I would have to add, that from a licensing issue, ISX wouldn't look too
attractive.  Consider...

Linux is free.  However, most important Linux applications are not free.  They
are normally charged based on a server license (per engine pricing).

So, if you bring up Websphere under ISX under MVS, you would have to buy a copy
for each S/390 engine on your system.  Of course, if you are a small MVS shop
(1 engine) no problem.  You may also need DB2 UDB for each S/390 engine (even
if you have DB2 for MVS licensed).

It may be attractive if you have a processor that doesn't support IFL engines.
But in any case, many MVS shops are very LPAR literate.  They could bring up a
LINUX LPAR for testing.  (still have the licensing problems)

>From my small MP3000 being installed now, I've mentally going though the Linux
process for the next 2-3 years.  We have a H30, single engine.  We will have
resources available for some Linux images under VM.  I can see us expanding
into an IFL engine.  But, if I continue to run Linux under the S390 processor
and not move all of it to the IFL engine, I need to double license all Linux
products (1 S/390 engine, 1 IFL engine).  Then again, the S/390 engine will
have plenty of resources available and nothing to use it on.  That is, until
the IFL engine runs out of resources.  Then we either license the Linux
applications on the S/390 engine again, or get a new box that, perhaps, has
more IFL resources available.
