Understanding PCIe Root Complex Connections
All 16 PCIe slots support PCIe cards with the following characteristics:
■
Hot-plug low-profile adapters
■
x8 Gen1, x8 Gen2, and x8 Gen3 cards
Note - If you install a 16-lane card in any slot, electrical support is provided to the card's lowest
8 lanes.
A root complex is the CMP circuitry that provides the base to a PCIe I/O fabric. Each PCIe I/
O fabric consists of the PCIe switches, PCIe slots, and leaf devices associated with the root
complex. Understanding the relationship of the PCIe root complexes to the PCIe I/O fabrics
will help you properly assign devices when configuring Oracle VM Server for SPARC logical
domains.
These topics explain the root complex configurations:
