Product Description
The NVIDIA Mellanox ConnectX-7 MCX753436MS-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 (the card ships in Ethernet default mode), 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. The MCX753436MS-HEAB 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, making it a cost-optimized choice where encryption is handled elsewhere in the stack. The tool-less OCP 3.0 form factor enables hot-swappable serviceability in dense hyperscale chassis.
