Addressing Connectivity Bottlenecks at Rack-Scale

As AI clusters scale from single nodes to thousand-GPU fabrics, connectivity is becoming the bottleneck that prevents all that compute from reaching its potential. NVIDIA’s Blackwell and Vera Rubin architectures have fundamentally redefined what a rack can do—but that density creates new challenges at every layer: scale-up, scale-out, memory, and storage. When any one of them lags, you’re… Read more

Why Connectivity is the New Frontier of AI Infrastructure—and What NVLink Fusion Means for the Future

Every year at GTC, the conversations on the show floor and in the hallways tell you something that raw specs alone can’t. This year, what I’m hearing is a clear inflection: the era of one-size-fits-all compute is over. Hyperscalers are deploying heterogeneous racks where NVIDIA GPUs sit alongside custom accelerators, XPUs, and purpose-built silicon developed for specific workload profiles—and… Read more

Inference Tokenomics: How CXL Memory Expansion Improves AI Economics

In our last post on Breaking Through the Memory Wall, we explored how CXL memory expansion addresses fundamental constraints in RAG and KV cache management. We expand on how inference application deployment has transitioned to a distributed architecture to address the requirements of large-scale applications, and how CXL-attached memory helps improve capacity and performance while lowering… Read more
