This secondary storage system will enable Audi to perform backup, archiving and file serving tasks without risking capacity bottlenecks. Problems were primarily caused by the number of files to be processed and the system speed. Once disks had reached a certain capacity but file traffic continued, migra-tion of the file system to the robots could take hours. The system's weak points were both its HSM software and its tape robots. Finding a higher-performance solution was critical.
Data securing applies to the whole open systems segment.
Three million files with a volume of around 800 GB are secured daily. Audi's total securing set currently comprises around 250 million files, equivalent to about 37 terabytes. The daily migrations file serving volume for the Technical Development Division is between 250 and 600 gigabytes, sometimes exceeding one tera-byte. This division stores a total of around 11 TB of active data in the disk cache and the robot system. Archiving, which has a current volume of around 3 TB, comprises files known as vehicle control cards, a form of documentation for each vehicle that includes all production docu-ments with a mandatory storage period of 15 years.
