Managing processor technologies
HP leverages several of the power management technologies built into AMD Opteron 6100 series
processor. This suite of technologies includes AMD PowerNow™ Technology, enhanced Advanced
Platform Management Link (APML), and AMD Power Cap Manager™.
APML Remote Power Management Interface
The A
MD Opteron six-core 6100-series processors incorporate multiple thermal sensors to indicate the
hottest part of the processor. Using a systems management device such as iLO, you can remotely
monitor and control P-state limits using AMD’s APML Remote Power Management Interface. The iLO
processor includes the processor thermal data in the data it sends to the fan controller.
Enhanced APML
Enhanc
ed APML is a new capability offered on HP ProLiant G7 platforms with the AMD 6100 series
processors. This capability includes a Precision Thermal Monitor feature that provides a more precise
digital readout of CPU thermals, monitors power/cooling, and alerts the Baseboard Management
Controller (BMC). HP ProLiant thermal policy relies on enhanced APML for accurate processor thermal
information.
AMD CoolCore™
This
AMD technology reduces processor energy consumption by turning off unused parts of the
processor. This in turn helps reduce power and cooling costs for the IT infrastructure. AMD CoolCore
is enabled by default and is not a user option.
