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: The power budget threshold cannot be more than Maximum Potential
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.
