Crhis:
I suspect not all workloads are the same. What we are finding out is that
loads are taking place much faster. That was a large pecentage of our
usage before. We don't have any users signed on and we only run the zLinux
image to service requests. It works for us and no one is complaining.

Please respond to
Linux on 390 Port
Are you getting that much performance out of an IFL? Four times the
performance of a single RISC unix server?
I say that because the Oracle database we moved from an HP server with 2
PA-RISC 8600 (440mhz) cpus consumed a little more than one IFL(100%-120% on
a two IFL LPAR).
This was about in line with what IBM recommended.

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!
