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.
We are here to build a supportive, informative and inclusive community:
- Support implementation questions
- Evaluate new use cases
- Share the latest topics and trends related to OCP Mezz NIC spec
- Share both challenges and opportunities
- Take community feedback and make iterations to proposal before submitting major revision to work group and IC
- Open to both adopters, and observers
See below for material for tomorrow's call:
1. Review latest round of simulation results
2. Go over a few topics for discussion
See below for material for tomorrow's call:
1. Review changes to thermal models based on feedback from the community
2. Review latest round of simulation results
3. Go over a few topics for discussion
Here are the update in the past 2x weeks, and material for tomorrow's call:
Additional questions to NIC suppliers:
- Standby(S5) power of NIC, or ratio of P_Standby / P_Max
- P_standby of Optical modules
As we kicked off the discussion of Mezz thermal simulation on 4/19, here are the updates:
Please give your feedback in mailing list and we will talk about it on next call on 5/3.
We have an updated schedule for comment and feedback:
Mezz 3.0 Survey is closed with 5 participants; Summary with company names masked can be found here:

1. Sync with community about schedule refresher and get feedback for schedule and milestone
2. Summary of survey
3. John Fernandes will share methodology for thermal simulation
4. Call for more feedback on a few options (9,10,11,12)
1. Ramp NIC survey template version to v03 to have more exact wording. Template v03
2. Due to the limitation of mailing-list with attachment, please send the filled template to email@example.com. Jia will aggregate and update to the wiki based on your selection of the confidential level (cell B6,B7 of the template v03)
3. Schedule proposal v01 is available for review and comment. A few notes:
- Overall it includes 3x stages: Information collection => Narrow down direction => work out details and 1st draft
- The v01 schedule is on the aggressive side, i.e. the best case scenario when everything goes as expected.
- Please review it, give inputs in mailing-list, and discuss in the call next week.
An 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)
1. Review overall Mezz 3.0 work schedule
2. Review the boundary with the context of major options
3. Pick major option branches to perform more detailed study
A survey of boundary condition of typical use cases is going on.
