CHAMPAIGN, IL -- Legato Systems, Inc. (NASDAQ:LGTO), today announced that NCSA (the National Center for Supercomputing Applications), located at the University of Illinois at Urbana-Champaign, has expanded its DiskXtender(R) Unix Edition (DX-Unix) license capacity from 500 terabytes to 1.5 petabytes. The center's data storage needs are currently growing at a rate of 20 to 40 terabytes per month, with the average file size ranging from megabytes to gigabytes and continuing to double each year. "Because we anticipate growing our storage to one petabyte or more by next year, we are planning ahead and creating processes so the growth does not overwhelm our organization," said Michelle Butler, technical program manager at NCSA. "By expanding our Legato solution, we are able to cost-effectively manage this data growth and continue to provide the storage with performance and computing power for our users to be successful in their research programs." With one of the largest high-performance computing facilities in academia, NCSA serves researchers from academic institutions and Fortune 500 companies. The center works with government agencies, communities and educational institutions to help them utilize high-performance computing and new technologies in ways that benefit society. DX-Unix provides NCSA users with fast, efficient and transparent access to mission-critical information. By virtualizing primary and secondary storage into an `infinite disk,' DiskXtender enables administrators to increase their storage capacity almost without limitation. It also leverages existing storage assets and reduces complexity to help lower the total cost of data ownership. "NCSA is an important supercomputing resource for many different areas of research and development," said Amena Ali, senior vice president of Marketing for the Management Solutions Group, Legato. "This research generates and uses an enormous amount of information that must be securely stored and easily accessed. Legato is proud to help the NCSA effectively manage its storage so it can focus on the goals and objectives of its research."
