Product Description
The NVIDIA Mellanox ConnectX-7 MCX75510AAS-NEAT is a single-port 400Gb/s InfiniBand NDR smart adapter in a standard stand-up PCIe form factor that is Socket Direct ready, allowing an optional auxiliary card to split its PCIe lanes across two CPU sockets on supported dual-socket platforms. The OSFP port delivers native InfiniBand NDR connectivity at up to 400Gb/s, with RoCE v2 support available for RDMA over Ethernet fabrics when needed. Installed through a PCIe 5.0 x16 host interface, the MCX75510AAS-NEAT carries ConnectX-7's full RDMA stack - native InfiniBand transport with SHARP in-network computing acceleration - together with hardware-enforced Secure Boot to protect firmware integrity against tampering. GPUDirect RDMA support enables direct GPU-to-NIC data transfers for AI/ML and HPC workloads, while adaptive routing and advanced congestion control sustain high throughput and low tail latency across large, multi-path InfiniBand fabrics - making the card well suited to dedicated HPC and AI clusters built around native InfiniBand.
