Root Complex
Connections (Two Processor Modules)
This diagram illustrates the root complex connections between the two processor modules and
the 16 PCIe I/O slots in a half-populated server. Each CPU supports two I/O root
complex fabrics. Each root complex connects to four 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 showdevs command
output. For example:
