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 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 -> 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

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

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 independent views (of same data)

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

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

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)
