IBM i Modernization Software

Can IBM i use all 10 cores on a Power S1112 configuration?

No. IBM's S1112 limitations page says IBM i logical partitions on this platform are capped at a cumulative maximum of four cores. Midland's article is useful here because it pushes back on the common misread that a larger core count automatically means IBM i itself gets all of those cores.

The extra headroom matters for Linux, AIX, or VIOS side workloads, not because one IBM i partition suddenly escapes the documented IBM i boundary. Buyers should separate total server resources from the portion IBM i can actually consume.
