Figure 8. Thermal design characteristics
The thermal design of the PowerEdge T150 reflects the following:
Optimized thermal design: The system layout is architected for optimum thermal design.
System component placement and layout are designed to provide maximum airflow coverage to critical components with
minimum expense of fan power.
Comprehensive thermal management: The thermal control system regulates the fan speed based on several different
responses from all system-component temperature sensors, as well as inventory for system configurations. Temperature
monitoring includes components such as processors, DIMMs, chipset, the inlet air ambient, hard disk drives, and OCP.
Open and closed loop thermal fan speed control: Open loop thermal control uses system configuration to determine
fan speed based on inlet air ambient temperature. Closed loop thermal control method uses feedback temperatures to
dynamically determine proper fan speeds.
User-configurable settings: With the understanding and realization that every customer has unique set of circumstances or
expectations from the system, in this generation of servers, we have introduced limited user- configurable settings residing
in the iDRAC BIOS setup screen. For more information, see the Dell EMC PowerEdge T150 Installation and Service Manual
at www.dell.com/poweredgemanuals and Advanced Thermal Control: Optimizing across Environments and Power Goals on
Dell.com.
Cooling redundancy: The T150 allows N+1 fan redundancy, allowing continuous operation with one fan failure in the system.
Environmental Specifications: The optimized thermal management makes the T150 reliable under a wide range of operating
environments.
Thermal restrictions
ASHRAE A4 environment
3.5-inch hard drive count is restricted to 2x drives per chassis
Acoustics
Acoustical design
Dell EMC PowerEdge delivers sound quality and smooth transient response in addition to sound power levels and sound pressure
levels oriented to deployment environments.
Sound quality describes how disturbing or pleasing a person finds a sound, as a function of a variety of psycho-acoustical
metrics and thresholds. Tone prominence is one such metric.
