PCIe adapter placement rules and slot priorities for the 9080-MHE, 9080-MME, 9119-MHE, or 9119-MME system

Find information about the placement rules and slot priorities for the Peripheral Component Interconnect (PCI) Express (PCIe) adapters that are supported for the 9080-MHE, 9080-MME, 9119-MHE, or 9119-MME system.

PCIe slot descriptions for the 9080-MHE, 9080-MME, 9119-MHE, or 9119-MME

The 9080-MHE, 9080-MME, 9119-MHE, or 9119-MME system provides eight low-profile, PCIe generation 3 slots. Standard low-profile (half-length, short-form factor) adapters are allowed in these slots. The PCIe slots are enabled to support the PCIe3 cable adapter (FC EJ07) that is used to attach the EMX0 PCIe Gen3 I/O expansion drawer. The PCIe slots support generation 3, low-profile, double-wide, blind-swap cassettes.

Figure 1 shows the rear view of the 9080-MHE, 9080-MME, 9119-MHE, or 9119-MME system with the location codes for the PCIe adapter slots.

Table 1 lists the PCIe adapter slot locations and details for the 9080-MHE, 9080-MME, 9119-MHE, or 9119-MME system.

¹Assigned PCIe slot order when the I/O Adapter Enlarged Capacity option is enabled. For example, if the option was enabled with a value of 2, two slots (P1-C1 and P1-C3) are enabled with the I/O enlarged capacity. If the option was enabled with a value of 3, then three slots (P1-C1, P1-C3, and P1-C5) 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.

Notes:

All slots are PCIe generation 3 slots.
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 9080-MHE, 9080-MME, 9119-MHE, or 9119-MME system. Use Table 2 to identify slot placement priorities in the system and the maximum number of adapters that can be installed in the system and attached expansion units.

All slots are x16 with busses direct from the Processor Modules and must be used to install high-performance PCIe adapters. The adapter priority for these slots is for the PCIe3 cable adapter (FC EJ07), SAS adapters (FC EJ0M, EJ11), followed by any other high-performance low-profile adapter.
If FC EC45 is driving the internal DVD, it must be installed in slot P1-C2 of the first system node.
All slots support Single Root IO Virtualization (SRIOV) capable adapters.

Verify whether the adapter is supported for your system. For details about the supported adapters, see PCI adapter information by feature type for the 9080-MHE, 9080-MME, 9119-MHE, or 9119-MME.
