Power Regulator Mode

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.

Enable Dynamic Power

Sets the processors to the appropriate power level based on the utilization of each CPU

Savings Mode

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.

Enable Static Low Power

Sets the processor to the lowest supported processor state and forces the CPUs to stay

Mode

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.

Enable Static High

Sets the processor to the highest supported processor state and forces the CPUs to stay

Performance Mode

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.

Enable OS Control Mode

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 requires a server reboot.

Submit

Submits the selected function.

Cancel

Cancels the action.

Power regulation requires the server to have both a CPU and an operating system that is capable of power regulation. Power regulation functions are available only when the OS is booted, and the system has the required hardware, firmware, OS, and software.

The power regulation functionality is achieved through two different interfaces:

Power Regulation through HP SIM (using the HP IPM plug in)

HP Insight Power Manager (HP IPM), a plug-in to HP Systems Insight Manager (HP SIM), is an integrated power monitoring and management application that provides centralized control of server power consumption and thermal output. It extends the unified infrastructure management framework of HP SIM by providing new energy levers into the server.

Leveraging HP power regulator technology, HP IPM makes policy-based power and thermal management possible. It expands the capacity of data centers by reducing the amount of power and cooling required for supported Integrity servers and the server blades.

An Advanced Pack license is required to use the power regulation feature through the IPM. Information on HP IPM is available on the HP website at: http://www.hp.com/go/ipm

Power Regulation through the iLO 2 MP

The iLO 2 MP reads ACPI registers to gather information and display the current power efficiency mode of the system. The available power regulator mode settings are sent to the OS through an ACPI interface. If the OS is able to respond to the settings, it sets return codes to note success or failure to reach these settings.

You do not need an Advanced Pack license to use the power regulation feature through iLO 2 MP.
