Sun STK5800 (Honeycomb)
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
SAM-FS
Sun Storage Archive Manager Policy-place data placement Continuous backup
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
