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)
===Archive===


To be closed:
[http://www.opencompute.org/wiki/Server/Mezz/Update_Archive '''Find Archive of updates here''']
 
- 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
 
 
'''11/20 update'''
 
1. Updated specification(11/12) and pin definition(11/15) to the "updated doc session"; The spec still needs a lot of work in the coming a few weeks.
 
2. Thermal deck v7 is uploaded (same material as presented on 11/15)
 
 
'''10/31 update'''
 
1. We did 4x working session so far and made good progress in pinout and mechanical profile
 
- 10/11 11:30am-3pm(PDT) - Done: TE/Dell-EMC/Intel/FB
 
- 10/18 9am-2pm(PDT) - Done: TE/Dell-EMC/Lenovo/Broadcom/Intel/FB
 
- 10/27 8am - 11am(PDT)  Done: – TE/Dell-EMC/Lenovo/Broadcom/Intel/FB
 
- 10/31 8:30am - 10am(PDT) Done: - (Pinout specific session) Mellanox / Broadcom / Intel / Dell-EMC / FB
 
- 11/3 8am-11am(PDT)
 
- 11/15 9am-5pm(PST)
 
2. Latest pin out and ME deck are posted at [http://www.opencompute.org/wiki/Server/Mezz#Updated_doc Table above]
 
3. Plan to post WIP specification draft after 11/3 workshop for broader review
 
4. We will cancel the 2017/11/01 meeting as FB team has a conflict
 
 
 
'''10/18 Update'''
 
- Intel/Dell-EMC/TE/FB joined the spec drafting working session on 10/11 and worked on these topics: [http://files.opencompute.org/oc/public.php?service=files&t=089dc36e019eadfcbdc590837e7e0dc6 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 [http://files.opencompute.org/oc/public.php?service=files&t=520161aaf734e0b8690a9003b73bd57c 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 [http://files.opencompute.org/oc/public.php?service=files&t=aa9736b73845229c4dcd6cf47c74296e [here]]

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

- Damien Chong (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
