Power, Thermal And Acoustics; Power Consumption And Energy Efficiency - Dell PowerEdge R940 Technical Manual

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.

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.

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.
