Power Supply Units - Dell PowerEdge R620 Technical Manual

Lower overall system-level power draw is a result of Dell's breakthrough system design. The R620
PowerEdge server maximizes performance per watt through a combination of power and cooling,
energy efficient technologies, and tools. Additionally, the PowerEdge R620 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 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 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.
Dell's servers are compliant with all relevant industry certifications and
guidelines, including 80 PLUS, Climate Savers, and
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
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
circuit-breaker fast capping.
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.
