Power, thermal, and acoustics
Lower overall system-level power draw is a result of breakthrough system design. The Dell
PowerEdge R420 server maximizes performance per watt through a combination of power and
cooling, energy efficient technologies, and tools. Additionally, the PowerEdge R420 has an extensive
collection of sensors that automatically track thermal activity, which helps regulate temperature
thereby reducing server noise and power consumption.
Power consumption and energy efficiency
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 center space.
Table 16 lists the tools and technologies Dell offers to help you achieve your data center goals by
lowering power consumption and increasing energy efficiency.

Feature
Description
Power supply unit (PSU)
portfolio
(redundant PSU only)
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.
Tools for right-sizing
Dell Energy Smart Solution Advisor (ESSA)
is a tool that helps you determine
the most efficient configuration possible. With 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

Industry compliance
Dell’s servers are compliant with all relevant industry certifications and
guidelines, including 80 PLUS, Climate Savers, and
ENERGY STAR.
Power monitoring
accuracy
(hot- plug PSU only)
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
(hot- plug PSU only)
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.
Systems management
(redundant PSU only)
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.
