Title: Naoshi Maniwa: Innovator in Distributed Systems

Introduction

Naoshi Maniwa is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of distributed systems, holding a total of 5 patents. His work focuses on enhancing transaction control systems and optimizing data migration processes.

Latest Patents

One of his latest patents is a "Distributed transaction control system and distributed transaction control method." This innovative system includes redundant coordinator apparatuses that manage input votes from participant apparatuses. The determination part of the system replaces input votes with votes of preparation failure when timeouts occur. It makes a commitment decision when all input votes are successful and initiates a rollback if any input vote indicates failure. The system's consensus processing part then decides on the final outcome through distributed consensus, notifying participant apparatuses of the settlement result.

Another notable patent is the "Method for selecting a page for migration based on access path information and response performance information." This method involves multiple storage apparatuses that provide a virtual logical volume composed of various logical pages. A management computer determines the target logical page for data migration based on access path information, actual volume response performance, and storage destination information. This ensures that the volume goal performance is achieved efficiently.
