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
