- at current fill rates, the silos would be full in ~6 months
- options are to add a silo or go to higher density drives. The latter seems most sensible to start. 5 TB drives (T10000-C) exist for 1/2 the price per TB as the 1 TB ones. A drive runs $22k. Lance guesses we would need 8 drives to be worthwhile. We currently have 47 drives; capacity in the existing 2 silos is 128.
- he will be talking to folks at other labs (notably LLNL) who have experience with them. We will also need to do a few upgrades (ACLS, firware and HPSS) before the new drives can be used
- in about 3 years, 10 TB drives should be available. Apparently they will be able to read and write the 5 TB tapes (and write at 10 TB density, I believe)
- For the SCSC:
- when does the decision to go with 5 TB drives happen
- how will we pay for them
- in the meantime, groups needing tapes on shorter than a 6 month leash should go 1 Tb (PPA is ordering 1800 of them now).
