Planning for AME

Active Memory Expansion (AME) improves memory usage for virtual machines. It expands the physical memory that is assigned to a virtual machine by allowing the operating system to effectively use more memory than it was assigned. The hypervisor compresses the least used memory pages to achieve the expansion. The increase in available memory is called the expansion factor. To enable AME, use an advanced compute template.

AME Requirements

Your system must meet these requirements to use AME with PowerVC:
  • PowerVC version 2.1.1
  • AIX® Version 6.1, or later
  • POWER7®, or later
