RE: IBM i vs VIOS for Host Partition



fixed


Pete - I bet if I go to my notebook and session schedule you are completely
correct!

My apologies... you have jarred my memory into correct focus.

Pete's session was excellent, as were the multiple sessions given by Larry
that I attended on other topics.

Chad,

Most people don't get Larry and I confused, as he is about 5
inches taller than me (and most other people as well).

Are you sure it was Larry who presented that session? Larry
does the session comparing and contrasting IBM I & VIOS as a hosting
environment, and I do the step by step guide to building IBM I virtual
partitions hosted by IBM i.

There was a good session at Common this year by Larry Bolhius dealing with
step by step setup of guest partitions hosting i.

We realize that we'll have to burn up some credits to get someone in here
to set up VIOS, while I figured out guest partitions on my own using this:
IBM i 6.1 Technical Overview
http://www.redbooks.ibm.com/abstracts/sg247713.html?Open
Pretty much did that step-by-step; something I find lacking in Infocenter.

VIO Server can run with both internal and external storage as can IBM i
hosting. I don't have partitions that are big enough to stress them out,
but customers have done both IBM i hosting and VIO Server hosting.
Neither one seems to outrun the other in the workloads they have (10K
transactions/hour with plenty of DASD arms), but there is a big difference
in the management of them. VIO Server might be slighly more flexible and
has a few features IBM i hosting does not, IBM i hosting is much simpler to
set up and requires a much lower learning
curve. I think the larger the environment the more VIO Server tends
to be the better choice, but that is very arguable.

This solution I believe requires SAN storage only.

I am curious about the Performance differences, if any, when
hosting
IBM i
on IBM i vs IBM i on VIOS. Are the 2 methods about the same?
Wildly Different?
Do I need more Memory or CPU generally speaking for one vs the
other
etc?

I don't need or want a discussion on what features/capabilities of
each
method, but just how well the guest partitions perform. Looking
for
real
life experiences and any book type references..

Thanks
