Description
Intel Node Manager is an embedded technology that provides individual
server-level power reporting and power limiting functionality. 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.
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.
With the thermal design and reliability of Dell products, you can have the
capability to operate at excursion-based temperatures. This solution is
comprised of servers, networking, storage, and infrastructure that run
beyond the industry standard of 35°C (95°F) 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
