Product Description
The NVIDIA Mellanox ConnectX-7 MCX753436MC-HEAB is a dual-port 200Gb/s VPI smart adapter built in the OCP 3.0 Small Form Factor for hyperscale and cloud server designs. Each QSFP112 port runs native InfiniBand NDR200/HDR or 200GbE Ethernet, giving system integrators a single SKU that adapts to either fabric. Through a PCIe 5.0 x16 host interface, the card supports NVIDIA Multi-Host technology, letting up to four independent host servers share the adapter's network ports and physical connection, plus Socket Direct for splitting PCIe lanes across dual-socket platforms - both hallmarks of dense, OCP-based server deployments. The MCX753436MC-HEAB carries hardware-enforced Secure Boot and an onboard cryptographic engine for inline IPsec/TLS offload, alongside ConnectX-7's full RDMA stack with SHARP in-network computing and RoCE v2. The tool-less OCP 3.0 form factor enables hot-swappable serviceability in modern hyperscale chassis without opening the server, while GPUDirect RDMA and adaptive routing keep the card ready for demanding AI/ML and HPC fabrics.
