Abstract: Systems and methods for offloading data processing tasks using in-storage code execution are disclosed. For example, a data storage system including one or more processors, a non-transitory storage medium, and a storage logic executable by the one or more processors to perform operations including: receiving portable code configured to perform a data processing offload task, the portable code comprising one or more translatable, hardware-agnostic instructions for processing data stored on the storage medium; translating and executing the one or more translatable, hardware-agnostic instructions of the portable code to perform the data processing offload task using a translation and execution engine disposed in the storage logic; determining that use of the portable code has concluded; and responsive to determining that use of the portable code has concluded, releasing the portable code.

Abstract: Methods and systems for rebuilding a failed storage device in a data storage system. For example, a method including identifying a first garbage collection group (GCG) in a storage array for garbage collection; extracting valid data and redundancy information from functioning storage devices in the storage array associated with the first GCG; reconstructing data of a failed storage device associated with the first GCG based on the extracted valid data and redundancy information from the functioning storage devices associated with the first GCG; consolidating the extracted valid data from the functioning storage devices and the reconstructed data of the failed storage device associated with the first GCG; writing the consolidated extracted valid data from the functioning storage devices and the reconstructed data of the failed storage device associated with the first GCG to a second GCG in the storage array; and reclaiming the first GCG identified for garbage collection.

Abstract: Methods and systems for rebuilding a failed storage device in a storage system using a plurality of dynamically selected locations in a system-level overprovisioned (OP) space. For example, a method including designating a portion of a usable space in a storage system as a system-level OP space; in response to a detection of a failed storage device in the storage system, reconstructing data of the failed storage device based on data read from a plurality of functioning storage devices in the storage system; and storing the reconstructed data of the failed storage device in a plurality of dynamically selected locations in the system-level OP space of the plurality of functioning storage devices.
