Power 9

S914 vs S1112

How Power 9 S914 owners should think about the Power 11 S1112 and S1122 replacement decision.

The Power 9 S914 is a common entry IBM i server, but IBM replacement guidance for the original 9009-41A points to the S1122 class rather than assuming a like-for-like S1112 swap. The S1112 can still fit smaller environments, but the right comparison depends on IBM i memory, core, and partition requirements.

Use S1112 for compact current-generation needs. Use S1122 when the S914 environment grew beyond small IBM i limits or needs more consolidation headroom.
