PCIe adapter placement rules and slot priorities for the 8001-22C or
8005-22N system
Find information about the placement rules and slot priorities for the Peripheral Component Interconnect
Express (PCIe) adapters that are supported for the IBM Power System S822LC for Big Data (8001-22C) or
the IBM CS822 (8005-22N).
PCIe slot descriptions
The 8001-22C or 8005-22N system provides PCIe generation 3 slots. Full-length, half-length or short
(low-profile) adapters can be installed. Figure 23 shows the rear view of the system with the PCIe adapter
slots. Table 6 lists the PCIe adapter slot locations and details for the 8001-22C or 8005-22N system.
Important: The only two adapters that are currently supported on the 8005-22N are FC EKFH and
AOC-S3008L-L8e-P.
