history
History
  • Similar to most academic libraries
  • Library manages library infrastructure
  • Average growth in technology needs
  • Investment in high-end SAN solution
  • Moving happily along…
  • Until…

LOC - Storage Architectures for Digital Collections

unt digital library program
UNT Digital Library Program
  • Sudden growth in digital content acquisition
    • Web archiving
    • Digitization projects
    • Born digital content
  • Unknown growth patterns
  • Unplanned system architectures

interim solutions
Interim Solutions
  • Scale out existing infrastructure
    • Not scalable at growth rate because of $$$
  • Build R&D infrastructure using new technologies
    • PetaBox infrastructure
    • Low-end SATA arrays
    • Great for R&D but weren’t adequate for production services

regrouped efforts
Regrouped Efforts
  • Define needs based on real patterns
  • Collaborative partnership with UNT Library Core IT services and Digital Library
  • Give and take on both sides
    • Moved to write once digital object model
    • Data spread across logical volumes and nodes
    • Just in time lookup of digital object locations
    • Abstract storage in application logic instead of overcoming with complex storage architectures

current solutions
Current Solutions
  • Large investment in Dell SATA based iSCSIInfrastructure ( MD3000i – 500 TB)
  • Arrays have different configurations based on need (6 different arrays)
  • Different RAID configuration based on system and data integrity needs (RAID-5, RAID-6 primarily)
  • Add new storage volume to DL environment, don’t grow existing volumes
  • Rebalance digital objects as storage arrays are replaced
  • Replicate across systems with technology neutral replication framework

next step
Next Step
  • Scale it up!!!
  • Invest in geographically separate replication location:
    • Tape infrastructure
    • iRods
    • Not managed by UNT (hopefully)
