I believe the z/ versions are registered trade marked
they have an "R" by the name
z/VM®

Re: ACM award - they deserve it....
Are any of the IBM OS,s trade marked?

Some of this vast proliferation of servers was indeed (in the case of the
vaguely cluey users) about separation of control as Dave notes below. In
my experience, though, far more often it was because the administration
of the company finances found it so much easier to do a case by case
justification, with no view whatsoever of any bigger picture. ( share a
server farm? - you must be joking... it's my bonus here we are talking
about!). It is for this reason that VMware is, in my grumpy opinion,
likely to do little more than add an extra layer of complexity /overhead
top of any new hardware. The original reasoning ( or lack of it) that
caused this proliferation of squillions on servers continues unabated.
(Why do I suspect that the bean counters who run all of these companies
never liked IT folk much any way? and were therefore most relieved when
there was an alternative to the mainframe and hence those weird
non-accounting types that ran them).
I know that our z/VM Z/800 has been replaced by megawatts worth of severs,
( full rack after full rack of them!).
On the subject of IBM not trade marking VM, I wonder if it was because
once upon a time, it often meant Virtual Memory as well as Virtual
Machine?
