The I/O layout of the x3950 X6 server is essentially the same as the x3850 X6, just with twice

the components.

The I/O subsystem is directly attached to a processor.

Socket 1 (the CPU book closest to the Storage Book) is responsible for the ML2 slot, Slot

9 and Slot 12.

Socket 2 is responsible for Slots 7- 8 and Slot 11.

Both sockets 1 and 2 drive their respective I/O through the Primary I/O Book.

Socket 3 is attached to Slots 4-6, and Socket 4 is connected to slots 1-3.

Slots 1-6 are configurable in how they present I/O. In the case of the FH/HL I/O Book, this

is presented as 1x16 slot and two x8 slots. For the FH/FL I/O Book, this configuration is

presented as 2x16 slots and 1x8 slot.

You can opt for any combination of the two possible I/O Books.

In an eight-socket configuration, Socket 1 is in the bottom node.

Table 6 shows the processor and PCIe slot association.
