Ethernet Fundamentals

High-Performance Networks with Acceleration

One-third of the 30 million data center servers shipped every year are consumed by the software-defined data center stack. To support heavy data center workloads, enterprises need to modernize their network infrastructure and evolve to keep up with the exponential demand for data processing.

Techniques for network acceleration continue to evolve and are becoming more specialized. The latest developments address AI workloads, which demand consistent, predictable performance along with compute and power efficiencies suitable for running multi-tenant environments.

Powering AI Dreams: NVIDIA's InfiniBand and Ethernet Switches

The world’s first networking platforms capable of end-to-end 800Gb/s throughput, NVIDIA Quantum-X800 InfiniBand and NVIDIA Spectrum™-X800 Ethernet push the boundaries of networking performance for computing and AI workloads. They feature software that further accelerates AI, cloud, data processing and HPC applications in every type of data center, including those that incorporate the newly released NVIDIA Blackwell architecture-based product lineup.

NVIDIA Ethernet Switches

“NVIDIA Networking is central to the scalability of our AI supercomputing infrastructure,” said Gilad Shainer, senior vice president of Networking at NVIDIA.

“NVIDIA X800 switches are end-to-end networking platforms that enable us to achieve trillion-parameter-scale generative AI essential for new AI infrastructures.”

Initial adopters of Quantum InfiniBand and Spectrum-X Ethernet include Microsoft Azure and Oracle Cloud Infrastructure.

NVIDIA ConnectX NICs

Furthermore, NVIDIA's networking solutions include SmartNICs (Network Interface Cards) and accelerated networking technologies, enhancing data center efficiency and reducing CPU overhead. These SmartNICs offload networking tasks, such as packet processing and security functions, freeing up CPU resources for compute-intensive tasks.

NVIDIA Self-Healing Network Technology Enables Unbreakable Data Centers

In today’s networks, a traditional subnet manager will recognize failed links and recalculate routes to avoid the problem, but this can take up to 5 seconds for 1,000 nodes and 30 seconds for clusters with 10,000 or more nodes—not fast enough to keep an application running seamlessly. The self-healing network capabilities of NVIDIA Quantum InfiniBand switches overcome link failures, enabling network recovery much faster than any other software-based solution.
