Logical Layout of a FOX Ring
A FOX network is physically connected as a ring; however, it is logically configured
with the Expand subsystem as a fully connected mesh (that is, each cluster is only one
logical hop from any other cluster in the FOX network). Figure 1-1 shows the physical
and logical layout of a FOX ring with four clusters.
