Software considerations
Software Parallel Sysplex® License Charge (PSLC) customers are billed at the million service unit (MSU) level represented by the combined permanent and temporary capacity. All PSLC products are billed at the peak MSUs enabled during the month, regardless of usage.
Customers with Workload License Charge (WLC) licenses are billed by product, at the highest four-hour rolling average for the month. In this instance, temporary capacity does not necessarily increase your software billing until that capacity is allocated to logical partitions and actually consumed.
For customers with IPLA, there is a daily charge for additional capacity above the current capacity purchased.
There may be additional fees for non-IBM® software. In addition, some non-IBM software packages may require new license keys in order to take advantage of the additional capacity. Check with your software vendor for details.
See your IBM sales representative for further information.
