Search for large-scale file systems needs to be fast, scalable, and security aware. By partitioning search indexes along security lines, we enable immediate elimination of parts of the file system a user cannot see. This significantly speeds up search, while preventing statistical attacks which might reveal information about hidden documents. Our research indicates that for most users and groups, only a small fraction of the file system is available, making the effective cost of search under our scheme equivalent to that of a much smaller file system.

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.

PDSI Organization

The Petascale Data Storage Institute is led by Carnegie Mellon University. The PDSI institutions are:

  • Carnegie Mellon University
  • Lawrence Berkeley National Laboratory and the National Energy Research Scientific Computing Center
  • Los Alamos National Laboratory
  • Oak Ridge National Laboratory
  • Pacific Northwest National Laboratory
  • Sandia National Laboratory
  • University of California, Santa Cruz
  • University of Michigan
