Power Enterprise Pools 2.0 - Metered Usage Enhancements

Power Enterprise Pools 2.0 resource sharing and metered usage is a step-change for Power Systems private cloud adoption. To improve it further, more granular control and visibility is required at the host partition level.

I'd like to request an enhancement to PEP 2.0 to enable control of base and metered capacity at the partition level. What is required is configuration options to enable a:

- Partition to only access base capacity
- Partition to only access metered capacity
- Partition to access both base & metered capacity (the current operating mode)

In addition to this enhancement, we need to be able to export the metered capacity per partition in credits for chargeback purposes.

    Hi David,

    Currently, the concept of EP2.0 is sharing resources across a pool of systems and all the capacity/utilization is tracked at a pool level for metering purposes. So even though there is base capacity per system, its aggregated across the pool. So to restrict usage of base vs metered at a specific partition level would be a new model for Enterprise Pools. We will evaluate the request to see the possibilities.

    Thanks.

    Thanks.

    Thanks for the feedback. I can see how these API's would be useful to automate & externalise the usage data. The issue however remains in that capacity is calculated at the Pool level, not at the partition level. With scale-up Power Systems we have the capacity to run 100's of partitions on a single physical system, we need usage data at the partition level.

    The reporting was one part of this enhancement, the more important component of this RFE is to provide greater controls for base and metered capacity at the partition level. What is required is configuration options to enable a:

    - Partition to only access base capacity
    - Partition to only access metered capacity
    - Partition to access both base & metered capacity (the current operating mode)

    Will this require a fundamental change in the way EP 2.0 is currently designed?

    Hi David,

    For chargeback purposes, we have currently provided API's that can be used for retrieving utilization information for systems and lpars. You can add tags and group them based on the categories needed. Granular partition level control can still be done existing partition level settings as needed, but the base/metered capacity is calculated at a pool level currently. Please see if the below API's would help you for charge back purposes

    Having the functionality as identified in the 3 example use cases would be great for our business

    These enhancements would align the PEP 2.0 Metered Usage to the real world use cases of PEP. We (as a BP) have the requirement from users to be able to provide chargeback to environments/projects that consume Credits.
