Abstract :
Recently TRW fielded a prototype system for a government customer. It provides a wide range of capabilities including data collection, hierarchical storage, automated distribution, data analysis, and product dissemination of imagery information. The system is capable of processing thousands of data sets and storing over 400 Gigabytes (GB) of data per day. Over 100 users are supported in a distributed system covering eleven geographical areas. The development effort spanned two years and involved the integration of over 200 COTS/GOTS products. The data that is collected, stored, and disseminated is composed of large image file data sets (from 700 MB to three GB per data file) and associated metadata. Initial customer requirements of a two-year retention window and access latency of less than ten seconds dictated three-tier storage architecture
