Introduction - Nvidia MCX545B-CCUN User Manual

Introduction

This is the User Guide for Ethernet adapter cards based on the ConnectX®-5 integrated circuit device
for OCP Spec 2.0. 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.

a. PCIe 4.0 x16 bus can supply a maximum bandwidth of 256Gb/s (=16 *16GT/s, including overhead),
and can support 200Gb/s when both network ports of the card run at 100Gb/s.
b. The Gen4.0 cards have been tested and certified with PCIe 3.0 servers. PCIe 4.0 interface will be
tested when servers with Gen 4.0 support become available.
