Note This topology illustrates a single fabric only. In a dual fabric, the second fabric is an exact replica of this
topology, and the concepts that are described in this document are applicable to the second fabric as well.

Fabric—A physical topology of switches interconnected by Fibre Channel or FCIP ISLs.
IOA Site—Represents a set of switches within the physical fabric that is in a specific physical
location. Multiple IOA sites within the physical fabric are typically interconnected over a MAN or
WAN using Fibre Channel or FCIP links. IOA provides the acceleration service for flows traversing
across sites. As a part of the IOA configuration, the switches must be classified into appropriate IOA
