• Hosts and targets should be in separate port groups.
• Direct target attachment configurations are not enforced.
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 Figure 15. 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.
