Dell™ PowerEdge™ R610 Technical Guidebook17G. energysmaRt enablementThe 11G family implements aspects of Dell’s new Energy Smart strategy.Major differences include:• Discontinuing Energy Smart-branded servers with limited configurations and instead offeringEnergy Smart components on a portfolio level, such as high capacity and Energy Smart powersupplies• Allowing customers to order either a lowest power footprint configuration or a bestperformance-per-watt configuration• Offering Energy Smart selected components such as DIMMs or hard drives, but not “cherrypicking" or screening individual manufacturers' components based on energy consumption.h. acousticsThe acoustical design of the PowerEdge R610 reflects the following:• Adherence to Dell’s high sound-quality standards. Sound quality is different from sound powerlevel 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 prominenceratio of a tone, and this is listed in the table below.• Office environment acoustics. Compare the values for LpA in the table below and note thatthey are lower than ambient noise levels of typical office environments.• Hardware configurations affect system noise levels. Dell’s advanced thermal control providesfor optimized cooling with varying hardware configurations. Most typical configurations willperform as listed in the table below. However some less typical configurations and componentscan result in higher noise levels, for example, a system configured with a PERC6/E card (notedin table below). (Please note that dBA values are not additive.)• Noise ramp and descent at bootup.• Fan speeds, hence noise levels, ramp during the boot process in order to add alayer of protection for component cooling in the case that the system were not toboot properly.• The power supplies are passive in the R610, that is, they contain no internal fans.After power is connected to the power supplies, initialization of power supplycommunication with the server’s fan control firmware takes place and assesses ifcooling is required in standby mode. It is therefore normal for chassis fan #1 tooperate at full speed for approximately 30 seconds after power is connected tothe system. The fan will ramp down to a full stop after this time period in <_ 25° Cambient conditions.
