Optimized end-to-end integrity storage system

Abstract:

A method of optimized end-to-end integrity comprises receiving a request to write application data stored in a first kernel buffer to a storage device. The method further comprises determining, by a processing device, that a first cyclic redundancy check (CRC) of the application data failed. The method further comprises copying the application data to a second kernel buffer. The method further comprises performing, by the processing device, a second CRC on the application data stored in the second kernel buffer.
