| Conditions | Nodes = blades: minimum 7, up to 10 blades per 5U chassis, up to 4 DirectFlash Modules per blade (base_drive_bays = 10 x 4 per chassis). The FlashBlade product page quotes up to 650GB/s for FlashBlade//S and sustained up to 55GB/s per chassis, not per model, so throughput is null. raw_tb_max, nodes_max and drives_max are derived (1,200TB per blade, 4 DFMs per blade, 10 blades x 10 chassis); Pure does not state a system total. Uplinks: up to 16x 400GbE (multi-chassis). power_w = 2,750 W nominal per fully populated chassis. R2 blades released 2025 per Pure's Sept 2025 launch blog.
