Diagram 1:  Resilient Core

Virtual Chassis Stacking (VCStack) - Resiliency and Stability

Today's enterprises rely 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, starting with a resilient network core. The SwitchBlade x908 provides the ideal solution - without the expense of a 
full chassis. 

Using VCStack at the core of 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. 

The above diagram 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.

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. 

With the benefits of high availability, increased capacity and ease of management, VCStack makes networking reliable and simple.
