US Patent 11182249 Block ID encoding in an erasure coded storage system

A data storage system includes a plurality of data blocks. A set of data blocks are protected by an erasure correcting code and each of the data blocks in the set of data blocks includes block identification information. The data storage system includes a processor and logic integrated with the processor, executable by the processor, or integrated with and executable by the processor. The logic is configured to verify the block identification information for each of the data blocks in the set of data blocks at the time of read and, as part of reconstructing a data block, reconstruct the block identification information for the reconstructed data block, and verify the block identification information.
