NVIDIA Spectrum-X Network Platform Architecture

Presented by Gilad Shainer (Nvidia) | David Iles (Nvidia)
The NVIDIA Spectrum-X Networking Platform is the first Ethernet platform designed specifically to improve the performance of Ethernet-based AI clouds. This technology achieves 1.7X improved AI performance for massive AI workloads such as LLM, along with 1.7X better power efficiency and predictable performance in multi-tenant environments. Spectrum-X is built on the tight coupling of the Spectrum-4 Ethernet switch with the NVIDIA BlueField-3 data processing unit (DPU).
Spectrum-X platform is based on the combination of lossless Ethernet connectivity with fine grain adaptive routing and direct data placement for achieving nearly perfect effective bandwidth at load and scale. Telemetry based congestion control and special network delivery data path create the conditions of performance isolations for multi-tenant AI at scale. The session will provide a technical review of the AI Ethernet network innovations presented with Spectrum-X platform.
