27 PowerEdge R320 Technical Guide
Active power management
(hot-plug PSU only)
Intel Node Manager: Dell offers a complete power management solution
comprised of Intel Node Manager accessed through Dell iDRAC7 Enterprise
and OpenManage Power Center that allows policy-based management of
power and thermals at the individual server, rack, and data center level. Intel
Node Manager is an embedded technology that provides individual server-
level power reporting and power limiting functionality.
Hot spare reduces power consumption of redundant power supplies.
Thermal control of fan speed optimizes the thermal settings for your
environment to reduce fan consumption and lower system power
consumption.
Idle power enables Dell servers to run as efficiently when idle as when at full
workload.
Dell Fresh Air cooling
(Dual PSUs required)
With the thermal design and reliability of Dell products, certain
configurations have the capability to operate at excursion-based
temperatures beyond the industry standard of 35°C (95°F) up to 45°C
(113°F) for excursionary periods of time and up to a 26°C dew point at
90% relative humidity; without impacting your availability model. Find
additional information at Dell.com/FreshAir.
Dell offers some of the industry’s highest-efficiency power infrastructure
solutions, including:
Power distribution units
Uninterruptible power supplies
Energy Smart containment rack enclosures

Power supply units
Energy Smart power supplies (hot-plug PSUs only) have intelligent features, such as the ability to
dynamically optimize efficiency while maintaining availability and redundancy. Also featured are
enhanced power-consumption reduction technologies, such as high-efficiency power conversion
and advanced thermal-management techniques and embedded power-management features,
including high-accuracy power monitoring.
The R320 power supply subsystem consists of one non-redundant or up to two hot-plug AC-DC
power supplies. The power supply provides +3.3V/5V/12V and +12Vaux for non-redundant design
and provides 12V and 12Vaux for redundant design. There are several voltage regulators in the
system to supply different voltage levels needed by different logic devices. The redundant power
supplies are managed through a PMBus interface.
The following power supply options are available for the R320:
350W AC, cabled, non-redundant
350W AC, hot-plug redundant
550W AC, hot-plug redundant
