What are AIX systems?

AIX is in fact a UNIX compliant operating system, from IBM. It was first released at the very back end of the 1980's, however was not really widely adopted until the early 90's. The version 7 beta has just been released (July 2010). It is currently the number 1 UNIX operating system on the market.

AIX runs exclusively on IBM's POWER systems, which are by far and away the most powerful and robust UNIX boxes. The POWER platform has been around for generations now, and builds on IBM's mainframe capabilities providing outright performance and reliability (IBM's POWER6 5GHz chips were the fastest available on the market, until recently beaten by POWER7. They significantly outperform Nehalem and Westmere chips...).

I suggest you check out www.ibm.com and Google for more information.
