"In this work, we introduce two archival policies tailored for the
tape storage system that will be available on BlueWaters. We also
show how to adapt the well known RAIT strategy (the counterpart of
RAID policy for tapes) for BlueWaters."
※Tape Related Hardware
Tapes [約 500000本]: Each tape stores up to 1TB of uncompressed data
Tape Drives [約 500台]
Tape Libraries [約 3台]
Mover Nodes [約 50台]
