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
CMPs in 2P systems on page 164
and
TABLE: Devices controlled by CMPs in 4P
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
