Latest Patents

Yuhyeon Bak's latest patents include groundbreaking technologies that significantly enhance data storage efficiency. The first patent, titled "Apparatus and Method for File Level Striping," introduces a novel file level striping method that improves the file creation interface within file systems. This method extends the inode structure by including a last disk ID field, which initializes when files are created. It tracks physical block allocations based on last disk ID, enhancing the management of file I/O requests. Bak's design ensures that a volume manager can logically organize multiple disks, enabling better utilization of storage resources.

The second patent, "Raid System and Mapping Method Thereof," focuses on creating an efficient RAID (Redundant Array of Independent Disks) environment. This system incorporates at least two disks and utilizes memory to store a striping zone information table that converts physical addresses into logical addresses. The CPU plays a crucial role by modifying the striping zone information whenever a new disk is integrated into the storage medium. This innovation allows for seamless data writing and reading processes, improving overall system performance.
