The CSIRO ASKAP Science Data Archive

Astronomy is moving into the era of "big data", a paradigm where data volumes will be reaching 10s of PBs (ASKAP), and in the near future 100s of PBs (SKA1). Science from the next generation of radio telescopes requires long term storage of the data and tools for querying and accessing the data. At CSIRO we have addressed this by building the CSIRO ASKAP Science Data Archive (CASDA) to provide long term storage for Australian SKA Pathfinder (ASKAP) data products, and the hardware and software facilities that enable astronomers to access the data. CASDA will store ∼5 PB per year from ASKAP and serve that to astronomers around the world using both virtual observatory (VO) and web-based portal services.
