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.
