HP StoreOnce VSA Backup System User Guide (TC458-96025)

Network model with StoreOnce software version 3.11.0 and later
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
• One Management VIF address must be configured for StoreOnce 6500 and B6200 Backup
systems; this is the VIF address that will be used to access the StoreOnce Backup system GUI
and CLI.
• At least one portset must be configured. A portset defines the physical ports that will be
connected to the network switch, 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 still available and how they are bonded. The portset applies to all
nodes in the cluster and ports must always be bonded on StoreOnce 6500 and B6200 Backup
systems.
• Each portset will have at least one subnet. If the portset is VLAN enabled it may be configured
with multiple VLAN subnets. See VLAN subnets with StoreOnce Backup (page 143) for more
information about guidelines when creating VLAN subnets.
The following diagram provides a simple overview of the hierarchy within a network configuration.

Bonding modes
Mode 1 (Active-backup)
One port of the pair is active, the other port is in a backup state. If the active port or connection
is lost, the backup port will become the new active port. This mode provides fault tolerance.
Mode 4 (LACP)
