Dual Port mode Use this mode if: Servers to be backed up are split across two physical networks which need independent access to the D2D appliance. In this case virtual libraries and shares will be available on both network ports; the host configuration defines which port is used. Separate data (―Network SAN‖) and management LANs are being used, i.e. each server has a port for business network traffic and another for data backup. In this case one port on the D2D can be used solely for access to the Web Management Interface with the other used for data transfer. Network configuration, dual port mode In the case of a separate network SAN being used, configuration of CIFS backup shares with Active Directory authentication requires careful consideration, see Network Configurations for CIFS AD on page 15 for more information. 13

Dual Port mode
Use this mode if:
Servers to be backed up are split across two physical networks which need independent access to the D2D
appliance. In this case virtual libraries and shares will be available on both network ports; the host
configuration defines which port is used.
Separate data (―Network SAN‖) and management LANs are being used, i.e. each server has a port for
business network traffic and another for data backup. In this case one port on the D2D can be used solely for
access to the Web Management Interface with the other used for data transfer.
Network configuration, dual port mode
In the case of a separate network SAN being used, configuration of CIFS backup shares with Active Directory
authentication requires careful consideration, see
Network Configurations for CIFS AD
on page 15 for more
information.
