Abstract
A data retention event preparation/recovery system includes a chassis, a plurality of NAND subsystems included in the chassis, and a data retention event preparation/recovery subsystem that is included in the chassis and coupled to the plurality of NAND subsystems. The data retention event preparation/recovery subsystem determines that the plurality of NAND subsystems will experience a data retention event and, in response, identifies a first subset of the plurality of NAND subsystems that exceed an error threshold, identifies at least one overprovisioned block in the plurality of NAND subsystem, copies data that is stored on the first subset of the plurality of NAND subsystems to the at least one overprovisioned block in the plurality of NAND subsystems, and power offs the plurality of NAND subsystems to begin the data retention event.
