- Today PEP2.0 delivers capability to allow flexible usage of system resources (core, ram, OS) across frames.
- Client evaluating PEP2.0 have expressed concern that with PEP induced flexibility, they lose control over DB/App software license usage in their environment.
- There are mechanisms for limiting core usage at VM/LPAR level (vCPU, Entitled Capacity) & at Frame level (multiple shared processor pools). But these limit leveraging PEP feature of growing workload any time on any frame.
- Client are looking for capability to ensure that in PEP2.0 facilitated flexible & floating compute environment, they can cap/limit a set of workloads to a preset limit and hence don't breach on their DB/App license compliances.
- Example: Client using multiple Oracle DBs across frames want to limit maximum core usage by all DB instances across frames.
- Requested capability for PEP is analogous to “multiple shared processor pool” feature of PowerVM.
