End-to-end checksumming for read operations |
摘要 |
Described are techniques used in detection of a data corruption in a computer system in connection with read and write operations. For a write operation, a host issues a write request that includes a checksum value determined in accordance with data associated with the write request. The write request is received by a data storage system that performs data validation using the checksum. The host issues a vendor-defined write request operation that includes the checksum as a data field in the request packet sent to the data storage system. For a read operation, a host issues a read request and the data storage system determines a checksum value before servicing the read request. The checksum is validated at the top of the I/O stack on the host by the file system filter driver.
