Item Description
Default
Value
Configuration
Power Threshold(Pn) Specify power threshold in Non-Aggressive Mode. Allowable range is between
the Minimum Power Consumption and BBB (Watt).

Power Consumption
+10
Correction time limit
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.

Performance Mode
Select a performance at system boot-up.
*7
Performance Optimized
: Prefer performance and operation
Power Optimized
: Optimize power consumption.

Disable CPU Cores
Specify the number of cores to be disabled. Allowable value is between 0 and
(Number of maximum cores –1).

Configuration
Initialization
Initialize configuration. Parameters for ECO setting are returned to default
value.
–
*1: These values are reference purpose only. Each value might be different from the actual value which depends on your
system configuration.
*2: Technology that decreases frequency or duty cycle of clock, and suppresses power consumption.
*3: Can be specified only when Aggressive Mode is set to "Enable".
*4: AAA denotes "Minimum Power Consumption" or "Power Threshold (Pn)".
*5: Can be specified only when Non-Aggressive Mode is set to "Enable".
*6: BBB denotes "Maximum Power Consumption" or "Power Threshold (Pa)".
*7: Can be specified only when Boot Time Configuration is set to "Enable".
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.
