    Is there an Update available for "IBM Power Virtualization Best Practice Guide" covering IBM Power10 ? Current latest version is from March 2020 about POWER9, https://www.ibm.com/downloads/cas/JVGZA8RW . Thanks for your help. Kind regards Edelgard Johanna

    From a quick tour through the document, there is nothing I can see that would change this document on Virtualisation.
    The Power10 chips are:

    1. faster, with stronger threads so SMT=8 have thread 5 to 8 each doing more work, 
    2. there is MMA,
    3. faster memory and
    4. NVMe internal drives

    There are newer versions of AIX, IBMi, systems firmware, HMC and VIOS but the Virtualisation model is unchanged.

    As Nigel indicated, the virtualization is pretty much the same across different generations of Power processors but if there is a specific performance topic that anyone believes is missing, we would be happy to add that information to the Virtualization Best Practice Guide.  In addition to the Best Practice Guide we also like to write blog post in this community https://community.ibm.com/community/user/power/blogs/hariganesh-muralidharan1/2020/07/02/list-of-blogs and the performance topics always seem to receive lots of views.

    There are also Best Practice updates for Power10 to specific topics

    AIX Performance Quick Start:

    Power10 I/O:

    IBM Db2, IBM i:

    Oracle:

    For SAP, I believe there is an SAP Note on Power10 if you use/have access to that.

    Hi, 

    I am one of the authors for this publication. Unfortunately, this publication wasn't updated since we initially created it. I think there are some things which could be interested, VIOS rules, many HMC enhancements, persistent memory , etc. 

    Unfortunately, as far as I know Redbooks residencies do not have too much supporters in IBM management.
