A Scalable Real-time Data Management System

Current Navy initiatives such as a standard sonar system (TB-29 towed array) for all submarine classes, Integrated Undersea Surveillance Systems and SURTASS ships, and continued development and installation of Acoustic Rapid COTS Insertion sonar systems are increasing the size of archived acoustic data at an exponential rate. This petabyte size growth will further exasperate the usability of the current tape based archives by the community of users in the Navy. Fortunately, as the cost of disk storage declines and clustering technology matures, there is an opportunity to build disk based digital archive systems that are 100 per cent online, thus offering Naval operational benefits such as faster tactical response to intelligence requests, analyst access to data without temporal linear access delays and real time tape data transfer delays. Here, we propose to develop a scalable real-time data management system (SRDMS) for Navy sonar processing applications. Our solution is built upon our scalable disk based distributed Linux cluster archive storage management system technology - Archivas. SRDMS will seamlessly integrate with existing ONI Common Acoustic Sensor Data Exchange. SRDMS will enable the data collected by submarines and their off-board sensors to be available to joint forces and national agencies.
