Abstract:
A storage unit adapted for use in a processing system includes a controller including at least two compute nodes, each of the compute nodes including a read/write cache and a persistent cache; and machine executable instructions stored within machine readable media, the instructions including instructions for tracking in-flight data in the persistent cache and composing a list of the in-flight data segments after a failure of the controller. A processing system and a method are also provided.
