NVIDIA ConnectX-7 NDR 400Gb/s InfiniBand Adapter MCX75310AAS-HEAT | PCIe Gen5 Dual-Port

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.

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-HEAT 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. With PCIe Gen5 host interface, this adapter maximizes data movement for GPU clusters and high‑frequency trading environments.

Leveraging ASAP² (Accelerated Switch and Packet Processing) and Zero-Touch RoCE, the adapter simplifies deployment while providing inline hardware encryption – from edge to core. Enterprises can future-proof their infrastructure with NDR speeds and flexible multi‑host support.

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: On‑Demand Paging (ODP), User Mode Registration (UMR), and address translation services (ATS) for efficient containerized workloads. With support for SR-IOV, VirtIO acceleration, and Multi‑Host technology (up to 4 hosts), the adapter enables bare‑metal performance in virtualized environments. The hardware RoCE engine ensures zero‑touch deployment for converged Ethernet fabrics, while the in‑network memory reduces latency for MPI and collective communication libraries (NVIDIA HPC-X, UCX, NCCL).

To address security from edge to core, inline cryptography engines handle IPsec, TLS 1.3, and MACsec without consuming execution cores, making it ideal for multi‑tenant clouds and financial services.

• AI & Large Language Model clusters: RDMA & GPUDirect accelerating distributed training across hundreds of GPUs.
• High‑Performance Computing (HPC): MPI offloads, SHARPv3 for in‑network reduction, adaptive routing.
