and ENERGY STAR®. PSU power monitoring improvements include:  Dell's power monitoring accuracy is currently 1%, whereas the industry standard is 5%  More accurate reporting of power  Better performance under a power cap Use Dell's systems management to set the power cap limit for your systems to limit the output of a PSU and reduce system power consumption. Dell is the first hardware vendor to leverage Intel® Node Manager for circuit-breaker fast capping. iDRAC7 Enterprise provides server-level management that monitors, reports, and controls power consumption at the processor, memory, and system level. Dell OpenManage™ Power Center delivers group power management at the rack, row, and data center level for servers, power distribution units, and uninterruptible power supplies. 34 PowerEdge R720 and R720xd Technical Guide
