Often overlooked by the general public, the data center network serves as the backbone for all communications between nodes. NVIDIA anticipates the emergence of data centers housing millions of GPUs, requiring efficient interconnection across facilities to support the most advanced AI models. To address this need, NVIDIA introduces Spectrum-XGS Ethernet, an advanced extension of the Spectrum-X networking platform, specifically engineered to integrate distributed data centers into a cohesive AI supercomputing ecosystem.
