Product Description
NVIDIA ConnectX-7 MCX75310AAS-NEAT 400G Single-Port RDMA Adapter
High-performance 400Gb/s RDMA adapter designed for AI, scientific computing, and hyperscale cloud data centers.
Product Overview
The NVIDIA ConnectX-7 MCX75310AAS-NEAT is a single-port, 400Gb/s network adapter supporting both InfiniBand (NDR/HDR/EDR) and Ethernet (400/200/100/50/25/10GbE) protocols. Featuring PCIe Gen5 x16 host interface, GPUDirect RDMA and Storage, in-line encryption (IPsec, MACsec, TLS), SHARP in-network computing, and advanced timing (PTP Class C, SyncE), it delivers ultra-low latency and extreme throughput for demanding workloads.
