Extended Connectivity Requirements

Extended Connectivity Requirements is a Workstream under the Composable Memory System (CMS) Sub-Project of the OCP Server Project. It documents industry usage-model scenarios and requirements for rack-level disaggregated NVMe and/or CXL interconnected compute, acceleration, memory, and storage modules using PCIe Gen5 and Gen6 external Direct Attached (DAC), Active Electrical (AEC), and Active Optical (AOC) cables. The workstream does not explore specific implementation solutions; a future industry standards committee is expected to turn its requirements into a complete standard cabling specification.

Extended Connectivity Requirements is a Workstream under the Composable Memory System (CMS) Sub-Project of the OCP Server Project.

The Composable Memory System (CMS) Sub-Project sits under the OCP Server Project. It was created when the OCP Future Technologies Initiative’s Software Defined Memory workstream transitioned into a new OCP Sub-Project, now called Composable Memory Systems.

The workstream documents the various industry usage-model scenarios and requirements for rack-level disaggregated NVMe and/or CXL interconnected compute, acceleration, memory, and storage modules using PCIe Gen5 and Gen6 external Direct Attached (DAC), Active Electrical (AEC), and Active Optical (AOC) cables.

The workstream will not explore any specific implementation solutions at this time; however, a future industry standards committee will be formed by willing members aiming to materialize the requirement output of this workstream into a complete standard cabling specification.

Scope

The workstream’s scope covers:

Usage models and requirements — documenting industry usage-model scenarios and requirements for rack-level disaggregated interconnect
Disaggregated modules — NVMe and/or CXL interconnected compute, acceleration, memory, and storage modules
External cabling — PCIe Gen5 and Gen6 Direct Attached (DAC), Active Electrical (AEC), and Active Optical (AOC) cables
Out of scope — specific implementation solutions; a future standards committee will turn the requirements into a complete cabling specification
