FIGURE 73 Full nine-mesh topology
Core-edge topology
You can also connect the Brocade DCX 8510 Backbones in a core-edge topology. For example, Figure
74 shows six chassis connected in a core-edge topology (four edges and two cores).
Although Figure 74 shows only the Brocade DCX 8510-8, each chassis can be either a Brocade DCX
8510-4 or a DCX 8510-8. You can have up to eight edges with DCX 8510-8 cores or up to four edges
with DCX 8510-4 cores.
Each line in Figure 74 represents four QSFP cables. The cabling scheme should follow the parallel
example shown in Figure 70 on page 485.
