What is the maximum number of LSCs that can be stacked together?

The maximum number of LSCs that can be stacked together is three. This configuration is established to optimize performance while ensuring system integrity. Each LSC (Local Session Controller) in the stack can effectively manage resources, load balance traffic, and provide redundancy. Stacking three LSCs allows for a balance between redundancy and performance, ensuring that if one unit fails, the other two can continue to operate without significant disruption.

Moreover, having more than three units in a stack may lead to complexity in management and could introduce potential bottlenecks, undermining the overall efficiency. Understanding the stacking limit is crucial for designing robust systems that can handle varying levels of traffic while maintaining high availability and reliability.
