Research and Development on Highly-functional and Highly-available Information Storage Technology
　During and immediately after the Great East Japan Earthquake, many information servers were lost, resulting in the disappearance of resident registry information and medical information, which revealed the vulnerability of the existing storage systems against disaster. This is attributable to the fact that conventional availability has been dependent in many cases on multiplexing at the site (such as RAID technology). Damage to the site itself and long-term power failure caused by tsunamis and fire were not considered.

Highly-available Storage Systems
　The first priority for this development is to improve the availability of information by distributing each storage system. We should calculate quantitatively the risk of a disaster in the specific area, and then develop advanced storage systems with high-availability to minimize the loss of information adaptively.
