Port mapping
The FC SAN Module uses port-mapped pre-provisioned routes to direct traffic from the blade server
(HBAs) to the fabric. When you first turn on the module, by default, the internal ports (F_Ports) are
mapped to a set of predefined external ports (N_Ports). For the default port mapping, see Table 3
on page 5. See t “Remapping ports” on page 5 if you want to change the default mapping. Figure 2
shows a mapping with eight internal ports (F_Ports) evenly mapped to four external ports (N_Ports).
External ports connect to the same fabric through different Edge switches.

Table 2 provides a description of the port mapping in Figure 2.
