Allows you to plan and transition from FC or FCIP acceleration solutions to IOA. This is because
these acceleration solutions will likely be deployed at the core switches already and will allow for
a smooth transition to IOA.
Facilitates planning the capacity based on WAN ISL throughput on the core switches themselves.
Provides optimal routing as the flows have to traverse these core switches to reach the remote sites.
