NVIDIA ConnectX-7 MCX755106AS-HEAT 400Gb/s Dual-Port InfiniBand & Ethernet Smart NIC
The industry-leading 400Gb/s RDMA adapter for AI, scientific computing, and hyperscale cloud data centers.
NVIDIA ConnectX-7 MCX755106AS-HEAT is a dual-port, 400Gb/s network adapter supporting both InfiniBand (NDR/HDR/EDR) and Ethernet (400/200/100/50/25/10GbE) protocols. Featuring PCIe Gen5 x32 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 the world's most demanding workloads.
Product Overview
The NVIDIA ConnectX-7 MCX755106AS-HEAT is a dual-port, 400Gb/s RDMA network adapter that supports both InfiniBand and Ethernet protocols. It is designed to address the full spectrum of networking needs—from traditional enterprise IT infrastructure to the most demanding AI, scientific computing, and hyperscale cloud data center environments.
Leveraging PCIe Gen5 host connectivity with up to 32 lanes, the MCX755106AS-HEAT delivers extreme throughput and ultra-low latency. It integrates NVIDIA's in-network computing engines, including SHARP collective offloads, GPUDirect RDMA, and GPUDirect Storage, to accelerate data movement and reduce CPU overhead. Built-in hardware security engines provide in-line encryption for IPsec, MACsec, and TLS, ensuring end-to-end data protection without performance penalty.
