The 11G family of PowerEdge servers implements aspects of Dell's Energy Smart strategy. This
strategy offers the following:
Energy Smart components on a portfolio level, such as high-capacity and Energy Smart power
supplies
Systems with either a lowest power footprint configuration or a best performance per watt
configuration
Energy Smart components (such as DIMMs or hard drives) selected without cherry picking or
screening individual manufacturer's components based on energy consumption

5.10 Acoustics
The acoustical design of the PowerEdge R710 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 7.
