2.13 IBM EnergyScale

IBM EnergyScale technology provides functions to help the user understand and dynamically

optimize the processor performance versus processor power and system workload, to control

IBM Power Systems power and cooling usage.

The BladeCenter AMM and IBM Systems Director Active Energy Manager exploit

EnergyScale technology, enabling advanced energy management features to conserve

power and improve energy efficiency. Intelligent energy optimization capabilities enable the

POWER7 processor to operate at a higher frequency for increased performance and

performance per watt, or reduce frequency to save energy.

2.13.1 IBM EnergyScale technology

This section describes IBM EnergyScale design features, and hardware and software

requirements.

IBM EnergyScale consists of the following elements:

򐂰 A built-in EnergyScale device (formally known as Thermal Power Management Device or

TPMD)

򐂰 Power executive software. IBM Systems Director Active Energy Manager, an IBM

Systems Directors plug-in and BladeCenter AMM.

IBM EnergyScale functions include the following elements:

򐂰 Energy trending

EnergyScale provides continuous collection of real-time server energy consumption. This

function enables administrators to predict power consumption across their infrastructure

and to react to business and processing needs. For example, administrators might use

such information to predict data center energy consumption at various times of the day,

week, or month.

򐂰 Thermal reporting

IBM Systems Director Active Energy Manager can display measured ambient temperature

and calculated exhaust heat index temperature. This information can help identify data

center hot spots that require attention.
