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.

Concurrent replacement for the FSP

The FSP (Flexible Service Processor) cannot be changed in Concurrent mode.

The E870C and E880C Systems have a dual FSP configuration, the failover of a FSP System does not create an outage.
But the replacement of the failed FSP must be done after of full stop of the VM - VIOS and System.

The replacement duration takes 2 hours at least only for the FSP replacement and synchronization.

The total time for such an operation takes nearby one day if you consider also the requested time to shutdown and restart all the VIOS and VM.

Changing the FSP in concurrent mode would improve the availability of the Power Systems.

Moving the hosted VM to another Power System with LPM is not possible in any situation because you must own a second Power server.

    We continue to evaluate adding a capability at each new generation of the high end Enterprise systems. In fact, several hardware changes went in to the POWER9 E980 design to enable this function. However, due to the severe complexity of the code to implement this function we were not able to provide this capability for the POWER9 systems. We will continue to evaluate this for future versions of the POWER high end servers.

    For availability reasons the concurrent replacement of a FSP would be a very useful feature. This can dramatically reduce and eliminate the downtime of a E870C, E880C server. This feature should be also implemented for POWER9 servers.
