ProLiant DL360 G4 and G4p Server High Density Deployment Solution White Paper

Conclusion

The load requirements of high density server installations can be significant. Careful planning using

accurate calculations and providing adequate additional capacity allowance for peripheral devices

can greatly reduce the likelihood of downtime because of power problems.

Power Regulator for ProLiant Servers

Power Regulator is an innovative operating system-independent power management feature of HP ProLiant

servers that offers new alternatives to manage server power consumption and system performance to meet

critical business needs.

This new power management technology enables dynamic or static changes in processor performance and

power states. In dynamic mode, Power Regulator automatically adjusts the processor power usage and

performance of the server to match processor application activity. This improves server energy efficiency by

giving processors full power for applications when they need it and enabling power savings without

performance degradation when application activity is reduced. Power Regulator effectively executes

automated policy-based power management at the individual server level. In addition, a static power

savings mode allows servers to run continuously in a lowest power state for the system.

Benefits

Power Regulator for ProLiant servers offers several benefits to customers:

• Saves on system power and cooling costs by enabling ProLiant servers to operate more

efficiently by consuming less power and reducing BTU output during periods of reduced server

activity.

• Increases facility compute capacity by increasing system efficiency and freeing up system

and cooling power for use when and where it is required, maximizing the use and efficiency of

your power pool.

• Enables extensive deployment because Power Regulator is supported today on Intel® Xeon™

3.6-, 3.4-, and 3.2-GHz–based HP ProLiant servers giving customers a wide choice of power-

efficient servers. (Power Regulator will be supported across all Intel- and AMD-based HP ProLiant

ML/DL 300 and 500 as well as BL servers as processor enablement becomes available.)

• Offers operating system independence since Power Regulator can be used on any

supported ProLiant server with no requirements for costly and time-consuming operating system

upgrades.

• Provides flexible and scalable setup with configuration support on a single system from the

ROM Based Setup Utility (RBSU), integrated Lights-Outs (iLO) browser, and command line. Volume

server setup is supported using the iLO scripting interface with batch processes or the Rapid

Deployment Pack or HP Systems Insight Manager.

• Protects the environment by conserving energy through increased energy efficiency in the

data center or computer room, which allows businesses to achieve greater standing as

environmentally conscious global citizens.
