Yes, you can do multiple i5/OS partitions, but you need an additional
feature that enables virtualization. Also, because of disk attachment
issues, you will only be able to run two i5/OS partitions on a 515.
The constrainment is artificial AND intended.
I've already setup 515 for customers, performance is not different from
a vanilla 520 Express (contrary to what i've hoped). As a performance
test, I've used the administrative HTTP server.

I guess this begs the question of what the TRUE performance would be on
a maxed out 515 ?
We were thinking about adding one of these for development, but can we
do multiple OS/400 (i5/OS) partitions ?
Also it seems artificially contrained at 8gb of memory and 560gb of
disk.

You have to realize that when people talk about a 515, it really doesn't
have 3800 CPW. CPW is measured with max memory and max disk, but a 515
is
constrained by only 16GB of memory, and all the disk must reside in the
CEC, no HSL connections, nor external disk. Therefore, you would never
be
able to get 3800 out of a 515.
Its a fantastic box, and unbelievable when you look at price vs
performance, but you won't get 3800 CPW from the box. Now, when you
talk
about power 6, you are going to have much higher clock speeds on the
CPU,
which will make the CPU intensive jobs run better, but remember that
most
i5s tend to be constrained by I/O. So, as you increase clock speed, you
must also increase the speed of memory, the speed of the bus, and the
speed of I/O to really get the best performance.
