Accurate power control

Accurate power control (APC) function restricts the power consumption of
system unit depending on the designated unique maximum power
consumption by using the server blade power capping function. The APC is
implemented with software control so the actual power consumption may
exceed the designated maximum value.
When the excess power consumption is detected, the APC reduces the
processor frequency of server blade to appropriate level and restores the
power consumption within the designated maximum value. The frequency
reduction causes the performance suppression and the status lasts one
minute. The APC automatically calculates the applicable frequency for each
server blade to meet its maximum power consumption goal.
