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

• 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!)

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 -gt 30-90 second to start transfer.)
• File size chunks of 10Mb or greater work best
  (tar/zip files)
