28 PowerEdge R820 Technical Guide

Lower overall system-level power draw is a result of breakthrough system design. The Dell

PowerEdge R820 server maximizes performance per watt through a combination of power and

cooling, energy efficient technologies, and tools. Additionally, the PowerEdge R820 has an extensive

collection of sensors that automatically track thermal activity, which helps regulate temperature

thereby reducing server noise and power consumption.

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 18 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 units (PSU)

portfolio

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 Dell.com/calc.

Energy Smart Data Center Assessment is a Dell Services offering that uses

infrastructure and thermal analysis to help maximize system efficiency. Learn

more at Dell.com/EnergySmart.

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

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 first hardware vendor to leverage Intel Node Manager for

circuit-breaker fast capping.

Systems management

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.
