Supported DDS Configurations

The NDMP NAS Option supports two fundamental DDS configurations:

• One or more NAS servers connected to the SAN that share a tape drive or TLU, and the Arcserve Backup server is connected to the SAN.
• Two or more NAS servers connected to the SAN that share a tape drive or TLU, and the Arcserve Backup server is not connected to the SAN.

The following diagram shows an example of one or more NAS servers connected to the SAN that share a tape drive or TLU, and the Arcserve Backup server connected to the SAN.
