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

  • M-FLW (FulL Width HPM)
    • Specify the requirements of a Full Width Host Processor Module (HPM). This is for use within products designed for minimum 19" rack, also known as compliant with EIA-310-E but can also accommodate larger 21" racks. This form factor enables a full width HPM usage for CPUs, DIMMs, and related features.
  • M-DNO (DeNsity Optimized HPM)
    • Outline the requirements of a family of partial width, DeNsity Optimized Host Processor Module (HPM) form factors within the OCP Modular 240 hardware system group of specifications (M-DNO for short). This M-DNO specification embodies design considerations for CPU, DIMMs, and other server processor related features commonly used by the industry today but is not limited to only those functions.
  • M-XIO/PESTI ( (eXtended I/O Connectivity/PEripheral SideBand Tunneling Interface) :
    • Outline the Modular Extensible I/O (M-XIO) source connector hardware strategy. An M-XIO source connector enables entry and exit points between sources such as Motherboards, Host Processor Modules & RAID Controllers, and peripheral subsystems such as PCIe risers, backplanes, etc. M-XIO includes the connector, high speed and management signal interface details and supported pinouts. Additionally, the workstream defines Interface (M-PESTI) base requirements for electrical and protocol compatibility between components of a DC-MHS platform. The M-PESTI protocol overloads a common PRSNT# signal with additional capabilities beyond simple presence/absence of a peripheral.
  • M-PIC (Platform Infrastructure Connectivity)
    • Defines and standardizes common elements needed to interface a Host Processor Module (HPM) to the platform/chassis infrastructure elements/subsystems within the DC-MHS 1.0 family of OCP servers. Standardization of the common interfaces and connectors enables hardware compatibility between DC-MHS HPMs and various DC-MHS system components.
  • M-CRPS (Common Redundant Power Supply)
    • Defines all the requirements for an M-CRPS internal redundant power supply used in Open Compute Project that could be used in different environments like home/office, datacenter, and high-performance computing, hence harmonizing the server power supply requirements used in the industry with the purpose of creating a standard specification that the customers and vendors of Enterprise and Hyperscale can use for their products.
  • M-SIF (Shared InFrastructure)
    • Improve interoperability related to shared infrastructure enclosures with multiple, serviceable modules. Modules containing elements (HPMs, DC-SCM, peripherals, etc.) are blind-matable and hot-pluggable into a shared infrastructure enclosure.
