HP StoreOnce 6500 Backup Installation Planning and Preparation Guide

Figure 2 Network example
The following guidelines apply:
• The user can configure up to 128 different VLAN subnets for the StoreOnce Backup system;
the VLAN subnets may be consecutive or non-consecutive.
• VLAN subnets are only used for data. It is not permitted to configure StoreOnce Management
on a VLAN subnet.
• The user can configure up to 128 different VLANs on one subnet or divide the 128 different
VLANs over multiple subnets.
• Each VLAN subnet 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 can be part of one VLAN subnet only and cannot be used more than once.
For example, if a VLAN tag ID was configured for use with ports eth0 and eth1, it cannot also
be configured for use with any other portset.
• Users can add/delete/modify the VLAN network configuration without interrupting non-affected
network configuration on the appliance.
• VLAN tagging does not increase the interface bandwidth because the bandwidth is bound
by the physical speed of the portset. VLAN tagging does not control the number of open
streams per interface/s. The number of streams is bound by the specification for the StoreOnce
model.
• StoreOnce monitoring is on the portsets, 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 must be configured to regulate access to the shares.
