1.8 Advanced Power Management

The following new advanced power management features are supported by the motherboard.
Intel Intelligent Power Node Manager (IPNM)
®
Available when the Supermicro Power Manager (SPM) is installed, Intel's Intelligent Power
Node Manager (IPNM) provides your system with real-time thermal control and power
management for maximum energy efficiency. Although IPNM Specification Version 2.0/3.0
is supported by the BMC (Baseboard Management Controller), your system must also have
IPNM-compatible Management Engine (ME) firmware installed to use this feature.
Note: Support for IPNM 2.0/3.0 support is dependent on the power supply used in
the system.

Management Engine (ME)

The Management Engine, which is an ARC controller embedded in the IOH (I/O Hub), provides
Server Platform Services (SPS) to your system. The services provided by SPS are different
from those provided by the ME on client platforms.
