8 Power, thermal and acoustics

Lower overall system-level power draw is a result of Dell's breakthrough system design. The
PowerEdge VRTX chassis maximizes performance-per-watt through a combination of power and
cooling, energy-efficient technologies, and tools. Additionally, VRTX 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 6 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.
Energy Smart Solution Advisor (ESSA) 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.
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 OpenManage 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.
iDRAC7 Enterprise with Lifecycle Controller 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 (PDUs)
and uninterruptible power supplies.
