– Operating Modes
Select this choice to view or change the operating profile (performance and power utilization). This
choice specifies a preset operating mode to configure the server for maximum power savings,
maximum efficiency, and maximum performance.
– Minimal Power mode
Select this choice to minimize the absolute power consumption of the system during operation.
Server performance in this mode might be reduced depending on the application that is running.
– Efficiency-Favor Power mode
Select this choice to configure the server to draw the minimum amount of power and generate the
least noise. Server performance might be degraded, depending on the application that you are
running. This mode provides the best features for reducing power and increasing performance in
applications where the maximum bus speeds are not critical.
– Efficiency-Favor Performance mode
Select this choice to maintain the optimal balance between performance and power consumption.
The server generally produces the best performance per watt while it is in this mode. No bus speeds
are derated in this mode. This is the default mode.
– Custom mode
Select this choice only if you understand the functions of the low-level IMM settings. This is the only
choice that enables you to change the low-level IMM settings that affect the performance and power
consumption of the server.
– Maximum Performance mode
Select this choice to achieve the maximum performance for most server applications. The power
consumption in this mode is often higher than in the Efficiency-Favor Power or Efficiency-Favor
Performance mode.
– Power
Select this choice to view or change power capping to control consumption, processors, and
performance states.
