Huawei Cloud Computing Technologies Assigned Five Patents

Data backup
Huawei Cloud Computing Technologies Co., Ltd., Gui’an New District, China, has been assigned a patent (11907561) developed by He, Xionghui, Shenzhen, Ding, Chen, Hangzhou, and Yao, Di, Shenzhen, China, for “data backup method and apparatus.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “This application provides a data backup method. The method includes: obtaining, by a first node, an identifier of a backup execution node from a storage device, and backing up data of the first node in the storage device responsive to determining that an ID of the first node is the same as the ID of the backup execution node. The embodiments of this application can improve reliability of the data stored by the first node, and prevent a plurality of nodes from redundantly backing up duplicate data in the storage device. The techniques disclosed herein reduce resource consumption.”

The patent application was filed on 2020-07-14 (16/928677).

Stripe reassembling method in storage system and stripe server
Huawei Cloud Computing Technologies Co., Ltd., Gui’an New District, China, has been assigned a patent (11899533) developed by Zhan, Yun, Xie, Huiyun, Wang, Tonglei, Shenzhen, China, for a “stripe reassembling method in storage system and stripe server.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A stripe reassembling technique includes a stripe server that selects stripes, uses data chunks including valid data in the stripes S.sub.1, S.sub.2, and S.sub.3 as data chunks in a new stripe S.sub.4, and generates data of a parity chunk for data of the data chunks in S.sub.4 according to an erasure coding (EC) algorithm the same as that of S.sub.1, S.sub.2, and S.sub.3 , and stores the parity data of the parity chunk on a parity storage node.”

The patent application was filed on 2021-06-24 (17/356849).

Storage and data retrieval methods and devices
Huawei Cloud Computing Technologies Co., Ltd., Gui’an New District, China, has been assigned a patent (11853298) developed by Pesala, Ravindra, Karnataka, India, Subramanya, Raghunandan, Bangalore, India, and Gollamudi, Venkata Ramana, Karnataka, India, for “data storage and data retrieval methods and devices.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A method includes receiving data in a first format to be written into a data storage, where the first format is a multiversion concurrency control (MVCC) row format. The data is stored in the first format in the data storage and is transitioned from the first format to a second format based on a first transition parameter, where the second format is an MVCC columnar format. Data is stored in the second format in the data storage and is transitioned from the second format to a third format based on a second transition parameter, where the third format is a columnar format. The data storage stores non-overlapping data in the first format, the second format, and the third format.”

The patent application was filed on 2022-04-05 (17/713366).

Storage method and apparatus in distributed storage system, and computer program product
Huawei Cloud Computing Technologies Co., Ltd., Gui’an New District, China, has been assigned a patent (11775194) developed by Wei, Mingchang, Wang, Daohui, Song, Chi, and Rao, Rong, Shenzhen, China, for “data storage method and apparatus in distributed storage system, and computer program product.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A data storage method implemented by a storage node in a distributed storage system includes receiving first data of a first strip in a first stripe, wherein the first stripe comprises a first plurality of strips, receiving second data of a second strip in a second stripe, wherein the second strip comprises a second plurality of strips, wherein a first logical address of the first data is the same as a second logical address of the second data, and generating a record indicating that the first data reaches the storage node before the second data.”

The patent application was filed on 2021-06-25 (17/358682).

Method, apparatus, and management node for managing data in partition table, and storage medium
Huawei Cloud Computing Technologies Co., Ltd., Gui’an New District, China, has been assigned a patent (11768856) developed by Feng, Wei, Beijing, China, Hong, Fucheng, Shenzhen, China, and Sui, Qi, Beijing, China, for “method, apparatus, and management node for managing data in partition table, and storage medium.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “In a method for managing data in a partition table, a server, and a storage medium, a management node obtains a creation duration range of data of a target partition in the partition table, further obtains a geographical area to which the target partition belongs, historical access information of the target partition, or a service type of the target partition, and then, when the creation duration range of the data of the target partition meets a predetermined time range of a first storage stage and a preset condition is met, the management node alters the data that is of the target partition and that has been stored based on a storage policy corresponding to a second storage stage to be stored based on a storage policy corresponding to the first storage stage.”

The patent application was filed on 2022-01-31 (17/589318).
