Introduction

Product Overview

The NVIDIA ConnectX-7 family of network adapters supports both the InfiniBand and Ethernet
protocols. It enables a wide range of smart, scalable, and feature-rich networking solutions that
address traditional enterprise needs up to the world's most demanding AI, scientific computing, and
hyperscale cloud data center workloads.
ConnectX-7 network adapters are offered in two form factors and various flavors: stand-up PCIe and
Open Compute Project (OCP) Spec 3.0 cards. This user manual covers the PCIe stand-up cards, for
the OCP 3.0 cards, please refer to

Make sure to use a PCIe slot capable of supplying the required power and airflow to the
ConnectX-7, as stated in the
PCIe x16 Stand-up Adapter Cards
ConnectX-7 HCAs are available in various configurations; Single-port 400Gb/s or 200Gb/s, with octal
small form-factor pluggable (OSFP) connectors or Dual-port 100 or 200Gb/s with quad small form-
factor pluggable (QSFP112) connectors on PCIe standup half-height, half-length (HHHL) form factor,
with options for NVIDIA Socket Direct. Also available, Dual-port 50/25 GbE with quad small form-
factor pluggable (SFP56) connectors on PCIe standup full-height, half-length (FHHL) form factor,
with timing capabilities.
ConnectX-7 cards can either support both InfiniBand and Ethernet, or Ethernet only, as described in
the below table. The inclusive list of OPNs is available here.

Socket Direct Ready Cards

The Socket Direct technology offers improved performance to dual-socket servers by enabling direct
access from each CPU in a dual-socket server to the network through its dedicated PCIe interface.
NVIDIA offers ConnectX-7 Socket Direct adapter cards, which enable 400Gb/s or 200Gb/s
connectivity, and also for servers with PCIe Gen 4.0 capability. The adapter's 32-lane PCIe bus is
split into two 16-lane buses, with one bus accessible through a PCIe x16 edge connector and the
other bus through an x16 Auxiliary PCIe Connection card. The two cards should be installed into two
PCIe x16 slots and connected using two Cabline SA-II Plus harnesses.
To use this card in the Socket-Direct configuration, please order the additional PCIe Auxiliary Card
kit according to the desired harness length. Cards that support socket direct can function as
separate x16 PCIe cards.
