Welcome to the OCP Mezzanine NIC subgroup under OCP Server Work Group. The goal of this subgroup is to form a healthy ecosystem in Mezzanine NIC space, under OCP framework.
We are here to build a supportive, informative and inclusive community:
- Support implementation questions
- Evaluate new use cases
- Share the latest topics and trends related to OCP Mezz NIC spec
- Share both challenges and opportunities
- Take community feedback and make iterations to proposal before submitting major revision to work group and IC
- Open to both adopters, and observers

1. Updated spec draft, overview deck, and mechanical deck
1. Update spec draft to OCP_NIC_3.0_draft_0v01_20171205c_TN
2. Update pin out to OCP 3.0 Pinout Proposal 20171205a_TN
3. Specification draft complete rate (Estimation)
|Chapter||Draft complete rate||Status|
|1. Overview||70% drafted||finishing up / under review|
|2. Card form factor||60+% drafted||finishing up / under review|
|3. Card Edge and baseboard interface||80+ % drafted||Under review|
|4. Management||0% drafted||Need to work on|
|5. Data Network requirement||TBD||Same content as Mezz 2.0; check for need to keep this chapter|
|6. Card routing guideline and SI consideration||TBD||NC-SI specified on card; PCIe TBD|
|7. Thermal and Environmental||TBD||Need edit based on Mezz 2.0|
4. Key mechanical updates:
- Agreed on guiding feature and card sizes
- Reduce to 2x sizes (Small and Large form factors; detail see latest spec draft)
To be closed:
- Front bracket / latching mechanism design for small and large form factors
- Right Angle connector vertical offset(3.05mm vs. 3.50mm); Need to decide and close based on Tolerance analysis
- Straddle Mount connector offset and PCB footprint; Need to decide and close based on 1U use case study
5. Coming working sessions and proposal of agenda:
-#7 12/6 : 2hr working session; ME and EE runs in parallel; close on ME opens and clarify the rest of draft work
-#8 12/13: 3-4hr: All draft work due for 1st pass of edit of all chapters. 1st cross review with changes suggested and agreed
