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.
