Huawei Technologies and University of Science and Technology of China Assigned Patent

Huawei Technologies Co., Ltd., Shenzhen, China, and University of Science and Technology of China, Hefei, China, has been assigned a patent (10,908,833) developed by Xu, Yinlong, Li, Zhipeng, Hefei, China, and Wang, Yuangang, Shenzhen, China, for a “data migration method for a storage system after expansion and storage system.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”A data migration method for a storage system after expansion and a storage system are provided. After an i.sup.th expansion is performed on the storage system, data migration is performed by using an auxiliary balanced incomplete block design. Because a quantity of tuples including any element in the auxiliary balanced incomplete block design is identical, and each migration unit includes an identical quantity of parity chunks, a data migration amount after the expansion is minimized. In this way, time required for data migration after the expansion is significantly reduced, and a delay in a response to a user request that is caused because a data migration operation needs to be performed after the expansion is also reduced.”

The patent application was filed on March 4, 2019 (Appl. No.16/291,852).
