PCIe Adapters for Power 11
Networking, SAN, and tape connectivity adapters across direct-chassis PCIe Gen4 slots, the I/O layer common to every current Power 11 model.
Power 11's direct chassis I/O runs on non-hot-plug PCIe Gen4 slots, with slot count and mix (x16 vs x8) varying by model. The entry S1112 carries 4 direct slots (2x x16, 2x x8); larger scale-out and enterprise models carry the same slot family with additional capacity added through Gen4 I/O expansion drawers rather than a different PCIe generation.
Confirm adapter-level compatibility (specific Ethernet, Fibre Channel, or tape HBA feature codes) against your target model's current IBM sales manual before finalizing a configuration -- adapter support varies by firmware level and can change between announce dates.

Frequently Asked
What PCIe generation does IBM Power 11 use?
Current Power 11 models use direct-chassis PCIe Gen4 slots. The entry S1112 carries 4 non-hot-plug Gen4 slots (2x x16, 2x x8); larger models add capacity through Gen4 I/O expansion drawers rather than a different slot generation. Confirm exact slot count and mix against your target model's spec page before ordering adapters.
Which IBM FlashCore Module generation should I use with Power 11?
Power 11 does not dictate the FlashCore Module generation directly, since the module lives in the attached FlashSystem array, not the Power 11 chassis. The generation (FCM1 through FCM4) and capacity (4.8 TB to 38.4 TB) are set by the FlashSystem model and existing pool configuration. Match the exact part number and feature code to that FlashSystem model, then confirm the Power 11 side has a supported Fibre Channel adapter for the attachment.
