Dhcp And Static Ip Addressing; Hp D2D On A Gigabit Ethernet Network; Connecting To A Business Server On The Main Network - HP StorageWorks D2D100 - Backup System User Manual

• High Availability Dual Port Configuration: Both network ports are used, but the two ports are bound
together.
Single port configuration is the default mode, but it may easily be changed from the Web Management
Interface. If dual port configuration is required, the networks must be on different sub-nets.
The High Availability mode is the recommended option, because it provides port failover and increased
bandwidth, but both network ports must be connected to the same switch and it must support port bonding.

DHCP and static IP addressing

DHCP network addressing is enabled by default as long as you are connecting the HP D2D as an IPv4
device; this means that an IP address and other network settings are assigned automatically when you
connect the HP D2D Backup System to an IPv4 network that has a DHCP server. If preferred, you can use
static IP addressing and assign settings manually during the installation process. If you are connecting to
an IPv6–only network, it is normally sufficient to enter the IPv6 MAC Address (found on the label on the
top of the unit) when running the Installation Wizard.
The HP D2D Backup System should be on the same logical and physical 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.

HP D2D on a Gigabit Ethernet network

The HP D2D Backup System is connected to a spare port on an existing Gigabit network switch.
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 need to be backed up.
The configuration, illustrated in
assuming that Gigabit networking is already in place, and requires no additional hardware. 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 traffic is unlikely to be a problem.

In some environments, backup data is kept separate from day-to-day office network traffic, as illustrated
in Figure 13 on page 34. There is a separate, dedicated IP network for all hosts that need data to be
backed up.
