4 Networking considerations The network configuration for the StoreOnce single node systems and the StoreOnce multi node systems has some significant differences. Since the StoreOnce multi node product supports autonomic failover, more care is required in the network configuration to ensure optimal operation of the autonomic failover feature. The network configuration is done as part of the HP installation process for the multi node system. Be sure to read the appropriate section in this chapter for your model. But first there are some considerations that are common to all models. Common networking considerations The Ethernet ports are used for data transfer to iSCSI VTL devices, StoreOnce Catalyst and CIFS/NFS shares and also for replication data transfer and management access to the StoreOnce Web and CLI Management Interfaces. NOTE: The HP StoreOnce B6200 Backup system does not support iSCSI VTL devices. Configured backup devices and the management interfaces are all available on all network IP addresses configured for the appliance. In order to deliver best performance when backing up data over the Ethernet ports it will be necessary to configure the appliance network ports, and also backup servers and network infrastructure to maximize available bandwidth to the StoreOnce device. Supported Ethernet configurations The HP StoreOnce Backup system supports a wide range of network configurations. The following list summarizes configuration details. • An Ethernet connection is required for backing up to NAS shares, Catalyst stores or iSCSI VTL devices (not B6200), and replication/Catalyst copy activities, and for all StoreOnce management tasks via the GUI or CLI. • The HP StoreOnce Backup system supports IPv4 only. • DHCP and static IP addressing are supported on single-node systems. • The multi-node B6200 system supports static IP only. • For single node products, networking parameters are contained within a network configuration file. ◦ For ease of installation, a default configuration file is supplied with the StoreOnce Backup system. As long as LAN port 1 of the appliance is connected to a DHCP-enabled 1GbE network switch, the HP StoreOnce Backup system will be immediately active on the network after installation. The user then has the option of continuing to use the default configuration file or creating and activating an additional configuration file that is tailored to their exact networking requirements. NOTE: 100 Base-T Ethernet will limit performance. ◦ Users who do not have a DHCP-enabled 1GbE network must create and activate a network configuration file before their system can become active on the network. This network configuration file may use any available Ethernet port, but one must always be connected, even if you are only using the FC ports to back up and restore data to the HP StoreOnce Backup system. This is because the network is used to access the StoreOnce Management Console remotely; it is also used for replication. Common networking considerations 27

4 Networking considerations
The network configuration for the StoreOnce single node systems and the StoreOnce multi node
systems has some significant differences. Since the StoreOnce multi node product supports autonomic
failover, more care is required in the network configuration to ensure optimal operation of the
autonomic failover feature. The network configuration is done as part of the HP installation process
for the multi node system.
Be sure to read the appropriate section in this chapter for your model. But first there are some
considerations that are common to all models.
Common networking considerations
The Ethernet ports are used for data transfer to iSCSI VTL devices, StoreOnce Catalyst and CIFS/NFS
shares and also for replication data transfer and management access to the StoreOnce Web and
CLI Management Interfaces.
NOTE:
The HP StoreOnce B6200 Backup system does not support iSCSI VTL devices.
Configured backup devices and the management interfaces are all available on all network IP
addresses configured for the appliance. In order to deliver best performance when backing up
data over the Ethernet ports it will be necessary to configure the appliance network ports, and also
backup servers and network infrastructure to maximize available bandwidth to the StoreOnce
device.
Supported Ethernet configurations
The HP StoreOnce Backup system supports a wide range of network configurations. The following
list summarizes configuration details.
•
An Ethernet connection is required for backing up to NAS shares, Catalyst stores or iSCSI VTL
devices (not B6200), and replication/Catalyst copy activities, and for all StoreOnce
management tasks via the GUI or CLI.
•
The HP StoreOnce Backup system supports IPv4 only.
•
DHCP and static IP addressing are supported on single-node systems.
•
The multi-node B6200 system supports static IP only.
•
For single node products, networking parameters are contained within a network configuration
file.
◦
For ease of installation, a default configuration file is supplied with the StoreOnce Backup
system. As long as LAN port 1 of the appliance is connected to a DHCP–enabled 1GbE
network switch, the HP StoreOnce Backup system will be immediately active on the
network after installation. The user then has the option of continuing to use the default
configuration file or creating and activating an additional configuration file that is tailored
to their exact networking requirements.
NOTE:
100 Base-T Ethernet will limit performance.
◦
Users who do not have a DHCP-enabled 1GbE network must create and activate a network
configuration file before their system can become active on the network. This network
configuration file may use any available Ethernet port, but one must always be connected,
even if you are only using the FC ports to back up and restore data to the HP StoreOnce
Backup system. This is because the network is used to access the StoreOnce Management
Console remotely; it is also used for replication.
