at ≤ 50% relative humidity)

Acoustics
The acoustical design of the PowerEdge M710 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 or hums. Definitions for
acoustical performance data are as follows:
•
Idle:
Reference ISO7779 (2010) definition 3.1.7; system is running in its OS but no other
specific activity.
•
LwA–UL:
The upper limit sound power level (LwA) calculated per section 4.4.2 of ISO 9296
(1988) and measured in accordance to ISO 7779 (2010).
Table 4 shows the acoustical performance for a typical configuration of the M1000e chassis with eight
PowerEdge M710 blade servers installed. Acoustical performance varies with hardware
configurations.

Thermal
The M710 thermal solution includes:
Optimized airflow impedance for individual blade and chassis level airflow balancing
Custom air baffling to direct air flow through the components to maintain proper cooling
Custom-designed heat sinks that maintain CPU, DIMM, and board-level chip temperatures
within thermal design targets
Highly optimized fan control algorithm:
