3 Connecting to your network

IMPORTANT:
Please take time to read this chapter before completing the Network checklist later in this document,
see Network requirements (page
Each couplet is a paired combination of two nodes that are directly connected in failover pairs. If
one node fails, the system is designed to failover to the other node without any external interaction
from the customer. The B6000 Series Backup System uses a concept called a Virtual Network
Interface (VIF) to make this possible.
In very simple terms:
The physical IP addresses relate to the physical ports that are used to connect the HP B6000
Backup System to the customer's network
The Virtual Network Interface (VIF) addresses are the IP addresses that the customer uses to
connect to the B6000 Management Console and to target backup and replication jobs.
Because these are never directly linked to a physical port they continue to function correctly
in the event of node failure.
For a more detailed discussion of how VIFs and IP addresses are used see

What is currently supported

IPv4 is supported.
DNS is supported.
A maximum of two sub-nets is supported, which can be used as follows: one sub-net for data
(NAS shares and replication) and one sub-net for management.
Only one gateway is supported. If you wish to configure two sub-nets, make sure that the
gateway is on the same sub-net as the network that requires access to remote sites.
NAS shares and replication data use the same Ethernet channel.
If you wish to use your Ethernet channel for replication only, the only supported backup option
is to create VTL libraries on Fibre Channel.
The network configuration applies to all nodes in the cluster. For example, you cannot have
separate network configurations for each rack in a two-rack system.

What is not currently supported

IPv6 is not supported.
DHCP is not supported.
There is no VTL support on Ethernet using the iSCSI protocol.
LACP is not supported.

Factory default cabling

The HP B6000 Series Backup System contains an internal 10GbE and 1 GbE private network.
This comprises two HP ProCurve 1GbE/10GbE network switches per 4–node cluster. There is a
1GbE connection to the iLO3 network interface on each node. This network is for internal data
path failover and management traffic only. There is no user access permitted to this network.
The network configuration is probably the most complex aspect of installation.
