Patent number: 11467905Abstract: A stripe merging method and system based on erasure codes are provided. A StripeMerge-P algorithm is used first to determine alignment information of parity chunks of erasure code stripes based on a preprocessed hash table. Through a greedy strategy, erasure code stripe pairs to be merged are selected for merging. Through the hash table, location information of the parity chunks is directly looked up, so that no additional computing overhead is required, and the overhead of selecting and merging the erasure code stripe pairs is further reduced through the combination with the greedy strategy.Type: GrantFiled: September 16, 2021Date of Patent: October 11, 2022Assignee: HUAZHONG UNIVERSITY OF SCIENCE AND TECHNOLOGYInventors: Yuchong Hu, Qiaori Yao, Liangfeng Cheng, Yazhe Zhang, Dan Feng

Patent number: 10083117Abstract: Technologies are generally described herein to detect non-volatile write request sequences. A write request is received to write to a solid-state device that includes the non-volatile memory. A determination is made as to whether the write request is part of a non-volatile write request sequence or is not part of the non-volatile write request sequence. In response to determining that the write request is part of the non-volatile write request sequence, the write request is associated with the non-volatile write request sequence. In response to determining that the write request is not part of the non-volatile write request sequence, the data associated with the write request is written to a cache that is coupled to the non-volatile memory. The data associated with the non-volatile write request sequences may be written directly to the non-volatile memory.Type: GrantFiled: September 9, 2014Date of Patent: September 25, 2018Assignee: Hua Zhong University of TechnologyInventors: Dan Feng, Wen Zhou, Jingning Liu, Wei Tong, Yu Hua, Shuangwu Zhang
