The cost of IBM-boxes, which you base your whole argument on, is listed
on www.ibm.com. If you had taken a few minutes to check it out you would
have found that the cost has been reduced significantly the last couple
of years.
In our TSM environment the cost and maintenance of the AIX TSM-servers
is about 5-10% of the total cost, excluding software licenses and the
man hours to keep the TSM environment running. Saving a few dollars by
using Intel/Linux-combo is totally out of the question. In our
experience the AIX-server is absolutely trouble free and it's superior
to Intel/Linux when it comes to handling I/O. In fact I would choose
Windows before Linux to avoid the device driver "kernel panic" nightmare
horror stories I so often hear about.
When you say that "the project would have to go HORRIBLY wrong before he
go to the point that it would be cheaper to stick with AIX", I have to
ask what your backup is worth in the first place. Mabybe you should
consider not backing up your systems at all and save some trouble.
"He could probably spend 6 man months working on this problem before
he'd approach the cost differential between a single Linux and AIX
server."
Sure, but not in the real world.

I've got nothing against AIX, but unless the pricing of AIX boxes has
changed significantly since the last time I looked, the project would
have to go HORRIBLY wrong before he go to the point that it would be
cheaper to stick with AIX -- especially if he's buying a bunch of them.
He could probably spend 6 man months working on this problem before he'd
approach the cost differential between a single Linux and AIX server.
(The same would be true if it were an HP or Sun server, BTW.) Then once
he solves it, he gets to experience the joys of that cost differential
over and over as he buys a bunch more Linux servers at a few thousand
dollars apiece.
We've got many clients using Linux servers all over their production
environment and I don't think it's like the picture you're trying to
paint. There can be just as many problems getting a new
AIX/Solaris/HPUX config working. Man, do I know that. I've banged my
head against many a Sun/IBM/HP/Digital keyboard.

Just out of curiosity, have you put enough work into getting this flying
that your management acknowledges that AIX would have been cheaper?
