Regular Agenda Items

  • Jennifer Russell, leading the IT Projects group, introduced herself. She is interested in also helping with the project management of scientific computing projects as well.

Lance Nakata told us about the state of the tape silo:

  • 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.
  • 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).

We had a discussion on the planned CD review process. We came to the idea of having a full up external review sometime next year ("spring?") and working our way up to it with incremental looks at current systems with targeted internal documentation and reviews. These could then form the basis for the big review.
