PCIe slot descriptions for the 8286-41A and 8286-42A

The 8286-41A and 8286-42A system provides PCIe generation 3 slots. Table 1 provides information about the PCIe slots in the 8286-41A system that has a single POWER8® processor module and the 8286-42A system which 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. ³Assigned 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 6 on a two processor system, then six slots (P1-C6, P1-C7, P1-C10, P1-C12, P1-C2, and P1-C4) 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. 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 8286-41A or 8286-42A 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 the slot P1-C10 to hold a local area network adapter (LAN) adapter to install and test the server. One LAN feature code (5899, EN0H, EN0K, EN0M, EN0S, EN0U, EN0W, EN15, or EN17 for systems running AIX® or Linux; 5899, EN15, or EN17 for systems running IBM® i) should be selected for this purpose. IBM will ship the LAN adapter in the P1-C10 slot. The client can move this LAN adapter to a different slot and can use P1-C10 for different adapters if appropriate. The following tables assume the LAN adapter remains in the P1-C10 slot.
The PCIe3 cable adapter (FC EJ08) is supported in slots P1-C3 (Slot 2), P1-C6 (Slot 5), P1-C5 (Slot 4), and P1-C7 (Slot 6).
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 the FC EJ12 (FPGA Accelerator), then for the high-performance adapters, followed by any other adapter.
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. The adapter priority for these slots is for the high-performance adapters followed by any other adapter.
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 (SRIOV) function.
FCs 5287 and 5901 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 EJ0S and the high-performance internal SAS RAID adapter (CCIN 57D8).
When the internal SAS RAID adapter (CCIN 57D8) is installed in an expanded function system and if the 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.

The 8286-42A system can have one or two system processor modules. The PCIe slot configuration in the 8286-42A system with a single processor module is the same as in the 8286-41A system.

¹The PCIe slot priorities are for the 8286-42A system with two processor modules, while the slot priorities for the 8286-42A system with a single processor module is the same as for the 8286-41A system. ²The slot is not available to install other adapters in the expanded function system with the FC EJ0Z installed in this slot. ³The adapters FC 5901 and 5287 are not supported in slots 7, 8, 9, 10, and 11. ⁴ The adapters FC EJ16, EJ17, and EJ18 are not compatible with the adapters FC EJ12 and EJ13. The FC EJ12 and EJ13 adapters are for gzip compression offload, and the FC EJ16, EJ17 and EJ18 are for direct-attach fibre channel flash acceleration. ⁵The PCIe Cryptographic Coprocessor must not have any other adapter installed in a slot that is adjacent to it for thermal and cooling reasons. Installing an adapter adjacent to the PCIe Cryptographic Coprocessor invalidates the product warranty.The PCIe Cryptographic Coprocessor can be installed in an end slot, which requires a total of two slots that are adjacent. Otherwise, a total of three slots that are adjacent is required.
