Abstract
A method of managing read/write requests in a non-transitory data storage system includes receiving a read/write request for data stored in the data storage system and processing the read/write request on at least one computing processor. For a read request, the method includes computing a first checksum of the data, comparing the first checksum with a second checksum associated with the data, and allowing a read operation of the read/write request on the data when the first and second checksums match. For a write request, the method includes allowing a write operation of the read/write request on the data, computing a third checksum of the modified data, and associating the third checksum with the modified data.
