I/O Root Complex Connections
I/O Root Complex Connections
SPARC T8 servers use a dedicated chip (IO Hub) to host the PCIe fabric. Each IOH chip has
five root complexes, four are sixteen lanes wide (x16), and one is eight lanes wide (x8). The
root complexes are divided up and assigned to all of the I/O devices in the server. The SPARC
T8-2 server contains two IOH chips. Each IOH chip connects to four of the PCIe slots. The
following table describes the device paths for the server.
The
pci@
values reported in the OpenBoot
show-devs
command output are paths in the I/O root
complex topology.
