35 PowerEdge R720 and R720xd Technical Guide
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 iDRAC 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 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.
