8 Power, thermal and acoustics

Lower overall system-level power draw is a result of breakthrough system design. The PowerEdge
R220 server maximizes performance per watt through a combination of power and cooling, energy-
efficient technologies and tools. Additionally, the PowerEdge R220 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 12 outlines the tools and technologies Dell offers to help you achieve your data center goals
by lowering power consumption and increasing energy efficiency.

Power supply units

The R220 power supply subsystem consists of one non-redundant AC-DC 250W power supply AC-
DC power supply. Power cycling is enabled by a switch on the front of the chassis or controlled via
iDRAC7 with Lifecycle Controller.
The following power supply options are available for the R220:

Description
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
Dell.com/ESSA.
Dell PowerEdge servers are compliant with relevant industry certifications
and guidelines, including 80 PLUS. Additionally, the PowerEdge R220
server has earned ENERGY STAR
With the thermal design and reliability of Dell products, certain
configurations have the capability to operate at excursion-based
temperatures beyond the industry standard of 35°C (95°F) up to 45°C
(113°F) for excursionary periods of time and up to a 26°C dew point at 90%
relative humidity without impacting your availability model. Find additional
information at Dell.com/FreshAir.
