NVIDIA ConnectX-7 MCX75310AAS-NEAT NDR 400Gb/s InfiniBand Adapter

The NVIDIA ConnectX-7 MCX75310AAS-NEAT is a flagship NDR 400Gb/s InfiniBand Smart Adapter featuring PCIe Gen5 x16 interface for both InfiniBand and RoCE. Engineered for AI factories, HPC clusters, and hyperscale cloud data centers, this ultra-low latency adapter integrates in-network computing, hardware security offloads, and advanced virtualization to accelerate modern scientific computing and software-defined infrastructures.

The NVIDIA ConnectX-7 family delivers groundbreaking performance with up to 400Gb/s bandwidth per port, supporting both InfiniBand (NDR/HDR/EDR) and Ethernet (up to 400GbE). Model MCX75310AAS-NEAT features PCIe Gen5 host interface (up to x32 lanes), multi-host capability, and advanced engines for GPUDirect RDMA, NVMe-oF acceleration, and inline cryptography. Built for demanding AI training, simulation, and real-time analytics, this adapter reduces CPU overhead while maximizing data throughput and security.

With on-board memory for rendezvous offload, SHARP collective acceleration, and ASAP2 SDN offloads, ConnectX-7 transforms standard servers into high-performance network nodes with near-zero jitter and nanosecond-precision timing (IEEE 1588v2 Class C).

Built on 7nm process, ConnectX-7 integrates multiple hardware acceleration engines that offload the CPU and deliver deterministic performance. Key technological pillars include:

Operating Systems & Virtualization: In-box drivers for Linux (RHEL, Ubuntu, Rocky Linux), Windows Server, VMware ESXi (SR-IOV), and Kubernetes (CNI plugins). Optimized for NVIDIA HPC-X, UCX, OpenMPI, MVAPICH, MPICH, OpenSHMEM, NCCL, and UCC.

Hardware Compatibility: Standard PCIe Gen5 slots (x16 mechanical, x16/x32 electrical). Certified with major server platforms from HPE, Supermicro, and NVIDIA DGX systems.

Interoperability: Fully compliant with InfiniBand Trade Association Spec 1.5, IEEE 802.3 for Ethernet, and PCI-SIG Gen5 specifications.
