1 High-performance slot that is directly connected to the processor module. The connectors in these slots are differently colored than the slots from the PCIe3
switches.
2 Slots P1-C2 and P1-C8 have Gen4 x16 connectors, but will only function as Gen4 x8.
3 Enabling the I/O adapter enlarged capacity option will only affect Linux
Capacity setting should be disabled.
Notes:
• The peak bandwidths supported by the x16 slots are 16 gigabytes per second (GBps) in simplex mode and 32 GBps in duplex mode.
• The peak bandwidths supported by P1-C3, P1-C4, and P1-C9 slots are 32 GBps in simplex mode and 64 GBps in duplex mode.
• The peak bandwidths supported by P1-C2, P1-C5, P1-C6, P1-C7, P1-C8, P1-C10, P1-C11, and P1-C12 slots are 16 GBps in simplex mode and 32 GBps in
duplex mode.
• All slots support enhanced error handling (EEH).
• All PCIe slots are hot swappable and support concurrent maintenance.
Slot descriptions for the 9009-41A, 9009-42A, or 9223-42H
The 9009-41A, 9009-42A, and 9223-42H systems provide PCIe3 and PCIe4 slots. Table 5 on page 5
provides information about the PCIe slots in the 9009-41A, 9009-42A, and 9223-42H systems. The
9009-41A system offers one POWER9 processor module. The 9009-42A and 9223-42H systems offer
two POWER9 processor modules. The PCIe slots are enabled to support the PCIe3 cable adapter (FC
EJ08 or EJ20) that is used to attach the EMX0 PCIe Gen3 I/O expansion drawer.
