SCSI and VTL libraries
SCSI libraries have automated robotic mechanisms to move tape media from a fixed number of library slots to devices for read or write operations. The number of slots can typically vary between 2 to 10,000 and the number of devices can be between 1 to 100 or more.
Traditionally, libraries are physical units with mechanical robotics, however the same functionality can also be provided by virtual tape libraries (VTLs) that emulate this functionality. VTLs can also be configured and used as Autochangers.
The robotic controller and associated tape devices are always all controlled through a SCSI interface which is available on one or more storage hosts.
