What Mellanox Technologies does

Mellanox Technologies, founded in 1999 in Israel, designs and sells high-performance networking interconnect silicon, switches, adapter cards, DPUs, and management software for AI and HPC data centers. Its core technology stack spans InfiniBand (Quantum-X800, Quantum-2) and Ethernet (Spectrum-X) switching platforms, ConnectX adapter cards, BlueField data processing units, co-packaged silicon photonics, and a software layer including DOCA, UFM, NetQ, Cumulus Linux, and Pure SONiC. Together these form an integrated full-stack AI fabric — NVLink handles GPU scale-up within a server, InfiniBand and Spectrum-X handle scale-out across racks and data centers, BlueField DPUs offload infrastructure processing, and the software stack manages fabric telemetry, automation, and security. Co-packaged silicon photonics provide 3.5x power efficiency and 63x signal integrity improvements, enabling the company to target AI factories scaling to millions of GPUs.

The company operates as a wholly-owned subsidiary of Nvidia following the April 2020 close of a $6.9 billion acquisition (announced in 2019). Pre-acquisition, Mellanox was a NASDAQ-listed company; post-acquisition, it is fully integrated into Nvidia's networking business unit and its products are sold through Nvidia's enterprise sales force, GTC conference, and certified partner network, targeting hyperscale cloud providers (Microsoft Azure, Meta, Oracle, xAI) and large enterprise AI infrastructure operators. Pricing is not publicly disclosed; the business model is configuration-based, large-contract enterprise sales of networking hardware bundled with Nvidia GPU and software stacks.

As of Q1 2026, the Nvidia networking segment that Mellanox anchors generated approximately $11 billion in quarterly revenue (263% year-over-year growth), with data center switching alone growing 192.7% YoY to $2.1 billion. Nvidia captured 21.5% market share of the $10 billion data center Ethernet switch market in Q1 2026, up from 4% in Q1 2024. The acquisition has been validated as strategically transformative, turning Mellanox's networking IP into Nvidia's second-largest revenue sector and the binding constraint for frontier AI infrastructure.
