Table 8-11. System Power Policy Configuration
Item Description
System Input
Power Cap
Displays the user configured maximum power consumption limit
for the entire system (chassis, CMC, servers, I/O modules, power
supply units, iKVM, and fans). The CMC will enforce this limit via
reduced server power allocations, or by powering off lower priority
server modules. The value for system input power cap is displayed
in watts, BTU/h and percent units.
If the chassis power consumption exceeds the System Input Power
Cap, then the performance of lower priority servers is reduced until
total power consumption falls below the cap.
In cases where the servers are set to the same priority, then the
selection of the server for power reduction, or power-off action, is
based on the server slot number order. For example, the server in
slot 1 is selected first and the server in slot 16 is selected last.
Surplus for Peak
Performance
The surplus for peak performance value is the difference
between
the System Input Power Cap and the 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.
