Hot Chips\u2014NVIDIA today announced NVIDIA\u00ae Spectrum-XGS Ethernet, a scale-across technology for combining distributed data centers into unified, giga-scale AI super-factories.<\/p>\n
As AI demand surges, individual data centers are reaching the limits of power and capacity within a single facility. To expand, data centers must scale beyond any one building, which is limited by off-the-shelf Ethernet networking infrastructure with high latency and jitter and unpredictable performance.<\/p>\n
Spectrum-XGS Ethernet is a breakthrough addition to the NVIDIA Spectrum-X<\/a>\u2122 Ethernet platform that removes these boundaries by introducing scale-across infrastructure. It serves as a third pillar of AI computing beyond scale-up and scale-out, designed for extending the extreme performance and scale of Spectrum-X Ethernet to interconnect multiple, distributed data centers to form massive AI super-factories capable of giga-scale intelligence.<\/p>\n \u201cThe AI industrial revolution is here, and giant-scale AI factories are the essential infrastructure,\u201d said Jensen Huang, founder and CEO of NVIDIA. \u201cWith NVIDIA Spectrum-XGS Ethernet, we add scale-across to scale-up and scale-out capabilities to link data centers across cities, nations and continents into vast, giga-scale AI super-factories.\u201d<\/p>\n Spectrum-XGS Ethernet is fully integrated into the Spectrum-X platform, featuring algorithms that dynamically adapt the network to the distance between data center facilities.<\/p>\n With advanced, auto-adjusted distance congestion control, precision latency management and end-to-end telemetry, Spectrum-XGS Ethernet nearly doubles the performance of the NVIDIA Collective Communications Library<\/a>, accelerating multi-GPU and multi-node communication to deliver predictable performance across geographically distributed AI clusters. As a result, multiple data centers can operate as a single AI super-factory, fully optimized for long-distance connectivity.<\/p>\n Hyperscale pioneers embracing the new infrastructure include CoreWeave, which will be among the first to connect its data centers with Spectrum-XGS Ethernet.<\/p>\n \u201cCoreWeave\u2019s mission is to deliver the most powerful AI infrastructure to innovators everywhere,\u201d said Peter Salanki, cofounder and chief technology officer of CoreWeave. \u201cWith NVIDIA Spectrum-XGS, we can connect our data centers into a single, unified supercomputer, giving our customers access to giga-scale AI that will accelerate breakthroughs across every industry.\u201d<\/p>\n The Spectrum-X Ethernet networking platform provides 1.6x greater bandwidth density than off-the-shelf Ethernet for multi-tenant, hyperscale AI factories \u2014 including the world\u2019s largest AI supercomputer<\/a>. It comprises NVIDIA Spectrum-X switches and NVIDIA ConnectX\u00ae-8 SuperNICs<\/a>, delivering seamless scalability, ultralow latency and breakthrough performance for enterprises building the future of AI.<\/p>\n Today\u2019s announcement follows a drumbeat of networking innovation announcements from NVIDIA, including NVIDIA Spectrum-X and NVIDIA Quantum-X silicon photonics networking switches<\/a>, which enable AI factories to connect millions of GPUs across sites while reducing energy consumption and operational costs.<\/p>\n Availability
