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

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
-#9 12/20: 3-4hr: Review changes and post 1st draft
