Advancing PLDM - Structured Sensors, Scalable Modeling, and the Server Host SoC PLDM Specification

Explore the latest developments in Platform Level Data Model (PLDM) technology through this 17-minute conference talk from the Open Compute Project. Learn about the challenges facing existing PLDM mechanisms as server platforms become increasingly complex with more cores, memory controllers, accelerators, and sensors. Discover early DMTF work to extend PLDM with enhanced capabilities including Structured PLDM Sensors, Scalable Entity Association PDRs, and Clone PDRs that address current limitations in system description and management. Examine a new DMTF informational specification for modeling Server Host SoCs that leverages these extensions to define sensors and effecters across various SoC subsystems including cores, memory, PCIe, and networking components. Understand how these innovations aim to improve interoperability, enable structured data representation, and enhance manageability for complex and modular systems. Gain insights into current work-in-progress from the DMTF PMCI working group and learn how the OCP community can contribute to aligning future server design and firmware implementations with these advancing standards.
