Abstract
A method for managing data includes obtaining, by a storage controller, data from a host, applying an erasure coding procedure to the data to obtain a plurality of data chunks and at least one parity chunk, deduplicating the plurality of data chunks to obtain a plurality of deduplicated data chunks, generating storage metadata associated with the plurality of data chunks and the at least one parity chunk, storing, across a plurality of persistent storage devices, the plurality of deduplicated data chunks and the at least one parity chunk, wherein the plurality of persistent storage devices is operatively connected to the storage controller and a second storage controller, storing the storage metadata in the storage controller, and sending a copy of the storage metadata to the second storage controller.
