5 Network configuration, understanding the StoreOnce

Network configuration basics
HP StoreOnce Backup systems support both IPv4 and IPv6 address protocols. IPv4 is available for
backup to all target devices, for replication and StoreOnce Catalyst Copy, and for appliance
management. IPv6 is supported for backup to StoreOnce Catalyst stores, replication and Catalyst
Copy, and for appliance management. It cannot be used for backup to VTL or NAS shares. All
systems also support DHCP (v4 and v6).
Network configuration components
The network is defined in a single network configuration with three main components: DNS server
settings, Port Set settings and Subnet settings. The key points to understand when creating or
modifying the configuration are described below.
Up to three DNS servers (one primary, and two backup servers if the primary is unavailable) may
be configured for the StoreOnce Backup system. These may have IPv4 and/or IPv6 addresses and
apply across all Port Sets and Subnets defined within the configuration.
In order to use FQDNs "Fully Qualified Domain Names" rather than an IP address to access the
StoreOnce system, the DNS server addresses that you provide should be able to resolve addresses
for all configured subnets. If you are using IPv4 and IPv6 addressing, then DNS servers configured
need to be able to resolve both IPV4 and IPV6 FQDNs.
DNS Server and Gateway addresses will not be acquired in the following Subnet
VLAN Tag Enabled Subnet configured
Addressing mode set to DHCP with the expectation of acquiring IPv6 address details
DHCPv6 Server is running on a Windows Server operating system
In this configuration it is possible to manually provide the DNS Server and Gateway addresses
that should have been acquired via DHCPv6.
