Method and system for offloading a continuous health-check and reconstruction of data using compute acceleration devices on persistent storage devices

摘要

A method for managing data includes identifying, by a compute acceleration device (CAD) of a persistent storage device, a first chunk, stored in the persistent storage device, to be health-checked using storage metadata, generating a first chunk identifier using the first chunk, making a determination that the first chunk identifier does not match a second chunk identifier stored in the storage metadata, and in response to the determination: obtaining a plurality of chunks associated with the first chunk from a plurality of persistent storage devices of a storage system, wherein the storage system comprises the persistent storage device and the plurality of persistent storage devices, regenerating the first chunk using the plurality of chunks to generate a new first chunk, storing the new first chunk in the persistent storage device, and updating the storage metadata based on storage of the new first chunk.
