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
