VLAN guidelines
There is a fixed number of available physical NIC ports on the StoreOnce System, defined by
the number of 1 GbE ports plus 10 GbE ports, therefore there is a limit on the number of physical
Subnets to which the StoreOnce System can be directly connected. If your network requires
more Subnets than this—for example, twenty—the network administrator can define 20 VLANs,
each with its own Subnet and, typically, use a 10 GbE bonded link to the StoreOnce System as
a trunk.
To do this, the network administrator sets up the switches with the necessary VLANs and identifies
20 tags. (The tag values can be any integer between range 2-4094.) The ports on the network
switch to which the StoreOnce System connects must be trunked and tagged. Then using the
StoreOnce CLI or GUI, the HPE StoreOnce administrator modifies the network configuration by
first defining the Port Set for the physical 10 GbE link and making it VLAN enabled, and then
configuring each of the twenty VLAN Subnets to use that Port Set.
The following VLAN guidelines apply:
The user can configure up to a total of 128 different VLAN Subnets on each StoreOnce
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.
