IBM Power 750 and 760 Technical Overview and Introduction
The Power 750 and Power 760 systems implement all the EnergyScale capabilities listed in
2.13.1, “IBM EnergyScale technology” on page 105.
2.13.2 Thermal power management device card
The thermal power management device (TPMD) card is a separate micro controller installed
on some POWER6 processor-based systems, and on all POWER7 and
processor-based systems. It runs real-time firmware whose sole purpose is to manage
system energy.
The TPMD card monitors the processor modules, memory, environmental temperature, and
fan speed. Based on this information, it can act upon the system to maintain optimal power
and energy conditions (for example, increase the fan speed to react to a temperature
change). It also interacts with the IBM Systems Director Active Energy Manager to report
power and thermal information and to receive input from AEM on policies to be set. The
TPMD is part of the EnergyScale infrastructure.
2.13.3 Energy consumption estimation
Often, for Power Systems, various energy-related values are important:
Maximum power consumption and power source loading values
These values are important for site planning and are in the hardware information center:

Search for type and model number and
server specifications
. For example, for the
Power 760 system search for
9109-RMD server specifications
.
An estimation of the energy consumption for a certain configuration
The calculation of the energy consumption for a certain configuration could be done in the
IBM Systems Energy Estimator:
http://www-912.ibm.com/see/EnergyEstimator/
In that tool, select the type and model for the system, enter several details of the
configuration and a desired CPU utilization. As a result, the tool shows the estimated
energy consumption, and the waste heat at the desired utilization and at full utilization.
