Example Network Environment - HP StoreOnce 2700 Installation And Configuration Manual

The following guidelines apply:
The user can configure up to a total of 128 different VLAN Subnets on each StoreOnce Backup
system; the VLAN Subnets may be consecutive or non-consecutive.
The user can configure all VLAN Subnets on one Port Set or divide the VLAN Subnets over
multiple Port Sets.
It is not permitted to configure VLAN Subnets on a Port Set that uses Mode 6 network bonding.
Each VLAN tag interface is configured using the VLAN ID index, which is the same as the
switch VLAN ID number and must be an integer from 2 to 4094.
Each VLAN tag interface can configured for use with one IPv4 and one IPv6 subnet.
For example, if a VLAN tag ID was configured for use with ports eth 0 and eth1 on IPv4, it
can also be configured for use on IPv6 with that Port Set but it cannot be used with any other
Port Set.
The user can add/delete/modify the VLAN network configuration without interrupting
non-affected network configuration on the appliance.
VLAN tagging does not increase bandwidth because the bandwidth is bound by the physical
speed of the Port Set. The number of open streams is bound by the specification for the
StoreOnce appliance.
StoreOnce monitoring is on the physical Port Set, not on each VLAN Subnet.
VLAN tagging is not a multi-tenancy solution. Once configured, all StoreOnce services can
bind / listen to all VLAN Subnets. For example the NAS shares are available on all configured
Subnets, and permissions are required to regulate access to shares.

Example network environment

In the following example the following Port Sets are configured on the StoreOnce Backup system:
eth0 is the Quick Install connection that was created by connecting LAN port 1 at installation.
It uses DHCP and is not VLAN enabled. If required, it can be reconfigured with static IP
addresses.
eth2 and eth3 are used for the StoreOnce Catalyst Copy and Replication Subnet and provide
the default gateway to the WAN. This Port Set is also not VLAN enabled and is configured
to support one IPv4 Subnet. It uses the 1 Gbit ethernet ports, Port 3 and Port 4. If required,
one IPv6 subnet could be configured on this Port Set after installation.
eth4 and eth5 are used for Backup Subnets. This Port Set is VLAN enabled and currently
supports two VLAN Subnets — one IPv4 subnet and one IPv6 subnet. Further IPv4 and IPv6
VLAN Subnets may be configured on this Port Set, as required, up to a maximum of 128. The
Port Set uses the 10 Gbit ethernet ports, Port 1 and Port 2.
eth1, (the 1 Gbit ethernet port, Port 2), is available to support a further Port Set. (Some HP
StoreOnce Backups systems provide four 10 Gbit ethernet ports, and eth6 and eth7, (the 10
Gbit ethernet ports, Port 3 and Port 4) may also be configured to support further Port Sets.
However, these ports are not available on all models.)
NOTE: The availability and number of 10 Gbit ethernet ports depends upon the model of
StoreOnce Backup system.
