This illustration is a schematic diagram of a typical NDMP copy-enabled virtual tape library (VTL). The VTL is represented as a box containing the following items:

- NDMP input/output channel link to TCP/IP

- TCP/IP connected to each of two NDMP Servers

- FC input/output channel link to Fiber Channel

- Fiber Channel connected to VTD

- NDMP Server connected to VTD

- VTD (virtual tape drive) connected to Virtual Tapes data storage

- NDMP Server connected to Tape

- Tape connected to Tape Library
