Product Description
The NVIDIA Mellanox ConnectX-7 MCX75343AMS-NEAC is a single-port 400Gb/s VPI smart adapter built in the OCP 3.0 Small Form Factor, delivering NVIDIA's fastest ConnectX-7 port speed in a hyperscale-ready package. The QSFP port ships in InfiniBand NDR default mode at 400Gb/s and can also run 400GbE Ethernet, giving data center operators a single SKU for either fabric. Through a PCIe 5.0 x16 host interface, the card supports NVIDIA Multi-Host technology so up to four independent servers can share the adapter, plus Socket Direct for splitting PCIe lanes across dual-socket platforms. The MCX75343AMS-NEAC carries hardware-enforced Secure Boot to protect firmware integrity, along with ConnectX-7's full RDMA stack featuring SHARP in-network computing and RoCE v2. Unlike the crypto-enabled MC variant, this SKU omits the inline IPsec/TLS encryption engine, offering a cost-optimized option where encryption is handled elsewhere in the stack. GPUDirect RDMA, adaptive routing and advanced congestion control keep the card ready for the largest AI training clusters.
