– Adapters and UEFI Drivers
Select this choice if you want to use the configuration capabilities of the device drivers to configure
the device.
– Processors
Select this choice to view or change the processor settings.
– Memory
Select this choice to view or change the memory settings. To configure memory mirroring, select
System Settings > Memory > Memory Mode > Mirroring .
– Devices and I/O Ports
Select this choice to view or change settings for devices and input/output (I/O) ports. You can configure
the serial ports and remote console redirection; enable or disable the ML2 adapter, SATA optical drive
channels, and PCI slots. If you disable a device, it cannot be configured, and the operating system will
not be able to detect it (this is equivalent to disconnecting the device).
– Power
Select this choice to view or change power capping to control consumption, processors, and
performance states.
– Active Energy Manager
Select this choice to enable or disable Active Energy Manager Power Capping. If you enable Power
Capping, the Active Energy Manager program will limit the maximum power that is consumed by
the server.
– Workload Configuration
Select this choice to determine how to balance between I/O bandwidth and balanced workload.
Choosing
I/O sensitive will get higher I/O bandwidth when expansion cards are used. Choosing
Balanced will allow enough frequency for the workload while the microprocessor cores are idle.
– 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.
– Choose Operating Mode
Select the operating mode based on your preference. Power savings and performance are
dependent on hardware configuration and software running on the system. When a present mode is
selected, the low-level settings are not changeable and will be grayed out.
• 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.
• Maximum Performance mode
