Abstract

Subaru telescope of National Astronomical Observatory of Japan is now under the commissioning phase, and there will be installed seven powerful instruments to produce several tens megabytes of data in each second of observations. The total amount of the storage necessary to keep those data becomes about 20TB per year.Here we introduce a concept of the hierarchical data storage system on the super computer system of Hilo Base Facility of Subaru Telescope. Detailed description of the computer system and performance feature is also presented. The computer system is useful for operation support based on advanced information management database, called Subaru Data Base.
