HP Power Regulator This feature configures the Power Regulator for ProLiant support. Options include: • HP Dynamic Power Savings Mode (default)-Automatically varies processor speed and power usage based on processor use, reduces overall power consumption with little or no impact to performance, and does not require OS support. • HP Static Low Power Mode-Reduces processor speed and power usage, guarantees a lower maximum power usage for the system, and provides a high impact on performance in environments with higher processor utilization. • HP Static High Performance Mode-Processors run in the maximum power and performance state, regardless of the OS power management policy. • OS Control Mode-Processors run in the maximum power and performance state, unless the OS enables a power management policy. NOTE: Certain processors support only one power state and operate at their initialized frequency, regardless of the Power Regulator setting.
