Research and Academic Computing & Telecommunications DivisionsUITS


It resources thru uits l.jpg
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)


Storage resources l.jpg
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


Storage a sense of scale l.jpg
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!)



Is it right for your collection l.jpg
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)


Storage example l.jpg
Storage Example

Indiana Spatial Data

  • storage.iu.edu/DOQQS

  • Contents include

    • USGS data

    • Cities/counties

    • IDNR maps

  • Formats include

    • MrSID

    • TIFF


Visualization resources l.jpg
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


Visualization resources9 l.jpg
Visualization Resources
