Abstract

As the clock speed of CPU is increased and broad band network has been prevailed, the demand for high data rate storage has been emphasized. In addition to it the demand for long life data storage has been increased because lots of important digital data has been accumulated in various organizations. Hard disks are one candidate for the recording media. However, life time of the hard disk drive is about five to ten years. The cluster drive using optical disk drive is realistic solution for archival server. The archival servers are usually used as storing archival data and supplying data for research use. Because non-stop operation is possible with optical disk cluster drive, the data which is not used anymore can be removed from archival server to off-line data warehouse without stopping the optical cluster drive. This paper describes structure and performance of such archival server.
