Stacking For High Availability Topologies - Lenovo RackSwitch G8264 Application Manual

Stacking for High Availability Topologies

© Copyright Lenovo 2016
A stack is a group of up to eight RackSwitch G8264 devices that work together as a
unified system. Because the multiple members of a stack acts as a single switch
entity with distributed resources, high‐availability topologies can be more easily
achieved.
In Figure 58, a simple stack using two switches provides full redundancy in the
event that either switch were to fail. As shown with the servers in the example,
stacking permits ports within different physical switches to be aggregated
together, further enhancing switch redundancy.
