PCIe slot descriptions for the 8247-42L

The 8247-42L system provides PCIe generation 3 slots. Table 1 provides information about the PCIe slots in the 8247-42L system 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 EJ08) 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. ³One PCIe gen3 x16 graphics processing unit (GPU) adapter (FC EC47 or EC4B) is preinstalled in slot 5 (P1-C6). The GPU adapter requires two slot space for accommodating the air baffle. ⁴The I/O Adapter Enlarged Capacity assignment order value is 5 for one processor or 10 for two processors. ⁵The I/O Adapter Enlarged Capacity assignment order value is 6 for one processor or 8 for two processors. 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. Regular full-height adapters can be installed only in the full-height, full-length slots 2, 4, 5, and 6. The full-height, half-length or short (low-profile) adapters can be installed in slots 1, 3, 7, 8, 10, and 11. 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 8247-42L 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.

IBM Manufacturing requires that slot P1-C10 hold a local area network (LAN) adapter to install and test the server. One LAN feature code (FC) 5899, EN0W, EL55, or EN0S should be selected for this purpose. IBM ships the LAN adapter in the P1-C10 slot. If needed, the client can move the LAN adapter to a different slot allowing other PCIe adapters to be placed in P1-C10. The following tables assume that the LAN adapter remains in the P1-C10 slot.
The PCIe3 cable adapter (FC EJ08) is supported in slots P1-C3, P1-C6, P1-C5, and P1-C7 on 8247-42L systems that do not have a GPU adapter installed.
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. For these full-height, full-length slots, first priority must be given to GPU adapters followed by PCIe x16 adapters, CAPI adapters, Single Root IO Virtualization (SR-IOV) capable adapters, FC EJ12 (FPGA Accelerator), high-performance adapters, ending with all other supported adapters.
CAPI accelerator adapters are supported in slots P1-C6, P1-C7, P1-C3, and P1-C5.
Slots P1-C2 and P1-C4 are x8 slots with busses direct from the Processor Modules and can be used to install high-performance PCIe adapters.
Slots P1-C2, P1-C3, P1-C4, P1-C5, P1-C6, and P1-C7 are slots with busses direct from the Processor Modules and can be used to install high-performance PCIe adapters that support the Single Root IO Virtualization (SR-IOV) function.
PCIe internal slots P1-C14 and P1-C15 are used to install the SAS RAID adapter FC EJ0S and the internal SAS RAID adapter (CCIN 57D8).
When the internal SAS RAID adapter (CCIN 57D8) is installed in an expanded function system and if FC EJ0Z is installed in the PCIe slot P1-C11, slot P1-C11 is not available for installing any other PCIe adapter.

Verify whether the adapter is supported for your system. For details about the supported adapters, see PCI adapter information by feature type for the 8247-42L, 8286-41A, or 8286-42A.
