Before the results a few observations:

Questions: How many of these features are originally in the AT&T UNIX 5.2 and 5.3 from which AIX was developed?

Answer: None of them as they are all IBM improvements.

Question: Which are long-term AIX features (i.e excluding feature introduced with AIX 6 and 7)?

Answer: Roughly half of them and many from AIX 3 which was the first to run on POWER processors.

And the New Features:

• Very interesting results.
• I am proud that nmon is in the top three but that might have been a side effect of me running the Survey - we may never know.
• Four in the top eight have been in AIX for decades (smitty, NIM, mksysb and LVM)
• The other four have been in AIX for over 10 years! (PowerVM, nmon, DLPAR and LPM).

Comments:

Clearly, it is hard for new features to compete with the old established favourites but I think these are pretty high rankings for the new features.

Next time!! we might ask what are the favourites out of the big new features introduced in the past 5 or 10 years. I would guess PowerVC, Enterprise Pools and Live Kernel Update would be the winners but also AIX Flash Cache and Shared Storage Pools would feature strongly too.

Please help in raising AIX’s profile via Social Media and say why you like it today.

Thanks to everyone that voted.

For the record this is the vote percentages:
