Finding files becomes increasingly challenging as storage capacities grow. Browsing through folders or using keyword search tools become much less effective when such techniques must handle ever-increasing numbers of files, perhaps up to a trillion within one file system. To address this problem, UC Santa Cruz researchers are exploring new approaches to search and indexing within file systems. Our location-based search technique considers spaces defined within adjustable link-distances from an origin, similar to searching for people within social networks, thus narrowing down a gigantic space to a more manageable one.

The Storage Systems Research Center (SSRC) is part of the Petascale Data Storage Institute, a Department of Energy-funded institute exploring techniques to make high-performance storage faster and more usable.

PDSI Research at UC Santa Cruz

PDSI topics the SSRC is investigating include security for petascale storage, new approaches to distributed metadata, the use of storage class memories in high-performance systems, and archival storage.
