Key Solution - Virtual Chassis Stacking (VCStack)
VCStack - Resiliency and Stability
Today's modern Enterprise business relies on Information Technology resources and applications to access business-critical information, and for
day-to-day work. A high-availability infrastructure is now of paramount importance. The Allied Telesis x600 series switches provide the ideal
solution with VCStack.
Using VCStack in your network allows multiple switches to appear as a single virtual chassis. In normal operation, this virtual chassis acts as a
single switch, simplifying management.
Diagram 3 shows link aggregation between the core VCStack and the 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. Fast Failover ensures
absolutely minimal network downtime in the event of a problem.
VCStack and link aggregation provide a solution where network resources are spread across the virtual chassis members, ensuring device and path
resiliency. Virtualization of the network core ensures access to information when you need it.
