Active Memory Expansion (AME)
Improve use of physical memory
If you need to free up physical memory on a server, AME can be used to reduce the memory assigned to an LPAR.
Active Memory Expansion:
- Compresses the least used memory pages in conjunction with the hypervisor
- Exploits on-chip compression acceleration in POWER7+ and POWER8 systems
- Estimates the benefit for a particular workload using the amepat (AME Planning and Advisory Tool)
