Publication number: 20240126641Abstract: A client device may transmit a data stream including an object (such as a data file or record) to a storage system for storing the object in a storage device. In response to receiving the data stream, the storage system may store or write data of the object into a plurality of logical blocks of the storage device with an end-to-end data protection based at least in part on a comparison of a combination of check codes of a header of the object, the object and padding data with a combination of a plurality of check codes that are generated separately for metadata associated with the object and corresponding parts of the object stored in the plurality of logical blocks. The storage system may further provide an end-to-end data protection for reading data of an object stored in multiple logical blocks of a storage device.Type: ApplicationFiled: January 22, 2021Publication date: April 18, 2024Inventors: Yikang Xu, Peng Xu, Rui Wang, Yu Du
