Virtual Tape Storage

A virtual tape storage or virtual tape library (VTL) presentation allows the storage space on these hard
drives to appear to the backup application as tape cartridges (DLT or LTO). Data is stored on the hard drives
through an interface that appears as a tape library, with virtual cartridges, virtual drives, and a virtual
changer mechanism. A DXi4700 with a VTL or Multi-Protocol configuration can be configured to present
multiple VTL interfaces of different sizes and types at once.This allows backup applications to recognize and
integrate a DXi series system into a data center environment just like one or more physical tape libraries.
