PCIe Root Complex Connections (Single-
Processor Configurations)
In single-processor configurations, the server configures the PCIe root complex paths to this
topology.
This diagram illustrates the root complex connections between the two CPUs in PM0 and 14
PCIe I/O slots.
Note - I/O slots 15 and 16 cannot be used in single-processor configurations.
CPUs 0 and 1 support four root complex fabrics, which connect to the 12 usable I/O slots
through switches 0 through 3.
