26 PowerEdge M520 Technical Guide

8 Power, thermal, and acoustics

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

PowerEdge M520 blade server and M1000e chassis enclosure maximize performance per watt

through a combination of power and cooling, energy efficient technologies and tools. Additionally,

the M520 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 data center space.

Table 14 lists the tools and technologies Dell offers to help you achieve your data center goals by

lowering power consumption and increasing energy efficiency.

Description

Power supply units (PSU)

portfolio

Dell’s PSU portfolio includes intelligent features such as dynamically

optimizing efficiency while maintaining availability and redundancy.

Tools for right-sizing

Energy Smart Solution Advisor (ESSA) is a tool that helps 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. Learn more at Dell.com/ESSA.

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.

Active power management

Intel Node Manager is an embedded technology that provides individual

server-level power reporting and power limiting functionality. Dell offers a
