Comprehensive Product Overview

The MCX75310AAS-NEAT is a flagship NVIDIA Mellanox ConnectX-7 smart network adapter designed for next-generation 400G high-speed networking. Equipped with one OSFP pluggable interface, it supports wire-speed 400Gb/s NDR InfiniBand and 400GbE Ethernet via flexible VPI technology, automatically adapting to InfiniBand or Ethernet fabric.

Leveraging PCIe 5.0 x16 32GT/s bandwidth, the adapter provides full line-rate performance without bottlenecks for high-throughput and latency-sensitive workloads. It integrates advanced hardware acceleration engines including RDMA over InfiniBand and RoCEv2, GPU Direct RDMA, NVMe-oF offload, and collective computation acceleration to drastically reduce CPU overhead.

The card comes with full-height and low-profile brackets, supporting standard rack server deployment. With robust enterprise-grade reliability, secure boot, hardware encryption and wide temperature tolerance, MCX75310AAS-NEAT is perfectly suited for 24/7 mission-critical AI, HPC, cloud and storage infrastructures.
