Huawei Technologies Assigned Five Patents

Storage method and apparatus, computing device, storage system, and storage medium
Huawei Technologies Co., Ltd., Shenzhen, China, has been assigned a patent (11809738) developed by He, Changjun, and Chen, Can, Chengdu, China, for “data storage method and apparatus, computing device, storage system, and storage medium.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”A data storage method, a computing device, and a storage system determine, from S stripes, chunks written in one batch, wherein a quantity of chunks that are in the chunks written in one batch and that belong to a same stripe is less than or equal to N, where each of the S stripes comprises (M+N) chunks, where the (M+N) chunks comprise M data chunks and N parity chunks, and where S, M, and N are positive integers, and in turn write the chunks written in one batch to M+N storage devices.”

The patent application was filed on 2022-01-20 (17/579865).

Data migration based on use algorithm
Huawei Technologies Co., Ltd., Shenzhen, China, has been assigned a patent (11809732) developed by Xie, Jin, Shenzhen, China, and Liu, Gang, Hangzhou, China, for “method and apparatus of data migration based on use algorithm.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”A memory data migration method, apparatus, and system are provided. During memory migration, data is classified into two parts based on a hot and cold degree of the data. Hot data is directly migrated, and cold data is written into a shared storage device shared by memories. When needing to be used in a destination-end memory, the cold data may be read from the shared storage device. This reduces an amount of data that needs to be migrated to the destination-end memory, thereby improving memory migration efficiency.”

The patent application was filed on 2022-08-23 (17/893499).

Storage controller and data migration monitoring
Huawei Technologies Co., Ltd., Shenzhen, China, has been assigned a patent (11809730) developed by Zhang, Xianfu, and Wang, Zhengbo, Dongguan, China, for “storage controller and data migration monitoring method.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”A storage controller is coupled to a memory, and the memory includes a first storage area and a second storage area. The storage controller includes a data migration circuit and a data operation determining circuit. The data migration circuit is configured to generate a migration signal, to migrate data in the first storage area to the second storage area. In a process in which the data migration circuit migrates all the data in the first storage area to the second storage area, the data operation determining circuit is configured to: receive and monitor a data operation signal input to the memory, and output a data migration failure signal when detecting that the data operation signal is a data modify signal with respect to the first storage area.”

The patent application was filed on 2021-07-30 (17/389461).

Distributed storage
Huawei Technologies Co., Ltd., Shenzhen, China, has been assigned a patent (11809726) developed by Zhang, Yong, Hangzhou, China, Cai, Yicong, Shenzhen, China, and Shetty S, Ajith Raj, Bangalore, India, for “distributed storage method and device.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”A distributed storage method includes offline merging, by a first thread service of a distributed storage system, M small files in a file system, generating, by the first thread service, M pieces of metadata in the offline merging process, loading, by a second thread service of the distributed storage system, the M pieces of metadata into a metadata set, searching, by the second thread service, the metadata set for metadata of a first small file when the second thread service receives a first instruction, and performing, by the second thread service, the operation corresponding to the first instruction when the second thread service finds the metadata of the first small file in the metadata set.”

The patent application was filed on 2022-03-07 (17/688030).

Redundancy in active-active cluster system
Huawei Technologies Co., Ltd., Shenzhen, China, has been assigned a patent (11809291) developed by Chen, Yijia, Chengdu, China, and Liu, Hui, Hangzhou, China, for “method and apparatus for redundancy in active-active cluster system“

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”A method is applied to a system including a host cluster and at least one pair of storage arrays. The host cluster includes a quorum host, which includes a quorum unit. The quorum host is an application host having a quorum function. A pair of storage arrays includes a first storage array and a second storage array. The quorum host receives a quorum request, temporarily stops delivering a service to the first storage array and the second storage array, determines, from the first storage array and the second storage array, which is a quorum winning storage array and which is a quorum losing storage array according to logic judgment, stops the service with the quorum losing storage array, sends quorum winning information to the quorum winning storage array, and resumes the delivered service between the host cluster and the quorum winning storage array.”

The patent application was filed on 2021-11-18 (17/529770).
