HP StoreOnce Backup - Manual (Page 143)

This is Dynamic Link Aggregation mode, using the LACP protocol. It creates aggregation groups
that share the same speed and duplex settings.
Mode 6 (Balance-alb)
This is adaptive load balancing. This includes balance-tlb and receives load balancing (rlb) for
IPv4 traffic.
There are some restrictions to these bonding modes:
•
Bonded ports must operate at the same speed: 1GbE ports cannot be bonded with 10GbE
ports.
•
Each port can be part of only one subnet (unless VLAN Tagging is enabled on that port).
•
A subnet’s IP address range may not overlap with any other subnet
VLAN subnets with HP StoreOnce Backup
There is a fixed number of available physical NIC ports on the HP StoreOnce Backup system,
defined by the number of 1GbE ports plus 10GbE ports, therefore there is a limit on the number
of physical subnets to which the HP StoreOnce Backup system can be directly connected. If your
network requires more subnets than this—for example, twenty—the network administrator can
define 20 VLAN subnets, each with its own unique VLAN Tag ID and, typically, use the 10GbE
bonded link to the HP StoreOnce Backup system as a trunk.
To do this, the network administrator sets up the switches with the necessary VLAN subnets and
configures a unique VLAN tag index for each subnet. (The tag values can be any integer between
range 2-4094.) The ports on the network switch to which the StoreOnce Backup system connects
must be trunked and tagged.
Using the StoreOnce CLI, the HP StoreOnce administrator modifies the network configuration by
first defining the portset for the physical 10GbE link and making it VLAN enabled, and then
configuring twenty VLAN subnets to use that portset.
VLAN guidelines
IMPORTANT: VLAN subnets are only used for data. It is not permitted to configure VLAN subnets
on a portset that is used for Management.
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 up to 128 different VLAN subnets on one portset or divide the 128
different VLAN subnets over multiple portsets.
•
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 be part of one network subnet only and cannot be used more
than once.
For example, if a VLAN tag ID was configured for use with port eth 0 and eth1, it cannot also
be configured for use with any other portset.
•
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 portset. The number of open streams is bound by the specification for the
StoreOnce appliance.
•
StoreOnce monitoring is on the physical portset, 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.
