| Abstract: |
Subaru Telescope has been operating the Hyper Suprime-Cam (HSC)
instrument since 2014. This wide-field camera produces between 300GB
and 1.2TB of data per night, depending on the science program. Subaru
needed to make some large adjustments in both software for managing data
flows and techniques for managing the data storage to handle the huge
increases in data size and storage requirements compared to earlier
instruments.
We present our experience with managing the storage pool using HSC, the
techniques for minimizing problems associated with potential storage
failures and describe the software for managing data flows within the
observatory and managing the storage pool itself. |
