And the days of IPL'ing frequently are long gone for us.  We seldom  IPL
and then it only for an hour or so.  TSM just takes right up where it left
off.

Not exactly. We are currently running TSM 4.2.1.9 on a 9672-R44 running
OS/390 2.10 and we have been doing an evaluation on moving TSM from OS/390
on to AIX. While the cost of the AIX hardware is relatively cheap we still
need to incur DASD costs in the form of SAN and Tape costs, not to mention
the need to develop cron jobs on AIX to handle tape processing , on OS/390
you do not have to define volumes, drives or the library to TSM. Also we
found that the licensing costs of TSM itself on AIX were actually higher
than the mainframe costs. Granted we are tied into tape media (STK 9840)
and our management is not looking to replace that media but even if we did
the cost is still slightly higher for us on AIX.

Bad... total cost of ownership is too high.  Too many fingers in the pie
(tape group, dasd group, TCPIP group, operations etc...  When you begin to
figure out total cost of ownership, you have to add
all of these support teams into the equation, not to mention the internal
charge (funny money) for MIPS usage on the mainframe that you'll incur. TSM
will also be at the mercy of the mainframe IPL
schedule as well, which typically is on Saturday night into Sunday morning
(a window that you really want open for your large archives or db backups)

If you're on any other platform, your costs should drop significantly.
e.g.  If you have a P690, you have 1 SA managing that server.  You don't
need nearly the staff that you'd require for a
mainframe solution.  How often does an AIX or Sun machine have to be taken
down for maintenance? (not often).  And finally, a P690's I/O is comparable
to a mainframes.

If you get the budget, go with a big Unix system.  Run screaming from the
mainframe solution.  You'll save a lot of headaches and meetings.  Just my
opinion.

Regards, Joe

We do. It works fine for us, but we are migrating off to Unix for D.R.
reasons.
