*1: These values are reference purpose only. Each value might be different from the actual value which depends
on your precise server configuration.
*2: Technology that decreases frequency or duty cycle of clock, and suppresses power consumption.
*3: This item is not displayed when the system does not support this function.
*4: Can be specified only when Aggressive Mode is set to "Enable".
*5: AAA denotes "Standby power at minimum configuration" or "Power Threshold(Pn)".
*6: Can be specified only when Non-Aggressive Mode is set to "Enable".
*7: BBB denotes "Operating power at maximum configuration" or "Power Threshold(Pa)".
*8: Can be specified only when Boot Time Configuration is set to "Enable".
Enable or disable Non-Aggressive Mode.
Specify power threshold in Non-Aggressive Mode.
Allowable range is between BBB and Standby power
at minimum configuration (Watt).
When power consumption exceeds the power
threshold for Non-Aggressive Mode and unable to
recover within the time period specified in this
parameter, collects event log and sends an alert.
Allowable value (in seconds) depends on system.
*3 Enable or disable Safe Power Capping (Monitoring at
unreadable power consumption).
Enable or disable Boot Time Configuration.
Select a performance at system boot-up.
Performance Optimized
: Prefer performance and operation
Power Optimized
: Optimize power consumption.
Specify the number of cores to be disabled. Allowable
values are between 0 and (Number of maximum cores
–1). *8
Note • The power value may not reach the threshold value. The power control feature saves
power consumption by lowering the clock speed of CPU/memory. If the throttling value
of CPU/memory reaches 100%, the power value cannot be reduced no longer.
• If the value specified for Power Threshold(Pa) for Aggressive Mode is lower than the
power required for system startup and the parameter "Shutdown System" is enabled,
the server might not start normally after shutdown.
When validating this setup, it is recommended to fully consider the value of "Power
Threshold (Pa)" to be specified.
