48 SSDs With Full Visibility: Building an NVIDIA SCADA-Style Data Platform With Scorpio™ P-Series 320L Switch

Nearly every assumption in conventional storage topology design comes from an era when the CPU issued the reads. NVIDIA’s SCADA architecture removes the CPU from the storage metadata queue management, allowing thousands of GPU threads to issue fine-grained I/O requests directly to storage at massive parallel scale.That raises a more practical question for AI infrastructure: If thousands… Read more

Accelerating AI Design and Deployment: Modularity Is How Inference Capacity Gets Built

Inference demand is growing faster than the industry can build for it. Modularity at every level, from chip to grid, is how capacity gets built fast enough.This theme ran through the 2026 OCP Global Summit. AMD CEO Dr. Lisa Su called 2026 “the year of inference,” with agentic traffic up 14x this year. Dr. Dimitrios Ziakas, CTO of Hyve Solutions, pointed to a 7x year-over-year jump in… Read more
