PMCI Platform Management Communications Infrastructure

Working Group Description

The Platform Management Communications Infrastructure (PMCI) Working Group defines standards to address “inside the box” communication interfaces between the components of the platform management subsystem. PMCI Working Group Specifications are referenced and used by other industry organizations and specifications.

The group develops the Network Controller Sideband Interface (NC-SI), Management Component Transport Protocol (MCTP), and Platform Level Data Model (PLDM), and Security Protocol and Data Model (SPDM) specifications that provide a comprehensive, common architecture for improved communication between management subsystem components. These specifications enable the monitoring and control of systems independent of the OS state, when the OS is running or an OS is not available (for example, when a system is booting, before the OS has loaded, or when the OS is inoperable).
 
The PMCI WG creates intra-platform manageability standards and technologies, which complement DMTF’s inter-platform standards such as the Redfish API from the Redfish Forum, Common Information Model (CIM) profiles, as well as remote access protocols that are defined in the other DMTF groups.

The SPDM Specification (DSP0274) is designed to be referenced by other standards organizations and developers. SPDM incorporates the input of these external organizations, through the DMTF Alliance Partner process, to help align component authentication, confidentiality, and integrity objects across the industry.

DMTF has an assigned PCI Vendor ID of 0x1AB4 for usage with the MCTP over PCIe VDM specification.

Get Involved

  • Technical work on the NC-SI, MCTP, PLDM, and SPDM standards takes place in the Platform Management Communications Infrastructure (PMCI) Working Group.
  • DMTF members are encouraged to contribute and access the work of the PMCI Working Group via its private, members-only workspace. Non-members, learn more and join DMTF to participate.
