Surplus for Peak
Performance
The surplus for peak performance value is the difference
between the System Input Power Cap and the Power
Required for Peak Performance (sum of the Maximum Input
Power Allocated to Servers and the Maximum Input Power
Allocated to Chassis Infrastructure). The value for surplus
for peak performance is indicated in both the watts and
BTU/h units.
Power Required for
Peak Performance
The power required for peak performance value is the sum
of
the Maximum Input Power Need of Servers that are powered
on and the Input Power Allocated to Chassis Infrastructure.
The value for power required for peak performance is
indicated in both the watts and BTU/h units. If System Input
Power Cap is set to less than Power Required for Peak
Performance, some servers may throttle under extreme load.
