Platform Management Intel® Server Board S1200BT TPS 4.3.2 Fan Speed Control BIOS and BMC software work cooperatively to implement system thermal management support. During normal system operation, the BMC will retrieve information from the BIOS and monitor several platform thermal sensors to determine the required fan speeds. In order to provide the proper fan speed control for a given system configuration, the BMC must have the appropriate platform data programmed. Platform configuration data is programmed using the FRUSDR utility during the system integration process and by System BIOS during run time. 4.3.2.1 System Configuration Using the FRUSDR Utility The Field Replaceable Unit and Sensor Data Record Update Utility (FRUSDR utility) is a program used to write platform-specific configuration data to NVRAM on the server board. It allows the user to select which supported chassis (Intel® or Non-Intel) and platform chassis configuration is used. Based on the input provided, the FRUSDR writes sensor data specific to the configuration to NVRAM for the BMC controller to read each time the system is powered on. 4.4 Intel® Intelligent Power Node Manager 4.4.1 Overview Power management deals with requirements to manage processor power consumption and manage power at the platform level to meet critical business needs. Node Manager (NM) is a platform resident technology that enforces power capping and thermal-triggered power capping policies for the platform. These policies are applied by exploiting subsystem knobs (such as processor P and T states) that can be used to control power consumption. NM enables data center power management by exposing an external interface to management software through which platform policies can be specified. It also implements specific data center power management usage models such as power limiting, and thermal monitoring. 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 46 Revision 2.0 Intel order number G13326-004
