  • Why the network isn't the bottleneck — storage I/O, host architecture, and software are.
  • The co-design principle and the "Drainage Basin Pattern."
  • Burst buffers (NVMe staging) as the key architectural component.
  • Real results: 1 PB in 29 hours at 96% link utilization, and the KEK Cryo-EM cloud case.
