About This Manual
This is the User Guide for Ethernet NVIDIA® ConnectX®-6 Dx adapter cards for Open Compute Project Spec 3.0. These adapters' connectivity provides the highest performing low latency and most flexible interconnect solution for servers supporting OCP spec 3.0 adapter cards 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.
