Root Complex Connections
(Four Processor Modules)
This diagram illustrates the root complex connections between
the four processor modules and the 16 PCIe I/O slots in a fully-populated
server. Each CPU supports two I/O root complexes. Each root complex
connects to two I/O slots through two of five multiplexing switches.
The port ID values shown in the diagram correspond to the pci@ values
reported in the OpenBoot show-devs command output. For
