Migrating to converged fabrics
In a one-hop architecture, converged traffic goes from a server to a switch that splits it to Ethernet and Fibre
Channel. In two-hop architecture, converged traffic goes to a second switch before the split. The more
switch hops in a DCB-enabled network, the more difficult it is to keep the network operating at peak
efficiency while minimizing congestion. Figure 11 shows the expected industry path to convergence.
