MT28908A0-NCCF-HVM, Mellanox ConnectX-6 Network Adapter, 2xHDR/200GbE, Multi-Host, PCIe 4.0 x32

The Mellanox NVIDIA Mellanox MT28908A0-NCCF-HVM is a high-performance ConnectX-6 VPI network controller IC designed for demanding data center and cloud infrastructure. As a core PCIe device IC, it is built for integration into adapters, custom server boards, and storage networking designs that need consistent low latency and very high throughput. With two high-speed ports supporting HDR InfiniBand or 200 GbE per port, the NVIDIA Mellanox MT28908A0-NCCF-HVM helps system builders deliver scalable, fabric-ready connectivity for modern clusters in Asia, Europe, Africa, and North America.

This ConnectX-6 VPI controller IC supports both InfiniBand and Ethernet operation through Virtual Protocol Interconnect (VPI), giving integrators flexibility to deploy a single hardware design across different network architectures. The dual-port design allows efficient use of PCI Express 4.0 / 3.0 x32 bandwidth and supports multi-host topologies, which is ideal for dense servers and shared storage platforms used by distributors, small and mid-size integrators, and advanced end users. The NVIDIA Mellanox MT28908A0-NCCF-HVM is a “No Crypto” variant with no onboard cryptographic engine, which can simplify export, compliance, and qualification processes in various regions.

Typical use cases include high-performance adapters and embedded designs where HDR InfiniBand or 200 GbE connectivity is required, such as large-scale compute clusters, storage fabrics, and low-latency trading or research environments. Integrators can design cards or on-board solutions around this controller IC to match local market needs while keeping a consistent technology base across multiple geographies. The NVIDIA Mellanox MT28908A0-NCCF-HVM fits well into enterprise data centers and HPC deployments that must balance high bandwidth, flexibility between InfiniBand and Ethernet, and efficient PCIe utilization.
