ViStor Virtual Tape Library

ViStor is a software product that emulates the behavior of tape libraries and uses disk as its primary storage. Your existing backup software interacts with ViStor in just the same way as you use a tape library. ViStor can be configured to emulate several different tapes drives and libraries ensuring that your backup product will recognize the device.  ViStor can be configured to have many virtual tape drives. This is ideal when you have several lower performance data sources but want to get a high aggregate throughput by having multiple machines backing up to the different ViStor drives.

Instead of using costly Fiber Channel or SCSI, ViStor uses standard IP networking hardware leveraging your existing infrastructure. For SAN like performance, you can use Gigabit Ethernet network at a fraction of the cost of a Fiber Channel SAN network. This is done through a protocol called iSCSI.  The VTL was designed to using kernel mode drivers ensuring you will get the optimum performance for your backups.
