摘要
An apparatus, according to one embodiment, includes non-volatile memory configured to store data, and a controller and logic integrated with and/or executable by the controller, the logic being configured to: determine, by the controller, that at least one block of the non-volatile memory and/or portion of a block of the non-volatile memory meets a retirement condition, re-evaluate, by the controller, the at least one block and/or the portion of a block to determine whether to retire the at least one block and/or the portion of a block, indicate, by the controller, that the at least one block and/or the portion of a block remains usable when a result of the re-evaluation is not to retire the block, and indicate, by the controller, that the at least one block and/or the portion of a block is retired when the result of the re-evaluation is to retire the block.

According to some embodiments, the storage system (such as 800) may include logic configured to receive a request to open a data set, logic configured to determine if the requested data set is stored to a lower storage tier 806 of a tiered data storage system 800 in multiple associated portions, logic configured to move each associated portion of the requested data set to a higher storage tier 802 of the tiered data storage system 800, and logic configured to assemble the requested data set on the higher storage tier 802 of the tiered data storage system 800 from the associated portions.
Of course, this logic may be implemented as a method on any device and/or system or as a computer program product, according to various embodiments.
