Appendix B Rules for System Configuration B-3
I/O unit (IOU) 1 2 Each IOU contains the following:
PCI cards—Four short PCI Express (PCIe)
slots (four upper slots) and one short PCI-
X slot (lowest slot).
One I/O controller (IOC) chip, which is
the bridge chip between the system bus
and the IO bus.
Inter-integrated circuit (I2C) components
for environmental monitoring.
PCIe switches or bridges connected to the
slots.
You can also add an optional IOBOX, which
contains additional PCIe slots or PCI-X slots.
An IOU requires a CPUM and MEMB on the
same XSB in order to be used. In the case of
quad-XSB, the slots on an IOU are divided up
among the first two parts of a quad-XSB. The
assignments cannot be changed. A separate
CPUM and MEMB are required on each part
of the quad-XSB in order to access the slots of
the IOU assigned to the parts of the quad-
XSB.
