Episode 701: Everpure’s Rob Lee on GPUs, Data Gravity, and KV Cache
Rob Lee, Chief Technology and Growth Officer at Everpure (formerly Pure Storage), is back on the show. Keith Townsend asks how a CTO tells a real compute shortage from a data problem dressed up as one. Rob's answer: stop chasing GPU utilization. Measure how long a task takes and how accurate the result is, and utilization follows. From there, data gravity and why agents working inside transactional flows pull compute toward the data, why AI pushes enterprises to reason across every silo at once instead of one application stack like SAP, and KV cache offload as the first layer of a new memory hierarchy for inference. Rob closes with what Everpure has shipped and what's still on the roadmap.
