Supported Ethernet Configurations; Ethernet Network Connection; Ipv4 And Ipv6 Network Protocols; Dual Network Ports - HP StorageWorks D2D100 - Backup System User Manual

NOTE:
The Web Management Interface is used to configure devices and it requires an Ethernet connection.
LAN Port 1 (the lower LAN port on the rear of the HP D2D) must always be connected, even if you are
using the FC ports to back up and restore data to the HP D2D.
NOTE:
The HP D2D also supports direct connection of a monitor and keyboard. Please refer to

IPv4 and IPv6 network protocols

The HP D2D supports both IPv4 and IPv6. Setup and configuration will default to IPv4, if the
network is configured to support it. On 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. However, if this does not work, you can use the system console, as described in
"Using the system console to discover the HP

Dual network ports

The two physical network ports provide three network configuration modes:
• Single Port Configuration: The HP D2D is connected to one network only; only one network port
is used (Port 1).
• Dual Port Configuration: The HP D2D is connected to two different networks. Both network ports are
used. If dual port configuration is required, the networks must be on different sub-nets.
• High Availability Dual Port Configuration: The HP D2D is connected to a single network. 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. The High Availability mode is the recommended option, because it provides port failover and
increased bandwidth, but the network switch 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.
