Re: Guide to Configure/Deploy New Power9 Box and LPARs using vHMC

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,
