This design is especially useful for large, multi- cluster installations. As with a regular core- edge, the edge switches can be of any size. As you can see in Figure 1- 3 on page 7, we have attached the SVC to each of four independent fabrics. For obvious reasons, you must storage devices with at least four ports with this design, although it is not required. Core Switch Core Switch ...
