Title: Jun Matsuda: Storage Systems Inventor

Introduction

Jun Matsuda is an inventor based in Odawara, Japan, whose work focuses on storage systems and cache management. Matsuda is associated with Hitachi, Ltd. and is credited with 2 patents.

Latest Patents

Matsuda’s listed patents address storage control and the management of cache capacity when a storage controller accesses devices connected through another controller.

“Storage system with cache threshold control” describes a system in which a first storage controller handles host requests for data stored on a device managed by a second controller. The first controller uses cache memory to temporarily store data and sets a capacity threshold for the cache assigned to the storage device, based on that device’s properties.

“Storage control system and storage control method” presents a related approach to preventing cache overload when access to an external storage device is persistently or temporarily slow. It likewise uses a threshold based on the storage device’s properties to manage the cache capacity assigned to that device.

Career Highlights

Matsuda’s patent work reflects an emphasis on reliable data handling across interconnected storage controllers. The inventions describe ways to manage cache resources while responding to host requests, including when external storage access performance is limited.

Collaborations

Mikio Fukuoka and Keishi Tamura are listed among Matsuda’s coworkers at Hitachi, Ltd.

Conclusion

Jun Matsuda’s patents focus on controlling cache capacity in multi-controller storage systems, helping address performance and resource-management challenges in data storage.
