Product Description
The NVIDIA Mellanox ConnectX-7 MCX755106AC-HEAT is a dual-port 200Gb/s VPI (Virtual Protocol Interconnect) smart adapter from NVIDIA's seventh-generation ConnectX family, capable of running native InfiniBand NDR200/HDR or 200GbE Ethernet on each QSFP112 port. Installed through a PCIe 5.0 x16 host interface, the card is Socket Direct ready, allowing an optional auxiliary card to split its PCIe lanes across two CPU sockets on supported dual-socket platforms for reduced cross-socket latency. The MCX755106AC-HEAT carries ConnectX-7's full RDMA stack - native InfiniBand transport with SHARP in-network computing acceleration, plus RoCE v2 for RDMA over Ethernet fabrics - together with hardware-enforced Secure Boot and an onboard cryptographic engine for inline IPsec/TLS encryption offload. GPUDirect RDMA, adaptive routing and advanced congestion control round out a feature set built for latency-sensitive AI/ML training, HPC and high-performance storage networking, while the standard PCIe stand-up form factor keeps the card compatible with a broad range of server chassis.
