Product Description
NVIDIA ConnectX-7 NDR 400Gb/s Smart NIC
MCX75310AAS-NEAT | PCIe Gen5 Dual-Port 400GbE / NDR
Ultra-low latency RDMA networking for AI factories, HPC clusters, and hyperscale cloud. Supports InfiniBand NDR (400Gb/s) and Ethernet up to 400GbE. In-Network Computing engines, hardware security acceleration, and GPUDirect Storage ready.
Product Overview
The NVIDIA ConnectX-7 family redefines data center interconnectivity with up to 400Gb/s bandwidth, hardware-based reliable transport, and advanced in-network computing. The model MCX75310AAS-NEAT belongs to the ConnectX-7 VPI adapter series supporting both InfiniBand (NDR/HDR/EDR) and Ethernet (400GbE to 10GbE). Built for AI, scientific computing, and modern software-defined storage, it delivers sub-microsecond latency and frees CPU cores via acceleration engines for security, virtualization, and NVMe-oF.
Key Features
- Ultra-high throughput: Dual-port NDR 400Gb/s InfiniBand or 400GbE, PCIe Gen5 x16
- In-Network Computing: SHARPv3 collective operations offload, rendezvous protocol offload
- Hardware Security Engines: Inline IPsec/TLS/MACsec AES-GCM 128/256-bit, secure boot
- Precision Timing: IEEE 1588v2 PTP (12ns accuracy), SyncE, time-triggered scheduling
- Accelerated Storage and GPUDirect: GPUDirect RDMA, GPUDirect Storage, NVMe-oF offload
- SDN and Overlay Offloads: VXLAN, GENEVE, NVGRE, programmable flexible parser
Technology – Built for Data-Driven Acceleration
NVIDIA ASAP² (Accelerated Switch and Packet Processing) offloads entire data paths, delivering line-rate SDN performance with zero CPU overhead. ConnectX-7 integrates advanced memory virtualization and supports SR-IOV, VirtIO acceleration, and Multi-Host technology for bare-metal performance in virtualized environments.
Typical Deployments
- AI and Large Language Model clusters
- High-Performance Computing (HPC)
- Cloud and Edge data centers
- Software-defined storage (SDS)
- Real-time analytics and trading

Frequently Asked Questions
What is the primary difference between NDR InfiniBand and 400GbE mode?
NDR includes advanced in-network computing features like SHARP, adaptive routing, and hardware reliable transport natively; Ethernet mode uses RoCE for RDMA with the same line rate.
Is the MCX75310AAS-NEAT compatible with PCIe Gen4 motherboards?
Yes, the adapter is backward compatible with PCIe Gen4 and Gen3, but at reduced lane speed. Best performance is achieved on PCIe Gen5 slots.
