PEP 2.0 - Ability to disable/offline resources(CPU/Memory)

Currently PEP 2.0 activates all installed resources. This creates lot of issues with our capacity management, performance monitoring and high availability. Please have an option to disable specific number of CPU and memory on the frame.

    Can you please elaborate on the proposal. I am not sure about shared processor pool level limit. Any partition level limits cant meet the requirement. Again, what we want is to avoid the situation where we use all capacity in a host group and no room for planned or unplanned maintenance. we can do webex if needed or call me directly.

    Hi Santhosh,

    Partition level or shared processor pool level limits can still be used to control the utilization of the partition such that the overall utilization doesn't go beyond the desired limit. can you please let us know if there are any challenges with that approach?

    Thanks.

    Yes, the requirement is to have an option to enable/disable x% of the CPU/Memory so that we can control the total utilization of individual frame below 80/90% in the event of workloads moving from other frames while hardware maintenance or capacity add or organic growth

    Hi Santhosh,

    PEP2.0 concept is to have all resources activate on the system , but usage is tracked and metered based on utilization. In this specific use case, can you let us know if there would be use case to enable the disabled CPU/memory later ? i.e. like PEP1.0, would the use case be enable the activated capacity at a later point of time?

    Thanks.
