Chapter 4: System Configurations
This configuration consists of four racks, eight system modules, and 32 Node boards. As
Figure 4-8 shows, all of the available Router ports are now in use. The 64P configuration
is the largest one that can be supported using the Rack Router board. To go beyond 64P,
requires the use of a meta router chassis. With a meta router, configurations of up to 128P
are possible (see Figure 4-9).
