Inspur Suzhou Intelligent Technology Assigned Two Patents

Online migration of multi-disk virtual machine into different storage pools
Inspur Suzhou Intelligent Technology co., Ltd., Jiangsu, China, has been assigned a patent (11740925) developed by Meng, Linglu, and Zhang, Dong, Jiangsu, China, for “method and apparatus for online migration of multi-disk virtual machine into different storage pools.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A method and apparatus for online migration of a multi-disk virtual machine into different storage pools are provided. The method includes: constructing disk trees by using each active disk to be migrated of a virtual machine and a plurality of snapshot disks that are correspondingly generated based on each active disk to be migrated, so as to record a generation time sequence of a plurality of disks in the disk tree, migrating a memory snapshot file, and determining a target storage pool corresponding to each active disk to be migrated, and migrating a plurality of disk trees into corresponding target storage pools respectively according to the generation time sequence of the disk to be migrated in the disk tree.”

The patent application was filed on 2021-02-19 (18/016998).

Solid state disk access method and apparatus, device, and medium
Inspur Suzhou Intelligent Technology co., Ltd., Jiangsu, China, has been assigned a patent (11734113) developed by Shao, Wenhao, Jiangsu, China, for “method and apparatus for online migration of multi-disk virtual machine into different storage pools.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A solid state disk access method includes: determining, in response to a read error, a first read voltage of the current data block according to a current data storage time interval to which a data storage time of the current data block belongs, performing reread error correction on the data in the current data block based on the first read voltage, determining, if reread error correction of the current data block fails, a second read voltage corresponding to the current data block according to the current data storage time interval and a preset data read rule that is determined based on the data storage time interval and the number of data reads, and performing reread error correction on the data in the current data block based on the second read voltage until the reread error correction of the current data block meets a preset reread error correction condition.”

The patent application was filed on 2021-02-20 (18/009820).
