*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".

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
*8
–1).
•
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, the server might not start normally after shutdown.
