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

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

Indiana Spatial Data storage.iu.edu/DOQQS Contents include

USGS data Cities/counties IDNR maps

Formats include MrSID TIFF
