Introduction; Products Overview; Connectx-6 Dx 25Gbe Adapter Cards For Ocp 3.0 - Nvidia ConnectX-6 Dx User Manual

Introduction

This is the User Guide for Ethernet adapter cards based on the ConnectX®-6 Dx integrated circuit
device for OCP Spec 3.0. These adapters connectivity provide the highest performing low latency
and most flexible interconnect solution for servers supporting OCP 3.0 used in Enterprise Data
Centers and High-Performance Computing environments.
Important Note:
In some of the OCP 3.0 prototype samples, the insertion force that is required to install the card
into a particular PCI connector may exceed the maximum insertion force that is allowed by the
connector's spec. NVIDIA is updating the OCP 3.0 cards to ensure the proper insertion process.
The following table provides the ordering part number, port speed, number of ports, and PCI Express
speed.

Please note the following OPNs are shipped with an assembled thumbscrew (pull tab)
bracket. For other retention mechanism brackets, please contact NVIDIA.
