DHCP and static I
Paddressing
DHCP network ad
dressing is enabled by default, which mea ns that an IP address and other network
settings are assigned automatically when you c onnect the HP D2 D Backup System to a network that has
a DHCP server. If preferred, you can use static IP addressing and assign settings manually during
the installation process.
In both instanc
es, the HP D2D Backup System should be on the same logical and phys ical network as the
host machine connecting to it. This is normally the case because, typically, the HP D2D Backup System is
connected to the same Gigabit network switch as the host machines backing up to it.
Optional Tape Attach
A tape drive may be attached directly to your H P D2D Backup System, allowing you to store backups
offsite. Please refer to “Attaching a physical tape drive” on page 29 for further details.

This may
be your main network, which is also used to connect a number of different types of devices,
such as PCs, servers, workstations and printers, or a dedicated backup network that is used solely
for clients that ne ed to be backed up.
The confi
guration, illustrated in Figure 7 on page 25, is the simplest and most common configuration,
assuming that Gigabit networking is already in place, and requires no additional h ardware. The only
disadvantage to the configuration is that a high volume of traffic may impact network performance during
backup and backups may take longer to complete. However, if backups are scheduled to run outside of
normal business hours, the volume of data trafficisunlikelytobeaproblem.
