PCIe adapter placement rules and slot priorities for the EMX0 PCIe Gen3 I/O expansion drawer
Find information about the placement rules and slot priorities for the Peripheral Component Interconnect (PCI) Express (PCIe) adapters that are supported for the EMX0 PCIe Gen3 I/O expansion drawer (EMX0 PCIe3 expansion drawer).
PCIe slot descriptions for the EMX0 PCIe3 expansion drawer
The number of PCIe slots that are provided in the EMX0 PCIe3 expansion drawer depends on the I/O module configuration of the EMX0 PCIe3 expansion drawer. Your configuration might have one or two PCIe3 6-slot fanout modules (FC EMXF or ELMF) installed in the rear of the EMX0 PCIe3 expansion drawer. Each PCIe3 6-slot fanout module provides six full-length, regular-height, PCIe generation 3 slots. The PCIe3 slots are compatible with generation 2 or generation 1 PCIe adapters. The PCIe slots use generation 3, single-wide, blind-swap cassettes.
The I/O module in the EMX0 PCIe3 expansion drawer is connected to the system with an expansion drawer cable pair. Each cable pair must be the same length and are attached to the T1 and T2 ports in the I/O module and to the corresponding ports in the PCIe3 cable adapter in the system.
Figure 1 shows the rear view of the EMX0 PCIe3 expansion drawer with the location codes for the PCIe adapter slots in the PCIe3 6-slot fanout module.
Table 1 lists the PCIe adapter slot
locations and details for the EMX0 PCIe3 expansion drawer.

codes
Note:
- The left I/O module bay (as viewed from the rear) is configured with the first PCIe3 6-slot fanout module slot location codes P1-C1 through P1-C6.
- The right I/O module bay (as viewed from the rear) is configured with the second PCIe3 6-slot fanout module slot location codes P2-C1 through P2-C6.

| 1The SR-IOV capability varies in slots P1-C4 and P2-C4 based on the amount of system memory. If the EMX0 PCIe3 expansion drawer is connected to a system with a total amount of physical memory greater than or equal to 128 GB, slots P1-C4 and P2-C4 are SR-IOV capable. 2The Dynamic direct memory access (DMA) window capability varies based on the amount of system memory. If the EMX0 PCIe3 expansion drawer is connected to a system with a total amount of physical memory greater than or equal to 64 GB, the slot is Dynamic direct memory access (DMA) window capable. If the total amount of physical memory is less than 64 GB, the slot is not Dynamic direct memory access (DMA) window capable. 3Slots P1-C1 and P2-C1 inherit the I/O Adapter Enlarged Capacity attribute from the slot in the system that connects to the EMX0 PCIe3 expansion drawer. |

Notes:
- All slots are PCIe generation 3 slots.
- All slots support full-length, regular-height adapters or short form-factor with a regular-height tailstock in single-wide, generation 3, blind-swap cassettes.
- Slots C1 and C4 in each PCIe3 6-slot fanout module are x16 PCIe3 buses and slots C2, C3, C5, and C6 are x8 PCIe buses.
- 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 EMX0 PCIe3 expansion drawer attached to the system. Use Table 2 to identify slot placement priorities and the
maximum number of adapters that can be installed in the EMX0 PCIe3 expansion drawer based on the operating system.
Note: You can click the link
that appears in the feature code column for more technical information specific to the PCIe adapter.
- If the EMX0 PCIe3 expansion drawer is configured with two PCIe3 6-slot fanout modules, distribute the PCIe adapters across both I/O modules whenever possible.
- If FC EC46 is driving the internal DVD, it must be installed in the IO expansion
drawer that is closest to the system. The system and IO expansion drawer must be in the same
rack.Note: If slot P1-C2 of the first node contains a controller adapter (CC), it must be the first option to consider for wiring the module (FanOut or DirectSlot) with the USB adapter driving the internal DVD. If it is a FanOut module, install FC EC46 in slot Px-C3 of the FanOut module.
- Do not attempt to install x16 adapters in x8 slots. Doing so can damage the x16 connectors in the EMX0 PCIe3 expansion drawer.
Verify whether the adapter is supported for your system. For details about PCIe adapter placement rules and slot priorities, see PCIe adapter placement.
