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
