Spyre Accelerator for Power: IBM i Shop Prerequisites

Spyre is a PCIe-attached inference accelerator for supported Power 11 configurations, not a native IBM i feature. Check the expansion drawer, Linux runtime, Red Hat stack, and resource minimums.

IBM Spyre Accelerator for Power is a PCIe-attached inference card offered for supported Power 11 systems. IBM documents an ENZ0 expansion drawer and a Red Hat inference stack. For an IBM i shop, the key distinction is that the documented accelerator environment runs in a supported Linux and Red Hat setup, not natively as an IBM i feature. Your IBM i workload may supply data, but it is not itself the Spyre runtime.

Requirements to check before a quote

Supported systemIBM lists Power 11 systems and specific machine types for supported card counts. Do not infer that every Power 11 model, including S1112, accepts this configuration.

Expansion drawerIBM documents the ENZ0 PCIe4 expansion drawer for the Power Spyre configuration.

Operating environmentIBM lists RHEL 9.6, 9.8, and 10.2 with Red Hat AI Inference Server or Red Hat OpenShift AI and container runtime requirements. Confirm the current support matrix.

Resource floorIBM's published software-resource minimum is 512 GB memory, 10 CPU cores, and 600 GB storage. Model size and concurrency can raise those needs.

When Spyre is not the next step

If the first use case is IBM Bob for RPG code assistance, an external watsonx application, or a small local model that a supported Power CPU runtime can handle, the Spyre drawer may not answer the actual need. Pilot the workload, confirm where it runs, and size the system from measured throughput. On-chip MMA and Spyre solve different capacity problems.
