The IMI Colloquium in April
Application of the mathematical science techniques to the research of storage systems

• In this IMI Colloquium, we held three lectures about “Application of the mathematical science techniques to the research of storage systems“.

Speaker：Masayuki Yamamoto (Manager, Data Storage Systems Research Dept, Yokohama Research Laboratory, Hitachi, Ltd.)
Title：Storage systems and the research outline
Speaker：Takaki Nakamura (Research Institure of Electrical Communication, Tohoku University)
Title：A proposal of risk-aware replication to improve data availability under wide-spread disasters
Speaker：Hiroaki Akutsu (Data Storage Systems Research Dept, Yokohama Research Laboratory, Hitachi, Ltd.)
Title：Technology of Data Relocation Process in Automated Storage Tiering Functions

Place：Lecture Room L-1 (3F, IMI, Kyushu University)

The first presenter, Masayuki Yamamoto, gave a brief introduction of their company, Hitachi, Ltd., described technology trends of storage systems, and pointed out academic theories and fields which will become more important to develop the next generation storage systems. The second presenter, Takaki Nakamura, addressed the problem of a storage system on the Internet which can survive even in wide-scale disaster. He showed the formulation of the problem, methods for solving it, and results of computational experiments. The third presenter, Hiroaki Akutsu, presented various modeling and computational problems related to automatic hierarchical functionality of storage systems using SSD, SAS HDD, and SATA HDD. In the question time and even after the session, we had held active discussions, especially with specialists in optimization in our institute.

Attendance: about 50
