Glenn,
Mr. Zeitler also said "And I think Frank Soltis and the people in Rochester
broke the code on this some time ago." I hate to put words into Mr.
Zeitler's mouth. But I believe he is referring to when the AS/400 first
came out in 1988. They built in the capability to run S/38 style programs
and AS/400 programs simultaneously. (That may not seem like much, but a
"CLP38" program refers to objects by "objectname.library" where the 400
"CLP" uses "library/objectname".) So the 400 has these two "personalities".
Plus it can also be run in S/36 mode by setting a system value.
And then a few years ago they added PASE. I have no idea how that's
implemented; but it's pretty amazing stuff. No matter how it's done, from
my point of view I see the iSeries having 4 distinct OS personalities. I
don't know about S/36 mode, but I'm pretty sure the rest can be run
simultaneously.
That seems, to me anyway, like the SLIC is already something like a
"hypervisor". I don't know if that's what Mr. Zeitler meant, though.
I never heard of PLIC. If that's Partition LIC that runs LPAR, then it sure
does give the iSeries even more capabilities to run different OS like Linux,
etc.

When you reference SLIC,do You mean PLIC for LPAR on AS400 that supports
hypervisor ?

FWIW. Here is an interview with Mr. Zeitler:
http://www.sellingeserver.com/artarchive/index.cfm?fuseaction=viewarticle&Co
ntentID=355
To oversimplify, as head of the Server Group, he ultimately determines the
fate of the iSeries. About half-way into the interview, he discusses
running multiple OS and the emergence of a "hypervisor control layer, not
unlike the slick layer on the AS/400".

I do what I where I can, As Bob Tipton did in his way. As I said before,
I can't argue with your logic John, Nor can I argue with your conclusions
from a pragmatist's perspective. I understand them, and appreciate them.
And Yes, Corporate IBM (not Rochester) does indeed seem to want a simple
world of Linux and Win2000. There is certainly more money in service
selling them(For Global Services) than selling an iSeries.
I think IBM is hearing your points too(at least part of IBM). The sad part
is that we DON'T know IBM's 5 or 10 year plan. We don't know if eServer is
phaseI of the uServer machine. The PowerPC seems to be doing well. At
this point it seems to be doing better than Intel's attempts at 64bits (and
everyone else's). I know, that's PowerPC not OS/400.
It may not be the future, but a possible future, The PowerPC can run
Linux, OS/400, AIX, and it could run Win(if MS wanted to do the port and
hedge it's bet against Intel's follies and Linux's rise).
I believe that it could be technologically possible to even run MVS on the
S-Star PowerPC.
Wouldn't it be something if OS/400 was the controlling partition on a
uServer that runs all of them?
Well....taking my rose colored idealist's glasses off, Yes, I will morn
the day if your conclusions come into reality. and Yes, I will fight the
fight till then(my fingers are cold but not quite dead yet :-) ).
However make no mistake that I am listening to you John, and appreciate
that you saying it.
Respectfully
John Carr
