Intel S1200BTL Product Specification - Page 55

Intel®Server Board S1200BT TPS Platform Management The NM feature is implemented by a complementary architecture utilizing the ME, Integrated BMC, BIOS, and an ACPI-compliant OS. The ME provides the NM policy engine and power control/limiting functions (referred to as Node Manager or NM) while the Integrated BMC provides the external LAN link by which external management software can interact with the feature. The BIOS provides system power information utilized by the NM algorithms and also exports ASL code used by OSPM for negotiating processor P and T state changes for power limiting. PMBus-compliant power supplies provide the capability to monitoring input power consumption, which is necessary to support NM. The NM architecture applicable to this generation of servers is defined by the NPTM Architecture Specification v2.0. NPTM is an evolving technology that is expected to continue to add new capabilities that will be defined in subsequent versions of the specification. The ME NM implements the NPTM policy engine and control/monitoring algorithms defined in the NPTM specification. 4.4.2 Features NM provides feature support for policy management, monitoring and querying, alerts and notifications, and an external interface protocol. The policy management features implement specific IT goals that can be specified as policy directives for NM. Monitoring and querying features enable tracking of power consumption. Alerts and notifications provide the foundation for automation of power management in the data center management stack. The external interface specifies the protocols that must be supported in this version of NM. The table below summarizes the feature support for NM 2.0. Table 12.
