Forum for discussions of and reporting issues related to the available IBM Energy Management Blueprints located on IBM's Information Center for Linux.

• The IBM Blueprint for monitoring and controlling power consumption on Linux describes how to monitor and control power use on System X servers that have the relevant hardware features--specifically, systems that support either Intel's Enhanced Speed Step (EIST) or AMD's PowerNow, and have power meter hardware installed.


• The CPUFreq Blueprint describes how to use the Linux CPUFreq subsystem on RHEL5.3 to exploit the processor performance state (P-state) feature that is commonly available to newer processors. This feature can be configured to statically alter the processor operating frequency or dynamically scale the frequency to the current processor usage, so that less power is consumed without performance loss.
