Even by using the soft capping option, the use of the partition can reach up to its maximum share based on the number of logical processors and weights in the image profile. Only the 4-hour rolling average utilization is tracked, which allows utilization peaks above the defined capacity value. 

Some pricing metrics apply to stand-alone Z servers. Others apply to the aggregation of multiple Z server workloads within the same Parallel Sysplex. 

For more information about WLC and details about how to combine logical partition utilization, see z/OS Planning for Sub-Capacity Pricing, SA23-2301. 

## Key MLC Metrics and Offerings 

MLC metrics include various offerings. The following metrics and pricing schemes are available. Offerings often are tied to or made available to only on certain Z servers:

One of the recent changes in software licensing for z/OS and z/VSE is Multi-Version Measurement (MVM), which replaced Single Version Charging (SVC), Migration Pricing Option (MPO), and the IPLA Migration Grace Period. 

MVM for z/OS and z/VSE removes time limits for running multiple eligible versions of a software program. Clients can run different versions of a program simultaneously for an unlimited duration during a program version upgrade. 

Clients can also choose to run multiple different versions of a program simultaneously for an unlimited duration in a production environment. MVM allows clients to selectively deploy new software versions, which provides more flexible control over their program upgrade cycles.
