Summary:A method of writing data to a distributed file system including a file system client, a server and a storage resource target, includes generating, on the client, a write request including a byte stream to be written to the storage resource target; formatting, on the client, the byte stream into sectors in accordance with the T10 protocol, the sectors including a data field and a protection information field, the protection information field including a guard field, an application field and a reference field; computing, on the client, checksum data for the guard field; sending, across a network, the data and the protection information to the server; verifying, in T10-capable hardware on the server, the checksum data for the guard field; verifying, on the storage resource target, the checksum data for the guard field; and storing the data on the storage resource target.
