Introduction
This is the User Guide for Ethernet adapter cards based on the ConnectX®-6 InfiniBand/Ethernet integrated circuit device for OCP Spec 3.0. These
adapters connectivity provide the highest performing low latency and most flexible interconnect solution for PCI Express Gen 3.0/4.0 servers used in
Enterprise Data Centers and High-Performance Computing environments.
The following provides the ordering part number, port speed, number of ports, and PCI Express speed.
Important Note:
ConnectX-6 OCP 3.0 cards were tested for Shock & Vibe in accordance with NVIDIA specifications and setups as defined in document XXX, as the OCP
spec3.0 available at that time did not contain any S&V definitions. A newer version of the OCP spec 3.0 has defined S&V specifications and NVIDIA is in the
midst of retesting these cards to comply with OCP spec 3.0.
