Unified DC-SCM Pinout

Unified DC-SCM Pinout is a Workstream of the OCP Taiwan Regional Project Community. It establishes a common DC-SCM pinout profile for x86 servers, enabling plug-and-deploy interoperability across vendors and platforms. Co-developed with end customers and ecosystem partners, its standardized DC-SCM / DC-SCI pinout unifies the electrical and logical interfaces between the management module and the host system board. A single pinout specification supports cross-vendor module interchangeability and reuse across platforms and generations while reducing design complexity, lowering cost, and accelerating time to market. Proprietary implementations and platform-specific optimizations are out of scope.

About This Workstream


Workstream Lead: HsingChou Hsu

Unified DC-SCM Pinout is a Workstream of the OCP Taiwan Regional Project Community, which discusses OCP Technology and Vertical Projects as they apply across Taiwan and serves as the feedback loop between the Taiwanese supply chain and global data center innovators.

The workstream establishes a common DC-SCM pinout profile for x86 servers, enabling plug-and-deploy interoperability across vendors and platforms. It delivers a standardized DC-SCM / DC-SCI pinout, co-developed with end customers and ecosystem partners, to unify the electrical and logical interfaces between the management module and the host system board.

By adopting a single pinout specification, the initiative supports dependable cross-vendor module interchangeability while reducing design complexity, lowering cost, and accelerating time to market. The work is focused on open interface standardization and ecosystem interoperability, avoiding proprietary implementations and platform-specific optimizations.

Scope

The workstream focuses on open interface standardization and ecosystem interoperability across four areas:

Unified DC-SCM / DC-SCI Pinout Definition — an updated DC-SCM SCI specification defining a compliant, standardized electrical and logical interface between the management module and the system board; a minimum deterministic power, reset, and strap signal profile for cross-vendor interoperability on x86-based servers; and validation of the unified pinout on x86 platforms
Platform Interoperability and Module Reuse — a consistent, reusable DC-SCM interface that lets modules be reused across server platforms and generations, eliminating repeated management-subsystem redesigns and enabling second-source strategies
Ecosystem Collaboration and Validation — validating electrical and functional interoperability of the unified pinout with end customers and ecosystem partners, including module reuse across platforms and platform-level validation for broad adoption within the OCP ecosystem
Data Center Efficiency Enablement — reducing system development time, cost, and complexity; improving supply chain efficiency and long-term sustainability through module reuse and standardization; and accelerating integration and time to market for data center deployments

Out of scope

  • Proprietary or vendor-specific DC-SCM implementations
  • Firmware, BMC feature definition, or security policy specification
  • Mechanical form factors or chassis-level design requirements
  • Compliance, certification, or manufacturing processes
  • Component-level redesign beyond the defined DC-SCM / DC-SCI interface
