NVIDIA ConnectX‑7 400G InfiniBand Adapter MCX75310AAS‑NEAT
NVIDIA Mellanox ConnectX-7 MCX75310AAS-NEAT 400Gb/s NDR InfiniBand Smart Network Adapter engineered for AI factories, scientific computing, and hyperscale cloud. Delivers 400Gb/s throughput, sub-microsecond latency, and hardware-accelerated inline security (IPsec/TLS/MACsec). Supports PCIe Gen5 x16, GPUDirect RDMA, and advanced in-network computing offloads.
Product Overview
The NVIDIA ConnectX-7 family represents a breakthrough in RDMA networking, supporting both InfiniBand and Ethernet protocols up to 400Gb/s. The MCX75310AAS-NEAT model is a high-density single-port NDR InfiniBand adapter designed for demanding HPC and AI clusters. It integrates PCIe Gen5 host interface, hardware offloads for NVMe-oF, collective communications (SHARP), and inline encryption engines, enabling secure, ultra-efficient data centers with lower TCO.
Key Hardware & Performance
- NDR InfiniBand 400Gb/s (compatible with HDR 200G/EDR 100G)
- PCI Express Gen5.0 x16 (supports bifurcation up to x32 lanes)
- Ultra-low latency & hardware-based reliable transport
- GPUDirect RDMA & GPUDirect Storage for GPU-accelerated workloads
- In-Network Computing: SHARPv3 collective offloads
Security & Offload Engines
- Inline IPsec, TLS, MACsec encryption/decryption (AES-GCM 128/256-bit)
- Secure boot with hardware root-of-trust & flash encryption
- ASAP2 (Accelerated Switch and Packet Processing) for SDN
- Connection tracking, flow mirroring, and header rewrite
- Zero-Touch RoCE and overlay network acceleration (VXLAN, GENEVE)
Advanced Technology Accelerators
The ConnectX-7 MCX75310AAS-NEAT incorporates NVIDIA's latest in-network computing engines, offloading critical data path tasks from the CPU:
- RDMA & RoCE: Zero-copy data movement, NVMe-oF offloads (including NVMe/TCP), iSER, SRP, and NFS over RDMA
- Timing & Synchronization: IEEE 1588v2 PTP with 12ns accuracy, SyncE, time-triggered scheduling, PPS input/output
- Virtualization & Multi-Host: SR-IOV, VirtIO acceleration, and NVIDIA Multi-Host technology supporting up to 4 independent hosts
- Data Integrity: T10-DIF signature handover, block-level XTS-AES 256/512 encryption, advanced error reporting (AER)
Typical Deployments & Use Cases
AI & Deep Learning Clusters: Large-scale GPU clusters requiring GPUDirect RDMA and SHARP offloads for NCCL/UCC acceleration.
HPC & Scientific Computing: Weather modeling, molecular dynamics, genome research with MPI libraries and adaptive routing.
Hyperscale Cloud & SDDC: Overlay networking, VXLAN offload, and ASAP2 flow processing for software-defined data centers.

Selection Guide: ConnectX-7 Family
When selecting the MCX75310AAS-NEAT, consider port speed (NDR), host slot (PCIe Gen5 x16) and form factor (HHHL). For dual-port or OCP 3.0 requirements, refer to the full ConnectX-7 portfolio:
- Single-port NDR HHHL: MCX75310AAS-NEAT (ideal for GPU servers with limited slots)
- Dual-port NDR / 400G: Check MCX75310AAS-HEAT (confirm ordering guide)
- OCP 3.0 SFF adapter: For rack scale designs
Note: Always verify MPN and firmware region before ordering; datasheet available via NVIDIA docs.nvidia.com/networking
Why Choose MCX75310AAS-NEAT?
Superior TCO: Offloads CPU from networking, security, and storage tasks; reduces server overhead.
Future-ready PCIe Gen5: Doubles bandwidth over Gen4, ideal for next-gen compute nodes.
Zero Trust Security: Line-rate inline crypto with no performance penalty, secure boot ensures infrastructure integrity.
In-network Acceleration: SHARPv3 collective operations reduce MPI traffic, accelerate job completion time.
