1. A storage infrastructure that generates hash values based on a coding redundancy, comprising: a storage system configured to selectively output (a) a specified data block with a corresponding coding redundancy and (b) a coding redundancy without a corresponding data block; a host having logic for issuing a normal read command to retrieve the specified data block with the corresponding coding redundancy and for issuing a redundancy read command to retrieve the coding redundancy without the corresponding data block; and a hashing system implemented on the host for hashing the coding redundancy obtained in response to the redundancy read command to generate a hash value based on the coding redundancy.
