VIOS does possibly give more flexibility, but also more to learn and
maintain.
Years back, not everything could be virtualized using i hosting I, but
that is no longer true.
Now, you can virtualize everything with i hosting i, CPU, MEM, DASD,
Ethernet, even Tape or Tape libraries with the latest IBM PTFs.
I'm i hosting i, with actual HMC, 7063-CR1.
Not sure if any limitations with vHMC vs HMC.

Food for thought.

Actually I take that VLAN tagging comment back, I think you can do it
on the HMC virtual adapter.

Hi Jacob
I've done a lot of i hosting i over the years, but I would favour
VIOS generally as my first choice for hosting.
- The dual vios set up provides a lot more redundancy and robustness
- I would prefer not to use i license capacity just for hosting
If you are primarily an i shop its true that the i hosting is
relatively easy to get going, but VIOS is designed to do hosting and
has a lot of flexibility whereas in the i's case it is just another
thing that it is capable of doing so you might find it lacks some
flexibility for instance VLAN tagging on network adapters.

How much and what type of DASD, how many physical arms do you have?20.46TB SSD (1.86 TB Mainstream SAS 4k SFF-3 SSD, x11). All
internal storage. No expansion drawers.
How much memory?256GB RAM (32GB DDR4, x8)
How many CPUs?8-core box, with 3 cores currently licensed.
How many Ethernet?12 ethernet (PCIe2 4-port 1GbE, x3)
How many FC?One 2-port card (PCIe3 16Gb 2-port Fibre, x1)
Are you planning on using VIOS or i hosting i?Haven't made up my mind yet. Was leaning towards VIOS, but we are
an i shop.
Hopefully others can chime in here with pros/cons of VIOS vs. No VIOS.
How many IBM i and how many Red Hat?At least 2 IBM i (for software development) and probably 4 Red Hat
(WebSphere/Nginx).

I have 4 LPARS, with my main LPAR being the host, non VIOS, i hosting i.
Another option would be that the host LPAR only does hosting,
doesn't run any applications.
In my case, my main LPAR is both my host and production LPAR.

Hello,
I have been given the opportunity to learn how to set up a new
Power9 box
(9009-41G) from scratch. This box will be used for hosting IBM i
and Red Hat LPARs. It has no pre-installed software. I was able to
successfully bring up the vHMC appliance in a Linux KVM Hypervisor.
The vHMC is running at version V9R2, M950, with fix MH01881 already
applied. I have not connected the vHMC to the Power9 box yet.
Would someone be interested in providing a high-level overview of
setting up a new box with a virtual HMC that will be running IBM i
and Linux LPARs? I am no stranger to reading the manuals, so
something along the lines of "read this first, then follow this
one, and then this book" would be a great help to start off with.
(My Redbooks collection has grown quite a bit that I don't even
know which one to read first). Also, I do believe I am going to
want to set up two VIO Servers, as the common consensus is to do it
and thank yourself later.
Thanks in advance,
