PCIe adapter placement rules and slot priorities for the 9006-12P system
Find information about the placement rules and slot priorities for the Peripheral Component Interconnect Express (PCIe) adapters that are supported for the IBM® Power® System LC921 (9006-12P).
PCIe slot descriptions
The 9006-12P system provides PCIe generation 4 slots. Full-length, half-length, or short (low-profile) adapters can be installed. Figure 1 shows the rear view of the system with the PCIe adapter slots. Table 1 lists the PCIe adapter slot locations and details for the 9006-12P system.
| Slot location | CPU Connection | Description | Adapter size | Coherent Accelerator Processor Interface (CAPI) |
|---|---|---|---|---|
| 1 (UIO Slot1) | CPU1-PEC0 | PCIe4 x8 | Half-height, half-length, internal | Yes |
| 2 (WIO Slot1) | CPU2-PEC0 | PCIe4 x16 | Double-wide, full-height, full-length | Yes |
| 3 (WIO Slot2) | CPU2-PEC2 | PCIe4 x16 | Full-height, full-length | Yes |
| 4 (WIO-R Slot) | CPU2-PEC1 | PCIe4 x8 | Half-height, half-length | No |
PCIe adapter placement rules
Use this information to select slots for installing PCIe adapters in the 9006-12P system. Table 2 provides information about the adapters, the
slot priorities in the system they are supported on, and the maximum number of adapters that can be
installed in the supported system. You can click the link that appears in the feature code column
for more technical information specific to the PCIe
adapter.
