The Data Center - Modular Hardware System (DC-MHS) Sub-Project is under the direction of the OCP Server Project Group.


DC-MHS R1 envisions interoperability between key elements of datacenter, edge and enterprise infrastructure by providing consistent interfaces and form factors among modular building blocks.

DC-MHS R1 standardizes a collection of HPM (Host Processor Modules) form-factors and supporting ingredients to allow interoperability of HPMs and platforms.

There are five workstreams that comprise DC-MHS. The objectives of the five workstreams are the following:

  • M-HPM (Host Processor Modules) Workstream which involves three specifications:
    • M-FLW (FulL Width HPM)
    • M-DNO (DeNsity Optimized HPM)
    • (Next HPM form factors under consideration)
  • M-XIO/PESTI (eXtended I/O Connectivity/Peripheral SideBand Tunneling Interface)
  • M-PIC (Platform Infrastructure Connectivity)
  • M-CRPS (Common Redundant Power Supply)
  • M-SIF (Shared InFrastructure)

Call Calendar

Monthly DC-MHS public calls will begin on March 15th 2023.
The public call schedule is the 3rd Wednesday of the Month at 0800 PST.
