A Fault-Tolerant Architecture for Supporting Large Scale Digital Libraries
Mariella Di Giacomo, Mark Martinez, Jeff Scott, Rick Luce · Issues in Science and Technology Librarianship · 2003
At the Research Library of Los Alamos National Laboratory (LANL), we have developed an affordable multi-terabyte redundant RAID system -- running on Linux -- that addresses the needs of a constantly growing demand for electronic journals, conferences and standards. Although there are several practical issues associated with systems supporting electronic content -- such as acquisition, archiving, access and cataloging -- this paper will focus on archiving and providing access to electronic journals. This article explains the design and development of a scalable, fault-tolerant and affordable system, presents an overview of the architecture, summarizes the problems and architectural issues encountered, and describes the technical solutions adopted.
