The Network Defines the AI Data Center

Next-generation networking for high-performance, scalable, and secure gigascale AI factories.

Introduction

Networking Purpose-Built for the Era of AI Factories

AI factories now span tens of thousands of GPUs—and soon, millions—operating as a single distributed computing engine. To keep accelerators fully utilized, AI workloads demand deterministic latency, lossless throughput, stable iteration times, and the ability to scale not only within a data center, but across multiple sites.

NVIDIA networking delivers the full-stack fabric that makes this possible, combining NVIDIA NVLink™ scale-up, NVIDIA Quantum InfiniBand and Spectrum-X™ Ethernet scale-out, Spectrum-XGS multi-data-center scale-across, NVIDIA® BlueField® DPU and DOCA™ for infrastructure services, and next-generation silicon-photonics platforms to power the world’s most advanced AI factories.
