Project Title: Development of Mirror Server by using High Speed Data Transfer in Genome Science Project Description DNA/protein biological sequence database is essential for advanced studies in genome research. These sequence data have been mutually collected between US, Japan and Europe since 1984. Software search engines such as FASTA/BLAST are used to find homology sequences. These require huge local disks to store these databases. Some mirror servers have been developed to provide most recently updated data for DNA/protein biological sequence database. In present, however, these servers often fail due to the lack of existing network band width. In this project, we will develop a reliable mirror server with high speed data transfer in HPIIS. In genome research the data of DNA database have been being increasing tremendously, including about 10% of Japanese contributions. However existing servers are mainly mirroring only US data to Japan. Therefore a bidirectional mirror server is to be helpful to update advanced data collected including in other countries and deliver them to researchers. This mirror server could not establish without a high-speed and reliable connection.
