Paper Abstract

A distributed digital archive system configured with dual archive devices (two archive servers, two database servers and two 680-Gbyte optical libraries) that provides fault-tolerant image archival has been implemented for the Radiology Department at UCLA. Digital images from various radiologic imaging devices are transmitted via Ethernet and FDDI networks to archive servers, where images are archived to optical disks and distributed to remote display stations or the print station via 1-Gbit/sec high-speed UltraNet network. The dual configuration of the system provides non-interrupt archive operations in the event of failure of any of the archive components. Once a failed device is detected, the system automatically re-configures itself so that all images are routed to the second equivalent device and archived. The global Ethernet network serves as a backup for the FDDI and UltraNet networks. In the even of FDDI or UltraNet failure, all images can be transmitted across the Ethernet. The system archives 1.5 to 2.0 Gbytes of data per day and provides inter-sectional image referencing throughout the department.
