HP StoreOnce B6200 Installation Planning and Preparation Guide (EJ022-90995, November 2013)

Some examples
• Customer has a 10GbE and a 1GbE network and only wants data to be accessible remotely:
Use Template 1, but configure one gateway only to the 10GbE network for data
• Customer has a 10GbE and a 1GbE network and wants both data and management to be
accessible remotely: Use Template 1 and configure two gateways. Decide whether data or
management should use the 'default' gateway.
• Customer has a 10GbE or a 1GbE network only and wants data and management to be
accessible remotely: Use Template 2, 3 or 4, as appropriate and configure one gateway.
• Customer has a 10GbE or a 1GbE network only and does not want data or management to
be accessible remotely: Use Template 2, 3 or 4, as appropriate and do not configure a
gateway.
NOTE: For software revision 3.3.0 and greater: if the customer wants to have only two 1GbE
network connection from each node in a couplet to their Ethernet switches, they should use Template
5 instead of Template 2 in the above examples.
IP address range
The total 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. In the following examples you will find the recommended number of IP addresses. For a
more detailed explanation of VIF addresses and how IP addresses are assigned across couplets,
see Understanding VIF addresses (page 13).
IMPORTANT: As long as the recommended number of IP addresses is allocated during the network
configuration process, the B6000 Backup System will automatically assign IP addresses for all
nodes in the system when the network is initially configured or additional couplets are added. If
you do not supply the recommended number and subsequently expand your system, you will need
to reconfigure the network and also reconfigure the addresses used for backup and replication
targets.
Reserved IP address range
The HP StoreOnce Backup System uses the 10.154.x.x ip range for its internal network. This means
that this IP address range is not available for the customer's network. It may cause conflict and
unpredictable results if a customer network uses the 10.154.x.x ip range.
Template 1, uses 10 GbE and 1 GbE sub-nets
Template 1 supports users who have a 10GbE network and a 1GbE network and wish to use
separate sub-nets for data and management. The gateway must be in the same sub-net as the
network that is being used to connect to remote sites. This is normally the data path network.
The default bonding mode for this template is Mode 1 on both sub-nets.
The recommended IP address range is 25 in total: 16 contiguous on the data sub-net; 1 + 8
contiguous on the management sub-net.
NOTE: When using a 10GbE network, you must provide the correct SFPs for your environment.
They are not supplied with the product.
