2. Update pin out to OCP 3.0 Pinout Proposal 20171205a_TN

3. Specification draft complete rate (Estimation)

Chapter Draft complete rate Status

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

10/18 Update

- Intel/Dell-EMC/TE/FB joined the spec drafting working session on 10/11 and worked on these topics: framework, sections, pinout, connector, specification drafting logistics.

- With many inputs from community, FB updated Mechanical deck to v3; Key changes are 1) fine tuning module width by 2mm 2) proposing 1 extra sizes, and total 3x sizes with different width. Detail see Mechanical Discussion_v03_20171018

- Pinout is being actively working on. Intel is taking lead on proposing and maintaining the draft; an updated version can be found [here]

- We will move from Fuze to GoToWebinar for project calls in Nov. 10/18 call is likely the last call on Fuze. More details to follow in mailing list and calendar.


9/20 Update

- The subgroup closed on all other major options after a few months of iterations. #14 is the clear preference in subgroup. Details and specification will be worked out around this option.

- Update mechanical 3D package to r02

- Update mechanical deck to r02


9/6 Update

- Add updated doc session for better tracking of latest docs and community presentations

- Update general deck to v9, thermal deck to v6

- Intend to exit phase 2 by 9/20 with option #14

- Change project name from "OCP Mezz NIC 3.0" to "OCP NIC 3.0" as option #14 is not Mezz style
