Diagram 2 shows link aggregation between the core VCStack
and edge switches. With link aggregation across ports on
different virtual chassis members, there is no perceptible
disruption in the case of a link failure, and the full bandwidth of
the network is available. Link aggregation is also used to connect
network resources, such as servers, across the virtual chassis
members. This ensures device and path resiliency.
Fast failover between stack members provides for an almost
uninterrupted network service. In a VCStack environment, one
of the stack members acts as the master switch, and provides
decision making for the virtual chassis. All of the other VCStack
members are in active standby, also having learnt routing and
forwarding information for the network to ensure that if the
master were to fail, another member is able to seamlessly
assume control of the virtual chassis with minimal network
downtime. Failover and recovery can be completed in as little as
three seconds.
Allied Telesis also includes long distance stacking in the VCStack
solution. Long distance stacking enables the VCStack solution
to provide a distributed network core. The increased distance
provided by ber stacking connectivity means that members
of the virtual chassis do not have to be co-located, but can be
kilometres apart.
All of the benets and powerful features of VCStack remain
exactly the same – Allied Telesis long distance stacking provides
a genuine distributed virtual network core.
The powerful VCStack solution offers uninterrupted network
access and high availability of critical resources, and yet is very
simple to manage with almost plug-and-play conguration.
Whether your virtual chassis is located in the same equipment
rack, or distributed across the campus, VCStack provides
resiliency, scalability and ease of management.
