NVIDIA ConnectX-7 NDR 400Gb/s InfiniBand Smart Adapter MCX75310AAS-HEAT | 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. ✓ PCIe 5.0 x16 ✓ RoCE & InfiniBand ✓ Secure Boot + IPsec/TLS/MACsec inline ✓ SHARPv3 collective offloads 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-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. Key Features Ultra-high throughput Dual-port NDR 400Gb/s InfiniBand or 400GbE, PCIe Gen5 x16 (up to 32 lanes). In‑Network Computing SHARPv3 collective operations offload, rendezvous protocol offload, on‑board memory for bursts. Hardware Security Engines Inline IPsec/TLS/MACsec AES-GCM 128/256-bit, secure boot with hardware root-of-trust, flash encryption. Precision Timing IEEE 1588v2 PTP (12ns accuracy), SyncE, class C G.8273.2, time-triggered pacing. Accelerated Storage & GPUDirect GPUDirect RDMA, GPUDirect Storage, NVMe‑oF offload, T10-DIF signature handover. SDN & Overlay offloads VXLAN, GENEVE, NVGRE, programmable flexible parser, connection tracking (L4 firewall). 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: 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.

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. ConnectX-7 supports both via dual personality. 2. Is the MCX75310AAS-HEAT 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. 3. Does this model support Multi‑Host? Yes, ConnectX-7 supports NVIDIA Multi-Host technology, allowing up to 4 independent hosts to share the same adapter (specific SKU and cabling dependent). Please confirm with ordering guide. 4. What encryption standards are accelerated inline? IPsec (AES-GCM 128/256-bit), TLS (AES-GCM 128/256-bit), and MACsec (AES-GCM 128/256-bit). All offloaded from CPU. 5. Can I use this adapter for NVMe/TCP acceleration? Absolutely. ConnectX-7 offloads NVMe over TCP as well as NVMe‑oF, reducing host CPU overhead for storage. Precautions & Installation Notes
