What is PLDM?

PLDM (Platform Level Data Model) is a low-latency, low-complexity interface standard designed for monitoring and managing hardware components within a computing platform. It provides a standardized way for a management controller (e.g., BMC - Baseboard Management Controller) to discover, monitor, and control various devices such as sensors, fans, power supplies, and other FRUs (Field Replaceable Units). It's commonly used in server and embedded systems for hardware management and diagnostics.
