Software Tier
IBM's IBM i software pricing tier (P05, P10, P20, P30) tied to a processor feature's performance level, determining IBM i license and subscription cost.
Higher software tiers generally correspond to higher-performance processor feature codes. A given Power11 model can span more than one tier depending on the processor option installed; check the specific feature code before pricing IBM i software.
