For a multiple switch fabrics in which initiators on one switch communicate with targets on another, the same principles apply as shown in Figure 3-2. The “A” port initiators and E_Ports are grouped together on one I/O blade with connections to the corresponding “A” port targets and E_Ports on the same I/O blade on the second switch. “B” port initiators, targets, and links are connected in a similar way.
