AIX (Advanced Interactive eXecutive) is a series of proprietary Unix operating systems developed and sold by IBM.
Performance Optimization With Enhanced RISC (POWER) version 7 enables a unique performance advantage for AIX OS.
POWER7 features new capabilities using multiple cores and multiple CPU threads, creating a pool of virtual CPUs.
AIX 7 includes a new built-in clustering capability called Cluster Aware
AIX POWER7 systems include the Active Memory Expansion feature.
