C.11 V4R5 Additions

For the V4R5 hardware additions, the tables show each new server model characteristics and its maximum interactive CPW capacity. For previously existing hardware, the tables show for each server model the maximum interactive CPW and its corresponding CPU % and the point (the knee of the curve) where the interactive utilization begins to increasingly impact client/server performance. For the models that have multiple processors, and the knee of the curve is also given in CPU%, the percent value is the percent of all the processors (not of a single one).

CPW values may be increased as enhancements are made to the operating system (e.g. each feature of the Model 53S for V3R7 and V4R1). The server model behavior is fixed to the original CPW values.

For example, the model 53S-2157 had V3R7 CPWs of 509.9/30.7 and V4R1 CPWs 650.0/32.2. When using the 53S with V4R1, this means the knee of the curve is 2.6% CPU and the maximum interactive is 7.7% CPU, the same as it was in V3R7.

The 2xx, 8xx and SBx models are new in V4R5. See the chapter, AS/400 RISC Server Model Performance Behavior, for a description of the performance highlights of these new models.
