Server/DC-MHS

Welcome

Welcome to the OCP DC-MHS Sub-Project.

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 seven workstreams that comprise DC-MHS:

• M-FLW (FulL Width HPM)
• M-DNO (DeNsity Optimized HPM)
• M-XIO (eXtended I/O Connectivity)
• M-PIC (Platform Infrastructure Connectivity)
• M-CRPS (Common Redundant Power Supply)
• M-PESTI (PEripheral SideBand Tunneling Interface)
• M-SIF (Shared InFrastructure)

All presentation materials, proposals, meeting minutes and/or supporting documents are published by OCP and are open to the public in accordance with OCP's Bylaws and IP Policy.
