You are both right, but you're missing point of IBM's SALC metric. There are still quite a few sites that cannot save money with IBM's Sub-Capacity pricing. You are currently paying ULC (Usage License Charge) or MULC (Measured Usage License Charges) probably along with PSLC (Parallel Sysplex License Charges).
For many of the sites still using PSLC they are using a combination of PSLC and MULC. This MULC applies to some key products such as DB2, CICS, IMS, and importantly MQ Series. If you use a small amount of processing power you may be able to save money with MULC. Many sites have MQ licensed this way because the one MSU each of you is using is certainly much less than paying for your installed capacity as otherwise is the basis of PSLC. Now on to Sub-Capacity Pricing with Workload License Charges. Once you start WLC you can no longer use MULC. So if you had DB2, CICS, IMS, MQ on MULC with WLC they will be charged based on the 4 hour rolling average of the LPARs where they run. Some sites only had MQ series on MULC, and they still could not save money with WLC because of the increase from they small usage of MQ in CPU time, to the 4HRA of the LPARs. And if you use MQ it is often in most of your LPARs. As you wrote $10,120 is SALC charge for 1 MSU of MQ's CPU Time. With WLC pricing for MQ V5, 123 MSUs of 4 hour rolling average in the LPARs running MQ the charge would be $10,108. So the point of SALC is to allow more sites to move to WLC and have a smaller charge for MQ than the WLC charges would lead to. This is one of those points that IBM may not tell you about.....
