IBM Virtualization Best Practice Guide - Version 4 updates
Optimizing Performance

The IBM Power System Performance team recently published an update to the IBM POWER Virtualization Best Practices Guide . This guide provides information, examples and in-depth information about the following topics:

  • Virtual Processor - Advice on choosing the right entitlement and number of virtual processors for VMs.
  • Information about AIX processor folding and how this affects performance
  • AIX tuning information related to Simultaneous Multi-Threading (SMT)
  • Hardware Page Table tuning information
  • Resource management by the PowerVM Hypervisor including:
    • VM resource assignment ordering
    • Overview of how the PowerVM Hypersior makes resource assignment decisions
    • How to display the resources assigned to a VM
    • How to optimize resource assignments
    • **NEW** Partition mobility and DPO considerations for Linux
    • User controls over resource assignments
    • Resource assignment considerations for failover, DR, Partition Mobility, server evacuation
    • How licensing affects resource assignments
  • Energy Scale™
  • Processor Compatibility Modes

Many of the ideas for the chapters came from customer requesting information about a specific topic. This lead to the development of the IBM Virtualization Best Practice Guide as a resource for POWER customers.  A new update is planned for later this year based on feedback from our customers.
