22 PowerEdge C5220 Technical Guide

7 Power

Lower overall system-level power draw is a result of Dell’s breakthrough system design. PowerEdge

servers maximize performance per watt through a combination of power and cooling, energy

efficient technologies, and tools. Additionally, PowerEdge servers have 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 data center space.

Table 13 lists the tools and technologies Dell offers to help you achieve your data center goals by

lowering power consumption and increasing energy efficiency.

Description

Tools for right-sizing

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 power supply Advisor can help you choose the

best, most efficient power supply 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

Power supply 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’s systems management to set the power cap limit for your systems

to limit the output of a power supply and reduce system power

consumption. Dell is the first hardware vendor to leverage Intel Node

Manager for circuit-breaker fast capping.

Active power management

Intel Node Manager is an embedded technology that provides individual

server-level power reporting and power limiting functionality.

Thermal control of fan speed optimizes the thermal settings for your

environment to reduce fan consumption and lower system power

consumption.

Idle power enables Dell servers to run as efficiently when idle as when at full

workload.
