The minimum requirement for software licensing is the appropriate number of license entitlements for one processor core.” Also: “The minimum requirement for software licensing is the appropriate number of license entitlements for one whole processor core.” Fractional PowerVM partitions: “we aggregate fractional processor cores, apply shared pool capping rules, and round up at the server level to the next whole processor core.” Not an invented floor.
