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 power capping. If you enable power
capping, the Active Energy Manager program will limit the maximum
power that is consumed by the server.
Note: It is available only when System Settings → Processors → Processor
Performance States is enabled.
- Power/Performance Bias
Select this choice to determine how the power management of the
microprocessor is controlled. You can choose either Platform Controlled
(system) or OS Controlled (operating system) to control the setting. Not all
operating systems support this feature.
- Platform Controlled Type
Select this choice to determine how to balance between performance and
power consumption. Choosing Maximum Performance will disable power
management functions and allow the most aggressive use of turbo.
Choosing Minimal Power will maximizes the use of power management
features for least power consumption and disable turbo.
Note: It is available only when System Settings → Power →
Power/Performance Bias → Platform Controlled is enabled.
- 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
while expansion cards are used. Choosing Balanced will allow enough
frequency for 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 specify 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 also highly dependent on hardware and software running
on the system. When a present mode is selected, the low-level settings are
not changeable and will be grayed out.
- Memory Speed
Select the desired memory speed. Maximum performance mode maximizes
performance. Balanced mode offers a balance between performance and
power. Minimal power mode maximizes power savings.
- Memory Power Management
Select this choice to enable or disable power management on memory. If
you choose Disabled, it will provide maximum performance but minimum
power savings. If you choose Automatic, it is suitable for most applications.
- Proc Performance States
