4.6 Thermal
The thermal design of the PowerEdge R515 includes the following:
∙Closed loop thermal control algorithm: This method uses feedback temperatures to dynamically determine proper fan speeds.
∙Comprehensive thermal management: The PowerEdge R515 controls system cooling fan speed based on several different responses from critical component sensors, such as processor temperature, DIMM temperature, IOH temperature, inlet ambient temperature, and system configurations. The thermal management adjusts proper cooling ability for the system according to what the system really needs.
∙Optimized Ventilation: The R515 chassis has a custom ventilation design for optimized air flow path. Each component and peripheral is ensured sufficient air for cooling.
∙Redundant Cooling: The R515
4.7 Acoustics
The acoustical design of the PowerEdge R515 reflects adherence to Dell’s high sound quality standards. Sound quality is different from sound power level and sound pressure level in that it describes how humans respond to annoyances in sound, like whistles, hums, etc. One of the sound quality metrics in the Dell specification is prominence ratio of a tone as shown in Table 6 and 0.
Fan speeds and noise levels ramp up during the boot process to add a layer of protection for component cooling if the system were not to boot properly. Hardware configurations affect system noise levels. Dell’s thermal control provides for optimized cooling with varying hardware configurations, as shown in the following tables.
