This enables a developement +platform for software development. + +For connection with a DC-SCM, the DC-SCM v1.0 release design specifies the connector as an SFF-TA-1002 compliant 4C+ connector. The 4C+ connector is a 4C compliant connector with an additional 28-pin “OCP bay” defined in the OCP NIC 3.0 specification. The right-angled variety allows for the DC-SCM to lay within the BMC cage assembly. This can be implemented with TE 2336568-1. + +References: + +DC-SCM 0.95 Draft Specification: +https://www.opencompute.org/documents/ocp-dc-scm-spec-rev-0-95-pdf + +DC-SCM 2.0 Draft Specification: +https://drive.google.com/file/d/1UkFgAFKh8qz4mAXdvodYsW0fg8XhyVf2/view?usp=sharing + +AC922 Specification: +see OpenPower website + +SFF-TA-1002 Protocol Agnostic Multi-Lane High Speed Connector +https://members.snia.org/document/dl/27231 + +AntMicro Design Specification: +https://github.com/antmicro/artix-dc-scm.git
