CASE STUDY Defence and Space Launches a Petascale Archive for Data with StorNext Scale-out Storage Based in the , Airbus Defence and Space archives critical data streaming from observation managed by the (ESA). The Airbus team selected Quantum StorNext scale-out storage to enable scale and to provide access to this fast-growing data collection.
