Features -
AIX offers full ACL support - Linux does too, but only recently, and
almost nothing supports them beyond Samba.
AIX has an audited and certified security subsystem - Linux... Hmmm.
AIX provides *VERY* robust LVM technology - Linux does too, again,
only recently. It is stable, but do I trust it as much as the
implementation on AIX? No way.
AIX supports LOTS of SCSI devices - Linux support of lots of devices
is a pain, devices are numbered based upon discovery, rather than
"learned" and remembered. That is a kludge, and one can screw oneself
pretty easily.
AIX supports thousands, even hundreds of thousands of threads, and
the schedular doesn't go "Ahhhhhhhhhhhhh!!!!" - Linux....
AIX supports SNA - Linux..... someone tried once.
ulimits on AIX actually do something - Not so much on Linux
AIX can motor through huge amounts of IP traffic, all zero copy -
Linux does pretty well, but gets stuttery in extreme conditions.
As for apps. I think it is pretty tough to think of apps that haven't
been ported: AcuCOBOL, visiFAX, SAP, etc...

Right, but if they port forward to current version of AIX, porting to
Linux from there is like falling of a log.
