3. [http://files.opencompute.org/oc/public.php?service=files&t=399a90213e5fe9004c79e7bd0be5041e Schedule proposal v01] is available for review and comment. A few notes:
4. Key mechanical updates:  


- Overall it includes 3x stages: Information collection => Narrow down direction => work out details and 1st draft
- Agreed on guiding feature and card sizes


- The v01 schedule is on the aggressive side, i.e. the best case scenario when everything goes as expected.
- Reduce to 2x sizes (Small and Large form factors; detail see latest spec draft)


- Please review it, give inputs in mailing-list, and discuss in the call next week.
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


'''3/24/2017'''
- Straddle Mount connector offset and PCB footprint; Need to decide and close based on 1U use case study


An [http://files.opencompute.org/oc/public.php?service=files&t=4baf98af7f736844e149508321370650 improved version of survey template v02] is created.
All NIC suppliers are strongly recommend to participate to influence Mezz 3.0.
Inputs from System supplier and Hyper-scale/CSP are welcome as well.


Agenda for next meeting (4/5)
5. Coming working sessions and proposal of agenda:


1. Review overall Mezz 3.0 work schedule
-#7 12/6 : 2hr working session; ME and EE runs in parallel; close on ME opens and clarify the rest of draft work


2. Review the boundary with the context of major options

Revision as of 07:24, 19 January 2018

Welcome

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.

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
