Platform Level Data Model (PLDM): A Technical Overview

Hemal Shah, Broadcom Corporation

The Platform Level Data Model (PLDM) is being designed by the DMTF Platform Management Component Intercommunications (PMCI) Workgroup to be an effective data and control source for mapping under CIM. PLDM is targeted for efficient communications among platform management subsystem components for accessing low-level platform inventory, monitoring, control, eventing, and data/parameters transfer functions including SMBIOS data transfer and BIOS control/configuration. PLDM is used to define data representations and commands that abstract the platform management hardware. This talk will provide a technical overview of PLDM and describe how PLDM can be used for intercommunications among platform management subsystem components to transfer management data and perform management functions.

Platform Level Data Models for SMBIOS Data Transfer and BIOS Control/Configuration

Hemal Shah, Broadcom Corporation

This talk is a more detailed follow on to the previous talk on PLDM: A Technical Overview. This talk will describe the Platform Level Data Model (PLDM) data structures and commands for transferring SMBIOS data and for communicating BIOS settings, BIOS attributes, boot configurations, and boot order settings. The SMBIOS specification defines BIOS extensions that provide platform asset information such as BIOS version, processor speed/type, and memory capacity. The BIOS management and boot control CIM profiles define the remote management aspects of the BIOS configuration and control. A management controller that is exposing the remote management aspects of the BIOS performs internal platform communications with the BIOS to exchange the BIOS configuration and control related data.

Platform Level Data Model for Platform Monitoring and Control

Tom Slaight, Intel Corporation

This talk is a more detailed follow on to the previous talk on PLDM: A technical overview. The Platform Level Data Model (PLDM) for Platform Monitoring and Control defines messages and data structures for discovering, describing, initializing, and accessing sensors and effecters within management controllers and management devices of a platform management subsystem. The PLDM for Platform Monitoring and Control additionally defines functions related to platform monitoring and control, such as the generation and logging of platform level events. PLDM state sets define a set of enumeration values that reflect managed platform’s states. The PLDM state sets are used for PLDM sensors and effecters. This talk will provide a detailed technical overview of the PLDM for Platform Monitoring and Control and PLDM state sets.
