    1. 1. Advanced IT to Support Digital Libraries Research and Academic Computing & Telecommunications Divisions UITS
    2. 2. IT Resources thru UITS <ul><li>Research & Academic Computing – Data (Gerry Bernbom, Director) </li></ul><ul><ul><li>Distributed Storage Services Group (Anurag Shankar, Manager) </li></ul></ul><ul><ul><li>Advanced Visualization Lab (Eric Wernert, Manager/Sr. Scientist) </li></ul></ul><ul><li>Telecommunications - Data Network Services (Terry Usrey, Director) </li></ul><ul><ul><li>Advanced Networking Services (Jim Williams, Manager) </li></ul></ul><ul><ul><li>Digital Media Network Services (Collaboration) (Doug Pearson, Manager) </li></ul></ul>
    3. 3. Storage Resources <ul><li>Four tape robots (two at IUB, two at IUPUI) </li></ul><ul><li>540 TB total storage (~75TB used) </li></ul><ul><li>Services </li></ul><ul><ul><li>Massive Data Storage – temporary or archival storage of files 50MB or greater </li></ul></ul><ul><ul><li>Common File System – transparent access to files </li></ul></ul><ul><ul><li>Andrew File System – remote collaboration and sharing </li></ul></ul>
    4. 4. Storage – A Sense of Scale <ul><li>2 Kilobytes : A typewritten page </li></ul><ul><li>5 Megabytes : Complete works of Shakespeare OR 30 seconds of TV quality video </li></ul><ul><li>1 Gigabyte (1000MB) : 1 pickup truck filled with paper OR a symphony in high-fi sound </li></ul><ul><li>1 Terabyte (1000GB) : All the X-ray films in a large hospital OR paper from 50,000 trees </li></ul><ul><li>10 Terabytes : The printed collection of the US Library of Congress </li></ul><ul><li>50 Terabytes : The contents of a large mass store system </li></ul><ul><li>8 Petabytes (8000TB) : All information available on the web </li></ul><ul><li>200 Petabytes : All the printed material (in the world!) </li></ul>
    5. 5. Storage Infrastructure
    6. 6. Is it right for your collection? <ul><li>Development Resource? – Yes! </li></ul><ul><ul><li>Data security, backup </li></ul></ul><ul><ul><li>Digitize data at higher resolution/fidelity than currently practical to deliver </li></ul></ul><ul><li>Delivery Resource? – Maybe </li></ul><ul><ul><li>Hierarchical storage (metadata on disk, data on tape -> 30-90 second to start transfer.) </li></ul></ul><ul><ul><li>File size – chunks of 10Mb or greater work best (tar/zip files) </li></ul></ul>
    7. 7. Storage Example <ul><li>Indiana Spatial Data </li></ul><ul><li> </li></ul><ul><li>Contents include </li></ul><ul><ul><li>USGS data </li></ul></ul><ul><ul><li>Cities/counties </li></ul></ul><ul><ul><li>IDNR maps </li></ul></ul><ul><li>Formats include </li></ul><ul><ul><li>MrSID </li></ul></ul><ul><ul><li>TIFF </li></ul></ul>
    8. 8.
