Publication number: 20240427624Abstract: The present invention achieves high throughput by making efficient use of virtual device resources. A storage system includes a storage device and a processor. The processor manages a primary volume and a snapshot volume as a snapshot family. The processor uses a snapshot virtual device as the data storage destination for the primary volume and for the snapshot volume. Upon receiving a write request from a host, the processor switches between an overwrite process and a new allocation process in accordance with the reference made to a write destination address range by the snapshot volume and with the degree of distribution of the write destination address range in the snapshot virtual device. The overwrite process is performed to overwrite an allocated area of the snapshot virtual device. The new allocation process is performed to allocate a new area of the snapshot virtual device to the write destination address range.Type: ApplicationFiled: March 13, 2024Publication date: December 26, 2024Inventors: Yoshihiro YOSHII, Tomohiro YOSHIHARA, Takashi NAGAO, Ryosuke TATSUMI

Patent number: 11782603Abstract: A bandwidth between a second processor and a second memory is higher than a bandwidth between a first processor and a first memory. The first memory stores a read command from a host computer. The first processor analyzes a content of the read command, and in accordance with a result of the analysis, requests read data from the second processor. In response to the request from the first processor, the second processor reads the read data from one or more storage drives and stores the read data in the second memory. The second processor notifies the first processor that the read data is stored in the second memory. The first processor transfers the read data read from the second memory, to the host computer without storing the read data in the first memory.Type: GrantFiled: March 9, 2022Date of Patent: October 10, 2023Assignee: Hitachi, Ltd.Inventors: Kentaro Shimada, Takashi Nagao, Naoya Okada
