Title: Toshiaki Hatanaka: Innovator in Data Migration Technology
Introduction
Toshiaki Hatanaka is a notable inventor based in Odawara, Japan. He has made significant contributions to the field of information processing systems, particularly in data migration technologies. With a total of 3 patents to his name, Hatanaka's work has had a considerable impact on how data is managed and transferred in modern computing environments.
Latest Patents
One of Hatanaka's latest patents is a method, apparatus, and computer program for controlling data migration in an information processing system. This invention involves a central processing unit (CPU), a new storage system connected to the CPU, and an old storage system connected to the new storage system. The method allows for data migration to transfer data from the old storage system to the new one while permitting access by the CPU during the process. The invention intelligently determines whether the CPU's access is to a region where data migration has been completed or not. If the access is to a completed region, the new storage system handles the processing. Conversely, if the access is to an incomplete region, the old storage system processes the request, facilitating the transfer of data. The speed of data migration can be adjusted based on resource utilization and the priority of access by the CPU.
