Understanding Virtual Interface (Vif) Addresses; Physical Ip Ports - HP StoreOnce B6000 Series Planning And Preparation Manual

The cabling required to connect to each switch is pre-installed. The cabling to each node is shown
in the following diagram. The ports illustrated are reserved for use with the internal network switch.
CAUTION:
the customer network to the internal network switches at the top of the racks.

numbered on the rear of the node.

Understanding Virtual Interface (VIF) addresses

To understand the IP address allocation on supported configurations (called templates and described
below), it is important to understand the difference between Physical IP ports and Virtual (VIF)
addresses.
To summarize:
You should ensure that you have sufficient IP addresses to cover both the physical port
connections and the virtual connections that the HP StoreOnce Backup System generates during
network configuration.
The number of IP addresses that you require depends upon the template that you select (and
its implementation of physical ports and VIF addresses), and the number of couplets that you
have installed.
It is strongly recommended that you allocate sufficient IP addresses to support a fully expanded
two-rack system (with 8 nodes). This means that the network does not need to be re-configured
if you start with a one-rack system and subsequently expand it.
If you have to re-configure your network, you must also re-configure backup targets and
replication configurations.

Physical IP ports

The physical ports are the ports that are used to connect the HP StoreOnce Backup System to
the customer's network.
Two 10GbE and four 1GbE ports are available on each node for connecting to the customer's
Ethernet network(s).
Physical ports are always bonded and a physical IP address is required for each external
bonded Ethernet port. Once the HP service engineer has configured your network, the physical
IP addresses are subsequently used for HP support purposes only.
