The Distributed-Parallel Storage System (DPSS) is a scalable, high-performance, distributed-parallel data storage system orginally developed as part of the DARPA -funded MAGIC Testbed, with additional support from the U.S. Dept. of Energy, Energy Research Division, Mathematical, Information, and Computational Sciences Office.
The DPSS is a data block server, which provides high-performance data handling and architecture for building high-performance storage systems from low-cost commodity hardware components. This technology has been quite successful in providing an economical, high-performance, widely distributed, and highly scalable architecture for caching large amounts of data that can potentially be used by many different users.
Current performance results are 980 Mbps across a LAN and 570 Mbps across a WAN.

DPSS Integration:

We are currently working on integrating the DPSS into serveral computational grid-like tools.
These include the following:

Globus

SRB (Storage Resource Broker)

DPSS Applications

A Medical Imaging application using the DPSS and ImgLib

Terravision: The terrain navigation program that was the initial target application for the DPSS.

DIV : A large image viewing application from the EROS Data Center.

A High Energy Physics data processing application.
Most of these applications are examples of the Wide Area Large Data Object architecture (WALDO) that we have been developing.
