Bizarre it is, at least to someone who is used to a modern environment. I once hat a gig setting up a open source softare stack on AIX, it was very painful to do. AIX admins aren't really helpful either because their knowledge is really domain specific and everything they usually run is well documented / supported by IBM. For anything open source related on AIX, http://www.perzl.org/aix/ http://www.perzl.org/aix/ is a lifesaver. But, the hardware just scales brutally. You can add/remove LUNs/CPUs/RAM from LPARs without interrupting operations. The Powers hosting the machines I worked on were basically bought, installed and switched on and are now up and running until they are decommissioned years later.
