The 5148-21L, 5148-22L, 8247-21L, 8247-22L, 8284-21A, or 8284-22A system provides PCIe generation 3 slots. Table 1 provides information about the PCIe slots in the 8247-21L system that has a single POWER8® processor module, the 8247-22L system that has two POWER8 processor modules, and the 8284-22A that offers both a single POWER8 processor module or two POWER8 processor modules. The PCIe slots are enabled to support the PCIe3 cable adapter (FC EJ05) that is used to attach the EMX0 PCIe Gen3 I/O expansion drawer.

¹Slot is a direct slot from the Processor Module and is a high-performance slot. The connectors in these slots are differently colored than the slots from the PCIe3 switches. ²Slot connected by the PCIe3 switches. ³Slot is not available to install other adapters in the expanded function system backplane. ⁴The I/O Adapter Enlarged Capacity assignment order value is 6 for one processor or 8 for two processors. ⁵Assigned PCIe slot order when the I/O Adapter Enlarged Capacity option is enabled. For example, if the option was enabled with a value of 5 on a two processor system, five slots (P1-C6, P1-C7, P1-C10, P1-C12, and P1-C2) are enabled with the I/O enlarged capacity. If the option was enabled with a value of 7 on a two processor system, then six slots (P1-C6, P1-C7, P1-C10, P1-C12, P1-C2, and P1-C11) are enabled with the I/O enlarged capacity, and so on. Note: Enabling the I/O Adapter Enlarged Capacity option will only affect Linux partitions. If your system does not have Linux partitions, the I/O Adapter Enlarged Capacity setting should be disabled. ⁶For platforms with less than 64GB of total system memory, SR-IOV should not be configured in these slots as performance may be severely impacted. All slots are PCIe generation 3 slots. 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 the x8 slots are 8 GBps in simplex mode and 16 GBps in duplex mode. All slots support enhanced error handling (EEH). All PCIe slots are hot swappable and support concurrent maintenance.

PCIe adapters placement rules

Use this information while selecting slots for installing PCIe adapters in the 5148-21L, 5148-22L, 8247-21L, 8247-22L, 8284-21A, or 8284-22A system. Use Table 4 to identify slot placement priorities in the system and the maximum number of adapters that can be installed in the system

The slot P1-C10 must be used to install the local area network (LAN) adapter feature codes (FCs) EN0T, EN0V, or EN0X. Any other PCIe adapter feature is not supported in this slot.
The PCIe3 cable adapter (FC EJ05) is supported in slots P1-C3, P1-C6, and P1-C7.
Note: This is a double-wide adapter that requires two adjacent slots.
CAPI accelerator adapters are supported in slots P1-C6, P1-C7, P1-C3, and P1-C5.
Slots P1-C3, P1-C5, P1-C6, and P1-C7 are x16 slots with busses direct from the Processor Modules and can be used to install high-performance PCIe adapters. The adapter priority for these slots is for CAPI accelerator adapters (for example, EJ16), PCI accelerator adapters (for example, EJ13), and then for the high-performance adapters, followed by any other adapter.
Slots P1-C2 is an x8 slot with bus direct from the Processor Modules and can be used to install high-performance PCIe adapters. The adapter priority for this slot is for the high-performance adapters followed by any other adapter.
Slots P1-C2, P1-C3, P1-C5, P1-C6, and P1-C7 are slots with busses direct from the Processor Modules and are recommended for high-performance PCIe adapters that support the Single Root IO Virtualization (SR-IOV) function.
FCs 5901, 5278, 5284, and 5287 are not supported in the slots P1-C8, P1-C9, P1-C10, P1-C11, and P1-C12.
PCIe internal slots P1-C14 and P1-C15 are used to install the SAS RAID adapter FC EJ0V or EL3V and the high-performance internal SAS RAID adapter (CCIN 57D8).
When the high-performance internal SAS RAID adapter (CCIN 57D8) is installed, the FC EJ0Z is installed in PCIe slot P1-C9 and slot P1-C9 is not available for installing any other PCIe adapter. Slot P1-C9 is used to install the two external SAS ports.

Verify whether the adapter is supported for your system. For details about the supported adapters, see PCIe adapter information by feature types for the 5148-21L, 5148-22L, 8247-21L, 8247-22L, 8284-21A, or 8284-22A.
