Three are four modes in which the power regulator can operate. The power regulator
modes (Static Low, Static High and Dynamic) are independent of the operating system
and work for any operating system. The OS Control Mode requires Microsoft Windows
Server 2003 SP1 or later or Red Hat Linux 4 Update 2 or later.
Sets the processors to the appropriate power level based on the utilization of each CPU
core during the last 1/8 second. The CPU is set to the power saving processor power
state if the CPU is operating at a utilization level that can be completed at the slower
CPU frequency. The CPU is set to the maximum performance processor power state
if the CPU is operating at a utilization level that requires the fastest CPU frequency.
Sets the processor to the lowest supported processor state and forces the CPUs to stay
in that lowest state. This mode saves the maximum amount of resources, but it might
affect the system performance if processor utilization stays at or above 75% utilization.
Sets the processor to the highest supported processor state and forces the CPUs to stay
in that highest state. This mode ensures maximum performance, but it does not save
any resources. This mode can be used to create a baseline of power consumption data
without the power regulator.
Configures the server to enable the operating system to control the processor power
states. This is the necessary setting for OS power management. Moving from this state
to any of the three previous states does not require a server reboot because Integrity
iLO 2 power regulation works in cooperation with the OS. (This is different from
ProLiant iLO power regulation).
