Traditional cloud infrastructure was designed for predictable, general-purpose workloads and standard interfaces. Agentic AI factories connect diverse users, agents, applications, data sources, and storage systems to massively accelerated compute at multi-terabit bandwidth per server, making dedicated DPU processing essential for line-rate networking, storage, and security. NVIDIA is introducing Scale-In network infrastructure, the fifth pillar of NVIDIA AI networking, bringing purpose-built acc
