C.15 AS/400 Advanced Servers
For AS/400 Advanced Servers the knee of the curve is about 1/3 the maximum interactive CPW value.
For releases prior to V4R1 the model 150 was constrained due to the memory capacity. With the larger
capacity for V4R1, memory is no longer the limiting resource. In V4R1, the limit of 4 DASD devices is
the constraining resource. For workloads that do not perform as many disk operations or don't require as
much memory, the unconstrained CPW value may be more representative of the performance capabilities.
An unconstrained CPW rating means the processor is the first constrained resource.
