Product Description
NVIDIA ConnectX-7 MCX75310AAS-NEAT 400Gb/s Dual-Port Adapter
The NVIDIA ConnectX‑7 MCX75310AAS‑NEAT is a dual‑port 400Gb/s SmartNIC that supports both InfiniBand (NDR) and Ethernet (400GbE) protocols. It delivers ultra‑low latency, high throughput, and a rich set of hardware‑accelerated networking, storage, and security features. Designed for the most demanding AI, scientific computing, and hyperscale cloud workloads, ConnectX‑7 offloads critical data‑center functions from the CPU, reducing total cost of ownership while increasing performance and security.
Key Specifications

- Secure boot with hardware root‑of‑trust
Technology & Acceleration Engines
NVIDIA In‑Network Computing
ConnectX‑7 integrates collective communication offloads (SHARP), rendezvous protocol offload, and on‑board memory to accelerate MPI and deep learning frameworks. Combined with GPUDirect RDMA, data can move directly between GPU memory and the network, bypassing the CPU.
ASAP2 (Accelerated Switch and Packet Processing)
Delivers line‑rate SDN and VNF acceleration with overlay networking (VXLAN, GENEVE, NVGRE), flexible parser, connection tracking, and flow mirroring - all without CPU overhead.
Security Offloads
Hardware engines for IPsec, TLS, and MACsec with AES‑GCM 128/256‑bit keys, plus platform security (secure boot, flash encryption, device attestation).
Precision Timing
Advanced PTP (IEEE 1588v2) with 12 ns accuracy, G.8273.2 Class C, SyncE, and configurable PPS in/out, ideal for 5G, financial trading, and distributed data centers.
Typical Deployments
- AI & Deep Learning - GPU‑accelerated training and inference with GPUDirect RDMA and SHARP
- High‑Performance Computing (HPC) - MPI workloads, scientific simulations, and weather modeling
- Hyperscale Cloud - SDN, network function virtualization (NFV), and overlay networks
- Enterprise Storage - NVMe‑oF, RoCE, and GPUDirect Storage for fast data access
- Financial Services - low‑latency trading with precise PTP timing and MACsec security
