The FlashArray//XL features a 5 Rack Unit (5U) chassis height.
This form factor represents a significant change from the standard FlashArray//X and //C series, which utilize a 3U chassis. The increase to 5U is engineered to support the massive performance and density requirements of the //XL platform.
Key Design Features: The 5U height accommodates:
Dual Controllers: Larger, high-performance controllers with increased airflow requirements.
40 DirectFlash Module Slots: Double the drive density of the 3U chassis (which holds 20), allowing for petabytes of effective capacity in the base unit.
4 Power Supplies: A 2+2 redundant power architecture.
9 PCIe Slots: Extensive I/O expansion for host and backend connectivity.
Airflow: Dedicated fan modules and thermal ducting to cool the high-wattage components (up to 3.5kW max power draw).
