Target aggregation

Access Gateway mode is normally used as host aggregation. In other words, a switch in AG mode

aggregates traffic from a number of host systems onto a single uplink N_Port. Similarly, many targets

can be aggregated onto to a single uplink N_Port, as shown in the figure below. Target aggregation has

many applications. As one example, you can consolidate targets with various lower Fibre Channel

speeds (such as 1, 2, or 4 Gbps) onto a single high-speed uplink port to the core fabric. This reduces

the number of core fabric ports used by target devices and allows higher scalability.
