I/O Connections to CMP/Memory

Modules

Each PCIe slot and onboard I/O device is connected to one CMP module. Device

address is dependent on system configuration. See CMP Number on page 168 and

CMP Number on page 169 for more information.

If a CMP module fails, the onboard devices and slots directly connected to it become

unavailable. Recovery of the I/O services connected to the failed CMP requires I/O

node reconfiguration.

For example, in a 4P system, if CMP0 goes offline, the following devices become

unavailable:

■ PCIe0

■ PCIe1

■ Onboard hard drives

In this failure scenario, the system is unable to boot from internal drives.

Similarly, if CMP1 goes offline, the following devices become unavailable:

■ PCIe4

■ PCIe5

■ Onboard network devices
