OCP-Open-compute-NIC-3-v2-1x-v1-42a.png

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

For more information, please contact Jia Ning (Facebook)


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

Get Involved

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

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