Server/NIC

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
