### Open Network Operating System: SONiC and NVIDIA® Cumulus®

---

### Improved AI Cloud Performance

NVIDIA Spectrum-X Ethernet enhances [network performance by 1.6x](https://resources.nvidia.com/en-us-networking-ai/nvidia-spectrum-x), accelerating the processing, analysis, and execution of AI workloads and, in turn, the development and deployment of AI solutions.

### Accelerated Ethernet for Hyperscale

Powered by NVIDIA networking innovations, Spectrum-X Ethernet is fully standards-based Ethernet with support for open Ethernet stacks (SONiC) at cloud scale.

### Full-Stack Optimization and Simulation

Spectrum-X Ethernet is tuned and validated across the [full stack](https://docs.nvidia.com/networking/software/spectrumx-bundle/index.html) of NVIDIA hardware and software, creating an unmatched Ethernet solution for AI clouds. NVIDIA DSX Air integrates simulation of Spectrum-X Ethernet with the full-stack AI factory, including best-of-breed components from NVIDIA and ecosystem partners.

### Connect Data Centers for Gigascale AI

NVIDIA Spectrum-XGS Ethernet is built for scaling across multiple disparate data centers—located in different buildings or separated by hundreds of kilometers—allowing them to function as a single unified AI super-factory. Spectrum-XGS Ethernet uses a topology-aware congestion control algorithm, precise latency management, and end-to-end telemetry to deliver 1.9x higher NCCL performance in cross-data center environments.

### NVIDIA Silicon Photonics

Spectrum-X Ethernet Photonics reduces power consumption, increases reliability, and enhances AI productivity by situating the optics on the same package as the switch ASIC. Spectrum-X Ethernet Photonics enables 5x better network power efficiency, higher network resiliency, and 5x longer sustained AI application runtime compared with traditional pluggable transceiver-based networks.

### Spectrum-X Multiplane

Spectrum-X multiplane enables Ethernet to scale from thousands to hundreds of thousands of GPUs using a flat, two-tier topology. By splitting each GPU’s SuperNIC across two or more independent network planes, it overcomes single-plane limits, improves performance and resiliency, and scales Spectrum-X Ethernet networks up to 128K GPUs in two tiers—64x more than single-plane networks.

### Rack-Scale Spectrum-X Ethernet

Spectrum-X Ethernet is fully integrated into the NVIDIA MGX™ ETL rack-scale architecture, delivering high-performance Ethernet networking for ultra-dense compute racks and expanding MGX liquid-cooling and reliability innovations to a wider variety of compute options. The power-efficient, copper-based cable cartridge connects liquid-cooled Spectrum-X Ethernet switch trays to up to 256 GPUs in a single rack, while front-panel optical connectivity enables scale-out to larger GPU domains.
