Introduction - Nvidia ConnectX-5 User Manual

Introduction

This is the User Guide for Ethernet adapter cards based on the ConnectX®-5 and ConnectX®-5 Ex
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.
Important Notes:
1. ConnectX-5 OCP 3.0 cards were tested for Shock & Vibe in accordance with NVIDIA
specifications and setup, 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 A newer version of the OCP spec 3.0 has defined S&V specifications and NVIDIA is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.
2. In some of the OCP 3.0 cards, 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 tables provide the ordering part number, port speed, number of ports, and PCI Express
speed per ConnectX-5 and ConnectX-5 Ex OPNs.
