Fujitsu Ltd., Kawasaki, Japan, has been assigned a patent (11665228) developed by Shiraki, Osamu, Kawasaki, Japan, for “management device, storage system, and information processing method.”

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A management device of a storage system, the management devices includes a memory and a processor. The processor coupled to the memory and configured to acquire workload load information and system load information when executing a container, and determine a workload arrangement destination and a replica position of a volume based on the workload load information and the system load information when activating a workload.”

The patent application was filed on 2022-03-03 (17/686022).

Storage device and control method
Fujitsu Ltd., Kawasaki, Japan, has been assigned a patent (11637566) developed by Miki, Atsushi, Yokohama, Japan, for “storage device and control method for storage device.”

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A storage device includes: a memory, and a processor configured to, at the time of writing data into the memory, generate a first check code common to a plurality of types of error correction codes from the data on the basis of a correlation relationship between the plurality of types of error correction codes, add the first check code to the data and write the data into the memory, convert the first check code into a second check code based on any one of the plurality of types of error correction codes at the time of reading the data from the memory, and perform error correction by using the second check code.”

The patent application was filed on 2022-01-18 (17/577422).

Storage device and control method
Fujitsu Ltd., Kawasaki, Japan, has been assigned a patent (11573729) developed by Maeda, Jun, Kawasaki, Japan, for “storage device and control method for storage device.”

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A storage device communicably coupled to a host device and another storage device includes a memory and a processor coupled to the memory and configured to: write, in a case where an area release command of a transaction volume is issued from the host device while data backup processing is performed with the another storage device using a generation-managed transmission buffer, the area release command in a first generation of the transmission buffer, and switch, in a case where a range of data write processing requested by the host device overlaps a range specified by the area release command written in the first generation, a generation of the transmission buffer from the first generation to a second generation.”

The patent application was filed on 2021-07-09 (17/371164).

Backup management device, method, and information processing
Fujitsu Ltd., Kawasaki, Japan, has been assigned a patent (11550671) developed by Nakamura, Takuji, Matsuda, Junichi, Kawasaki, Japan, Miyauchi, Keiji, Yokohama, Japan, and Doshita, Akihiro, Kawasaki, Japan, for “backup management device, backup management method, and information processing system.”

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A backup management device includes a database and a processor. The database is configured to store configuration information of physical resource including a physical storage device, configuration information of virtual resource including a virtual storage device, and relationship information of the virtual resource and the physical resource. The processor is configured to generate, when the virtual storage device is provided to a user, backup information related to backup control of the physical storage device associated with the virtual storage device based on information stored in the database. The processor is configured to perform backup of the virtual storage device by copying a physical storage device associated with the virtual storage device to another physical storage device based on the generated backup information.”

The patent application was filed on 2021-08-11 (17/399097).
