Architecture
SAM-FS Storage
Parameters and bottlenecks Preservables vs keepables vs backup How far offsite, and how to get it there?
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
Future Ongoing expansion Cloud storage? Trusted Digital Repository (TDR) Broader collaboration
