8 Power, thermal and acoustics

Lower overall system-level power draw is a result of Dell's breakthrough system design. PowerEdge
servers aim to maximize performance-per-watt through a combination of energy efficient
technologies, optimized thermal designs and intelligent fan control algorithms. The PowerEdge
R730/R730xd fan control algorithms use an extensive array of sensors that automatically monitor
power and thermal activity to minimize fan speeds based on system cooling requirements, reducing
the power required for cooling.

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 21 lists the tools and technologies Dell offers to help you achieve your data center goals by
lowering power consumption and increasing energy efficiency.

Description
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.
Energy Smart Solution Advisor (ESSA) is a tool that helps IT professionals plan
and tune their computer and infrastructure equipment for maximum efficiency
by calculating the hardware power consumption, power infrastructure and
storage. Learn more at Dell.com/calc.
Dell's servers are compliant with all relevant industry certifications and
guidelines, including 80 PLUS, Climate Savers and
PSU 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
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.
iDRAC8 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.
With the thermal design and reliability of Dell products, certain configurations
th
of Dell 13 generation servers have the capability to operate at temperatures
beyond the industry standard of 35°C (95°F). The supported configurations that
meet Dell Fresh Air 2.0 specifications can operate continuously at 40°C (104°F)
and up to 45°C (113°F) for excursionary periods of time and up to a 29°C dew
point at 90% relative humidity without impacting your availability model. Find
