Petascale Data Storage Institute @ UC Santa Cruz

UC Santa Cruz has developed techniques that can prevent unauthorized users from accessing data stored in petabyte-scale file systems. Our approach guards against both external intruders and internal users who might be able to compromise a few disks. Built on the Ceph infrastructure, our security system is much faster than previous approaches, reducing overall file system performance by only a few percent.

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
