Abstract This paper focuses on distributed storage technologies and backing up data onto remote data centers because of growing sense of disaster recovery for large scale disaster. Now the authors are constructing widely distributed storage environment among Kanazawa University, Hiroshima University, National Institute of Informatics (NII). This environment is characterized by high performance of random I/O access. Because every site can access to same data, IT services can be continued with live migration technology. In this paper, the authors evaluate performances of storage I/O and wide area live migration on this storage environment.
