IBM Power Ideas Portal


This portal is to open public enhancement requests against IBM Power Systems products, including IBM i. To view all of your ideas submitted to IBM, create and manage groups of Ideas, or create an idea explicitly set to be either visible by all (public) or visible only to you and IBM (private), use the IBM Unified Ideas Portal (https://ideas.ibm.com).


Shape the future of IBM!

We invite you to shape the future of IBM, including product roadmaps, by submitting ideas that matter to you the most. Here's how it works:

Search existing ideas

Start by searching and reviewing ideas and requests to enhance a product or service. Take a look at ideas others have posted, and add a comment, vote, or subscribe to updates on them if they matter to you. If you can't find what you are looking for,

Post your ideas
  1. Post an idea.

  2. Get feedback from the IBM team and other customers to refine your idea.

  3. Follow the idea through the IBM Ideas process.

Allow VMRM/DR to scale CPU UP (>100%)

Currently VMRM/DR allows the CPU to be scaled down when an LPAR moves to the DR site.

However, when we're moving a correctly-sized LPAR from a POWER9 to a POWER8, this severly reduces the performance, even when using 100% due to the difference in performance between the two CPU generations. This will also apply to POWER10->POWER9/8.

We want VMRM/DR to allow a CPU factor > 100% so that the per-CPU performance loss can be compensated by an increase in entitlement/vCPUs.

Ideally, two other options could be added: rPerf and SAPs, so that the CPU resources can keep either the rPerf or the # of SAPs.
