Turner Studios is the full-service production division of the Turner Entertainment Group and the largest production company of its kind. Turner Studios produces entertainment shows, commercials, documentaries and live sports for leading providers such as CNN, TCM, TNT, Boomerang and Cartoon Network. Its commitment to entertainment excellence is exemplified by the 50 awards its work has averaged annually over the last four years.
Turner Studios success led to a critical challenge - safeguarding its work. Every week, the studio’s users generate large multimedia files that must be stored and backed up. Relying on robotic tape libraries for back-ups due to their low cost per-GB presented a challenge. With their limited I/O capabilities, the tape drives ran constantly to keep pace with the flow of production data. Moreover, restoring files was arduous. To retrieve a file, the entire monthly back-up of the file’s directory had to be restored followed by incremental restores of snapshots until the day the file was last saved. Administrators tried virtual tape libraries which provided faster I/O speeds, but retrievals of files still remained difficult…
A proposal based on ZFS, 20 off JetStor® SATA 516F 16-bay RAID Arrays and QLogic FC switches linking the arrays was selected.
