Dell EMC PowerEdge R740 - 8 Power, Thermal, and Acoustics; Power Consumption and Energy Efficiency

Power, Thermal, and Acoustics
The lower overall system-level power draw is a result of the breakthrough system design developed by Dell EMC. The system aims to
maximize performance-per-watt through a combination of energy ecient technologies, optimized thermal designs and intelligent fan
control algorithms. System fan control algorithms use an extensive array of sensors that automatically monitor power and thermal activity
to minimize fan speeds based on system cooling requirements, reducing the power required for cooling.

Power consumption and energy eciency
With the rise in the cost of energy coupled with increasing data center density, Dell EMC provides tools and technologies to help you realize
greater performance with lower energy cost and wastage. More ecient data center usage can reduce costs by slowing the need for
additional data center space. The following table lists the tools and technologies that Dell EMC oers to help you achieve your data center
goals by lowering power consumption and increasing energy eciency.

Feature Description
Power supply units (PSU) portfolio Dell EMC PSU portfolio includes intelligent features such as
dynamically optimizing eciency while maintaining availability and
redundancy. For more information, see, the Power supply units
section.
Tools for right-sizing The Dell Enterprise Infrastructure Planning Tool (EIPT) is a tool that
helps you plan and tune your computer and infrastructure
equipment for maximum eciency by calculating hardware power
consumption, power infrastructure and storage. Learn more at
Dell.com/calc.
Power monitoring accuracy PSU power monitoring improvements include:
• Power monitoring accuracy of 1%, whereas the industry
standard is 5%
• More accurate reporting of power
• Better performance under a power cap
Power capping Use Dell EMC systems management to set the power cap limit for
your systems to limit the output of a PSU and reduce system power
consumption. Dell EMC is the rst hardware vendor to leverage
Intel Node Manager for circuit-breaker fast capping.
