Dell server and storage power supplies. What to consider.

Power supplies are optimized to run with high-line (230V) input voltage. While PowerEdge power supplies support auto-ranging, low-line (115V) operation can reduce overall efficiency by about 2%.

  • When you order redundant power supply configurations, overall system power efficiency is reduced by power supplies sharing the load and operating at a lower point on their efficiency curves.
  • Rack and tower PowerEdge servers support Power Supply Hot Spare, which puts the redundant power supply in a “sleep state” to remove the efficiency impact of redundant power supply configurations.
    • Hot Spare is enabled by default, and you can select which of the power supplies will be the hot spare primary.
    • This should be the power supply on the most cost-effective and power-efficient grid, as the primary power supply may see the majority of the load.
  • Rack and tower PowerEdge servers also support the ability to disable power factor correction (PFC) to reduce power consumption when the system is in standby (S5 state).
  • DAPC is a Dell proprietary implementation of dynamic processor power management that provides superior performance-per-watt compared to OS-based dynamic power management.
  • Unlike unique OS implementations, DAPC provides consistent results regardless of the operating system and provides dynamic processor power management even if it is not supported by the OS or hypervisor.
  • DAPC System profile is configured in the factory when you select “Power Saving Dell Active Power Controller” in the ordering tool.

This is the recommended profile for performance-per-watt.
