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.
