6 Network configuration, understanding the StoreOnce
networking concepts

the StoreOnce CLI commands to configure the network go to

Network configuration

The network is defined in a single network configuration that is created using StoreOnce CLI
commands. The key concepts to understand when creating or modifying the configuration are:
Up to three DNS servers may be configured for the StoreOnce Backup system
At least one portset must be configured. A portset defines the physical ports that will be
connected, their bonding mode, the type of data that they will carry, and whether they are
VLAN enabled. Further portsets may be defined, depending upon the number of physical ports
available and how they are bonded.
Each portset will have at least one port and one subnet. If the portset is VLAN enabled it may
be configured with multiple VLAN subnets (maximum is 128 for the whole system). See
subnets with StoreOnce Backup (page 42)
VLAN subnets.
Subnets define the network paths used by clients to access the StoreOnce Backup system for
Backup and Management, and the network path that is used for StoreOnce Catalyst Copy
and Replication.
The parameters specified for the subnet are unique to that subnet; you may use DHCP in one
subnet and static addressing in another.
If multiple subnets are defined, one (and only one) subnet must always be designated as the
default gateway for routing traffic to IP addresses that are not within the configured subnets.
StoreOnce software version 3.1 1.0 also provides support for Data In Flight Encryption using
the IPsec protocol.
The following diagram provides a simplified overview of the hierarchy within a network
configuration.
