Dell PowerEdge R940 - Power, Thermal, and Acoustics; Power Consumption and Efficiency

Power, thermal, and acoustics
Power, thermal and acoustics
PowerEdge servers have an extensive collection of sensors that automatically track thermal activity, which helps regulate temperature
thereby reducing server noise and power consumption.

Feature Description
Power supply units (PSU) portfolio Dell’s PSU portfolio includes intelligent features such as dynamically
optimizing eciency while maintaining availability and redundancy.
Find additional information in the Power supply units section.
Tools for right-sizing Energy Smart Solution Advisor (ESSA) is a tool that can help you
determine the most ecient conguration 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 ecient PSU for your workload.

Energy Smart Data Center Assessment is a Dell Services oering
that uses infrastructure and thermal analysis to help maximize
system eciency. Learn more at Dell.com/EnergySmart.
Industry compliance Dell’s servers are compliant with all relevant industry certications
and guidelines, including 80 PLUS, Climate Savers, and ENERGY
STAR.
Power monitoring accuracy 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
Power capping 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 rst hardware vendor to leverage Intel
Node Manager for circuit- breaker fast capping.
