Power Budget Threshold; Using The Web-Based Interface - Dell IDRAC6 User Manual

Power Budget Threshold

Power Budget Threshold, if enabled, allows a power capping limit to be set for
the system. System performance will be dynamically adjusted to maintain
power consumption near the specified threshold. Actual power consumption
may be less for light workloads and may momentarily exceed the threshold
until performance adjustments have completed.
If you check Enabled for the Power budget Threshold, the system will enforce
the user-specified threshold. If you leave the Power budget Threshold value
unchecked, the system will not be power capped. For example, for a given
system configuration, the Maximum Potential Power Consumption is 700W
and the Minimum Potential Power Consumption is 500W. You can specify
and enable a Power Budget Threshold to reduce consumption from its current
650W down to 525W. From that point on the system's performance will be
dynamically adjusted to maintain power consumption so as to not exceed the
user-specified threshold of 525W.

Using the Web-Based Interface

1 Log in to the iDRAC6 Web-based interface.
2 Click the Power tab.
3 Select the Power Budget option. The Power Budget Information page
displays.
4 Enter a value in Watts, BTU/hr, or percent in the Power Budget table. The
value you specify in Watts or BTU/hr will be the power budget threshold
limit value. If you specify a percentage value, it will be a percentage of the
Maximum-to-Minimum Potential Power Consumption interval. For
example, 100% Threshold means Maximum Potential Power
Consumption while 0% means Minimum Potential Power Consumption.
NOTE:
Power Consumption or less than Minimum Potential Power Consumption.
5 Select the Enabled checkbox to enable the threshold. The system will
enforce the user-specified threshold. If you clear the checkbox, the
system will not be power capped.
6 Click Apply Changes.
