Runs with IBM iYes ... Memory is OS independent; the S1122 IBM i rules come from the processor feature, not the memory.

Each feature delivers two DDIMMs. S1122 needs 32 GB minimum with one processor module (pairs) and 64 GB with two (quads). Midland lists the same feature for the L1122 (9856-22H) and L1124 (9856-42H).

Before you order EM54

Adding memory can give a busy Power 11 more room without replacing the server. Match the new modules to the size and type already installed, and check how many memory slots your model has free before you order.
