storage resources
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
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
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
