    1. Advanced IT to Support Digital Libraries Research and Academic Computing & Telecommunications DivisionsUITS

    2. IT Resources thru UITS • Research & Academic Computing – Data(Gerry Bernbom, Director) • Distributed Storage Services Group(Anurag Shankar, Manager) • Advanced Visualization Lab (Eric Wernert, Manager/Sr. Scientist) • Telecommunications - Data Network Services (Terry Usrey, Director) • Advanced Networking Services (Jim Williams, Manager) • Digital Media Network Services (Collaboration)(Doug Pearson, Manager)

    3. Storage Resources • Four tape robots (two at IUB, two at IUPUI) • 540 TB total storage (~75TB used) • Services • Massive Data Storage – temporary or archival storage of files 50MB or greater • Common File System – transparent access to files • Andrew File System – remote collaboration and sharing

    4. Storage – A Sense of Scale • 2 Kilobytes : A typewritten page • 5 Megabytes : Complete works of Shakespeare OR 30 seconds of TV quality video • 1 Gigabyte (1000MB) : 1 pickup truck filled with paper OR a symphony in high-fi sound • 1 Terabyte (1000GB) : All the X-ray films in a large hospital OR paper from 50,000 trees • 10 Terabytes : The printed collection of the US Library of Congress • 50 Terabytes : The contents of a large mass store system • 8 Petabytes (8000TB) : All information available on the web • 200 Petabytes : All the printed material (in the world!)

    5. Storage Infrastructure

    6. Is it right for your collection? • Development Resource? – Yes! • Data security, backup • Digitize data at higher resolution/fidelity than currently practical to deliver • Delivery Resource? – Maybe • Hierarchical storage (metadata on disk, data on tape -> 30-90 second to start transfer.) • File size – chunks of 10Mb or greater work best (tar/zip files)

    7. Storage Example Indiana Spatial Data • storage.iu.edu/DOQQS • Contents include • USGS data • Cities/counties • IDNR maps • Formats include • MrSID • TIFF

    8. Visualization Resources IBM T221 Display • 22” LCD panel • 3840 x 2400 pixels = 9.2 Mpixels = 204 DPI • Uses/Benefits • Very high-res imagesand manuscripts • Side-by-side comparisonof images • Minimize panning and zooming

    9. Visualization Resources Tiled displays and rendering clusters • Very high resolution (18.6 Mpixels) • Distributed rendering on PCs • Uses/Benefits • High-resolution images or video • Big data visualization, large geometry sets • Multiple independentviews (of same data)

    10. Visualization Resources Co-located haptics display • Provides force and tactile feedback to supplement visuals • Uses/Benefits • Small artifact exploration • Physical simulations • Accessibility technology

    11. Visualization Resources Immersive & Semi-immersive displays • Includes new portablepassive stereo display • Uses/Benefits • Large-format, 3D (stereo) exploration • Sense of presence,scale, or immersion • Natural interaction

    12. Desktop Visualization • New technologies are more affordable, but not pervasive • Scalable 3D applications • Web-based • Desktop • Advanced Displays • Collaboration • Application Sharing • Teleconferencing • Collaborative On-line Worlds (ActiveWorlds)

    13. Data Network Services • General Network Connectivity • Special Services • Quality of Service (QoS), Multicast, etc. • Advanced Networks • State: iLight • National: Abilene (Internet 2 backbone) • International: Global NOC (TransPAC, EuroLink, etc.)

    14. Data Network Services Campus Networking

    15. Data Network Services

    16. Data Network Services

    17. Digital Media Network Services Collaboration Support • Video Conferencing Tools • Polycom network throughout IU system • 64 port Multipoint Control Unit • Bridges to other technologies outside IU • Video/audio streaming and recording • Desktop Collaboration • Netmeeting & other technologies
