Nvidia ConnectX-6 Dx User Manual

9
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.
