  1. Digital Preservation Infrastructure in the University of Alberta Libraries Peter Binkley Digital Initiatives Technology Librarian peter.binkley@ualberta.ca

  2. Before…

  3. During…

  4. After • Sun STK5800 (Honeycomb)

  5. STK5800 • Network-attached storage (NAS) • Raw capacity: 26 tb; usable: ~22 tb • Mean time to data loss: ~1.4 million years • EOL’ed… • Opensource software being developed by a third party: Dewstream > TierraCloud

  6. SAM-FS • Sun Storage Archive Manager • Policy-place data placement • Continuous backup

  7. Architecture

  8. SAM-FS Storage

  9. Parameters and bottlenecks • Preservables vs keepables vs backup • How far offsite, and how to get it there?

  10. Concerns • Heavy-duty infrastructure – spinning disks use lots of power and create lots of heat • Successor to the STK5800 • Preservation of metadata: how do you preserve it if it won’t hold still? • Staffing: appropriate level of monitoring and checking

  11. Future • Ongoing expansion • Cloud storage? • Trusted Digital Repository (TDR) • Broader collaboration
