Latest Patents

Kahori Sugihara holds a patent for a "Storage system, storage management method, and storage management program." This invention aims to minimize the amount of writing data to storage devices while solving the write hole problem. The storage system includes computers, nonvolatile storage devices, and high-speed storage devices that can be accessed more quickly than the other storage devices. A drive log containing write log information is recorded in the high-speed storage device. When a write request is received, the computer first performs drive log check processing before proceeding to data write processing. If a redundant write log record is found, the computer updates its status to 'completed' before continuing. If no redundant record is found, the data write processing occurs without altering the drive log or write log information.
