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.

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 
Dell.com/ESSA. 
The PowerEdge C6220 II server is compliant with all relevant industry 
certifications and guidelines, including 80 PLUS.  
Power monitoring 
accuracy 
Power supply power monitoring improvements include:  
  Dell power monitoring accuracy is currently 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 power supply and reduce system power 
consumption. Dell is the first hardware vendor to leverage Intel Node 
Manager for circuit-breaker fast capping. 
With the thermal design and reliability of Dell products, you can have the 
capability to operate at excursion-based temperatures beyond the industry 
standard of 35°C (95°F) without impacting your availability model. This 
solution takes into account servers, networking, storage and other 
infrastructure. Find additional information at Dell.com/FreshAir.
