Stack Deployment Model
In the data center network shown in Figure 2-1, stacks are deployed on the access, aggregation, and core layers to form a simple and loop-free network.
- On the access layer, low-cost CE8800&7800&6800&5800 series switches are deployed to set up a stack. Terminals (servers or other network devices) are dual-homed to the stack to ensure high reliability of access links.
- On the aggregation/core layer, high-performance CE12800&12800E series switches are deployed to set up a stack, which connects to access devices through inter-chassis links to form a loop-free network.
