(Palmer, Alaska) in 1994, the idea of a terabyte (TB) of data seemed baffing in its magnitude. Nineteen years later, Newman's precision geospatial survey frm has collected data around the globe and serves clients from offces on three continents with increasingly advanced technology. TerraSond now deploys equipment that ingests raw data at the rate of gigabytes per hour and processing software that renders it in dozens of formats. Its servers now hold more than 50 terabytes of data collected from more than 15 countries. Data of a volume that once seemed unimaginable is now very real and presents major challenges. "Visually organiz- ing two decades worth of survey work in a single place is no easy task," said Newman. "We've spent a considerable amount of time, effort and money seeking an effcient way to manage the data itself." TerraSond's IT department has grown in sophistication and capability over the years, but a comprehensive approach to managing and sharing data of extreme volumes has been elusive. As complexity grew, TerraSond began to look to software and server-side solutions from enterprise vendors and consultants. After months and tens of thousands of dollars invested in researching possibilities, they sought a different approach.
