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.
This table shows the root complex topology that is in effect
in single-processor configurations:
