How is comprehensive thermal management achieved?

Comprehensive thermal management is achieved by regulating the fan speed based on several different responses from all system component temperature sensors, as well as inventory for system configurations.

---

What does temperature monitoring include?

Temperature monitoring includes components such as processors, DIMMs, chipset, the inlet air ambient, hard disk drives, and LOM riser.

---

What does open and closed loop thermal fan control use to determine fan speed?

Open and closed loop thermal fan 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.

---

Where can I find user-configurable settings for thermal control?

User-configurable settings can be found in the iDRAC BIOS setup screen.

---

What does N+1 fan redundancy allow?

Cooling N+1 fan redundancy allows continuous operation with one fan failure in the system.

---

What makes the PowerEdge R7525 appropriate for attended data center environments?

The PowerEdge R7525 is a rack-mount server appropriate for attended data center environments. However, lower acoustical output is attainable with proper hardware or software configurations.

---

Is the minimum configuration of R7525 quiet enough for a typical office environment?

Yes, the minimum configuration of R7525 is quiet enough for a typical office environment.

What does the acoustical design of the PowerEdge R7525 reflect?

The acoustical design of the PowerEdge R7525 reflects the following:

• Versatility—The PowerEdge R7525 has a reduced power draw in the data center. It is also quiet enough for an office environment in typical and minimum configurations.
• High sound quality standards—Sound quality is different from sound power level and sound pressure level in that it describes how humans respond to sound annoyance such as whistles and hums. One of the sound quality metrics in the Dell specifications is the prominence ratio of a tone.
• Noise ramp and descent at boot from power-off—Fan speeds and noise levels ramp during the boot process (from power off to power on) to add a layer of protection to component cooling in when the system is not able to boot properly. To keep the boot process as quiet as possible, the fan speed reached during boot is limited to about half of full speed.

---

What should I consider if acoustics are important to me?

If acoustics are important, consider several configuration choices and settings:

• For lower acoustical output, use a few lower rotational speed SATA hard drives, nearline SAS hard drives, or non-rotational devices such as SSDs. 15 k hard drives generate more acoustic noise than lower rotational speed hard drives. Also, noise increases with the number of hard drives.
• Fan speeds and noise may increase from baseline factory configurations when certain profiles are changed by the user, or system configurations are updated. The following is a list of items that impact fan speeds and acoustical output:
  • iDRAC9 BIOS settings—Performance Per Watt, DAPC or operating system, may be quieter than Performance or Dense Configuration (iDRAC Settings > Thermal > Max. Exhaust Temperature or Fan speed offset).
  • The quantity and type of PCIe cards installed—This affects overall system acoustics. Installation of more than two PCIe cards results in an increase in overall system acoustics.
  • Using a GPU card—GPU card results in an increase in overall system acoustics.
  • PCIe controller-based SSD drives—Drives such as express flash drives and Fusion IO cards require greater airflow for cooling, and result in higher noise levels.
  • Systems with an H330 PERC—This configuration may be quieter than configurations with an H740P PERC with battery backup. However, higher noise levels result when a system is configured as non-RAID.
  • Hot spare feature of power supply unit—In the system default setting, the hot spare feature is disabled. Acoustical output from the power supplies is lowest in this setting.
