tech π‘ Nvidia's new 'fifth' AI networking pillar is shaky
Nvidia introduced a concept called 'scale-in' as its fifth pillar for AI networking during the Hot Chips event in Palo Alto, California. This feature uses hardware like the BlueField-4 DPU to speed up data flow between internal and external systems. The company claims this offloads security and storage tasks from main processors, supporting agentic workload demands. While scale-in seems industry-aligned, its foundation is considered uncertain compared to established pillars. Additionally, Nvidia showcased Spectrum-X in an eight-plane topology, maintaining 90% bandwidth if one plane fails.
