Dell PowerEdge M520 Technical Guide - Page 27

Feature Description 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. Fresh Air 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. Rack infrastructure Dell offers some of the industry's highest-efficiency power infrastructure solutions, including:  Power distribution units  Uninterruptible power supplies  Energy Smart containment rack enclosures Find additional information at http://content.dell.com/us/en/enterprise/ power-and-cooling-technologies-components-rack-infrastructure.aspx. Find additional information at Dell.com/PowerAndCooling and Power.com/PowerCenter. Power supply units The M1000e chassis enclosure provides power and cooling for the M520 blade server. For information on the M1000e power supply units, see the PowerEdge M1000e Technical Guide on Dell.com/PowerEdge. Thermal and acoustics Optimized thermal management keeps fan speeds in the PowerEdge M520 as low as possible, contributing to quiet operation and ensuring proper component cooling. Thermal design The thermal design of the PowerEdge M520 reflects the following:  Comprehensive thermal management: The PowerEdge M520 dynamically controls system cooling fan speed, based on responses from critical sensors that monitor the temperature of several components, including: - Processors - DIMMs - System inlet ambient - Mezzanine card Thermal control also detects and responds to hardware configuration. Thermal management adjusts cooling according to what the system really needs, and draws lower fan power draw and generates lower acoustical noise levels than those without such controls. 27 PowerEdge M520 Technical Guide
