John:
The formula we use is 4xCPU (sun 1.2 GHz or aix 1.0 GHz) is the same as one
IFL under z890 running zLinux under LPAR.
If zVM, we take away 10% power for the zVM overhead.
This is a rough estimate and gets refined upon the real circumstances.
Products licensing based on number of CPU's get penalized but we spend more
for the H/W (IBM is happy).
There are other benefits that are more important, such as saving in head
counts that I rather not get into but you can figure it out.

We don't have "gobs of money". That scenario is what is being touted by
certain managers. Personally, I don't buy it, but what do I know? They
say that Oracle is licensed by the number of processors in the box. And
that a license for z/OS on two processors (regardless of which processor
it is - z800, z890, z990, all the same cost) costs the same as a license
for Windows running on two processors. This seems silly to me, but I
cannot refute it.
Also, at one time, we did test Oracle on Linux under z/VM (back when we
had those products). The Oracle DBAs (who ran the test themselves) came
to the conclusion that a z800 single IFL and 1 Gb of memory did not
perform as well as a 10Gb Sun system with 10 processors. Well, duh!
