VMWare is not VIOS. VIOS has a very different mission, to be one of the
virtualization tools inside PowerVM.
Trying to compare them beyond basic functions they both perform is not a
worthwhile endeavor. While basic virtualization functions are much the
same, the methodology, hardware etc., could not be more different.

Hello Jim,

It would not make sense anyway to virtualize storage over a
virtualized layer. VIOS requires all it's storage to be direct
attached. (for that reason)
I understand you think big. :-)
For smaller shops, having some alternate (cheaper) means of (shared) storage
for the virtual guest disks could make sense.
I don't understand what you try to say with your virtualized virtualization
layering. The NFS server is supposed to be real hardware. Otherwise, you'll
create an interesting situation when a power outage happens. Recursion: see
recursion. :-) And yes, it's possible to shoot yourself in your own foot
with recursive storage using Vmware ESXi, as I've seen (and heard the
cursing from the customer's server room). :-D
At my employer, I'm running around 150 Linux- and Windows VMs with 8 servers
stored on a mirrored NFS server over 10GbE with very decent performance.
It's always a question of knowing which knobs to turn. ;-)
