PCIe Card Slot Configuration and Numbering
The server supports the PCIe 16-lane format. PCIe card slots connect to root complexes in
CMPs that are mounted on CMIOUs. For more information about PCIe device root complexes,
refer to the SPARC M8 and SPARC M7 Servers Administration Guide.
Each CMIOU has three slots, each of which can hold a single PCIe x16 card carrier. The slot
numbers repeat from 1 to 3 in each CMIOU, so to identify the physical location of a card
you must specify the CMIOU number, as well as the card slot number. Note that the physical
numbering for card slots starts at 1 (not 0) and ends at 3 (not 2).
Note - In a PDomain, if a CMIOU fails, the DCU will lose access to the failed CMIOU PCIe
slots.
