RE: Guide to Configure/Deploy New Power9 Box and LPARs using vHMC -- MIDRANGE-L

Rob offered many good links.

Only other suggestion is plan and layout all your VLAN tagging. My first go around I did not, and it can get confusing.
You have up to 500, so don't be afraid to space them out.
I allowed a range for each LPAR, and I keep them the same across LPARs.
Also, don't skimp on your NWSD and NWSSTG.
On my host LPAR, I created CLs for creating the NWSD, NWSSTG, NWSSTGL, a set of these for each client.
My large client has 10 NWSD, each with 7 NWSSTG, NWSSIZE of 214580 each, total of 70 arms.
More arms the better.
Smaller clients have fewer NWSD, each with 7 NWSSTG, NWSSIZE of 107290.

Rob,

I absolutely see where you (and everybody else) are coming from, and I understand fully what you mean. I had no ill-intentions when bringing up this question, but thank you for the honest reply!

Take care everyone!

Ok, I made this a separate reply.
If you are hosting client lpars for actual paying clients you are over your head.
You failed to communicate effectively with the BP who sold you this system.
You probably should have paid a little extra for consulting hours on getting this set up. Heck our BP gave us a few hours with our sale and we used that for just this stuff. We actually have a few credit hours from IBM we used for DB2 performance tracking and other stuff and a little more for maybe taking another look at DB2 Web Query.
There are some good people on this list who have not yet replied and it may well be that they look at you as a competitor as they host sites. That and rule 0fh at https://smex-ctp.trendmicro.com:443/wis/clicktime/v1/query?url=https%3a%2f%2fwww.frankeni.com%2fFrankenRules.html%2312h&umid=ae8f27ff-b8b8-4d55-9364-474619eb5ce2&auth=438b0784514c1757bd202125ca4db8b0abdb021e-2962b58aecd75bd50f434d38df4a04daa526ada0 Oh, and one of them is at a data center today doing work, and some of that is being paid for by my employer.

Evan/Paul,

Thank you for your responses so far. Good content.

Evan, thank you for the input on consuming i licenses when going down the path of i hosting i. Good to know.

I see also that the disk is all internal, so it probably comes down to
what

has been ordered as to which is actually viable.
The disks that were ordered for this box are ESJBs, and in my reading today I found out that these disks, although identical to ESJAs, are identified by IBM as disks used by IBM i.
https://www-01.ibm.com/common/ssi/ShowDoc.wss?docURL=/common/ssi/rep_sm/5/89
7/ENUS9009-_h05/index.html&request_locale=enwww-01.ibm.com

When this box was ordered it was primarily meant to be used for hosting customer LPARs spread across different versions of i, as well as in-house development partitions of i. Linux on Power was more of an afterthought (we currently have Linux only on x86 hardware). So now I'm wondering if I can even get VIOS up on this box, or if I will have to go down the route of i hosting i/Linux. We still plan on using it for the original purpose, but I was hoping to get some extra bang out of the hardware by adding Linux LPARs.

Am I missing something here? Can I still host Linux LPARs with ESJB disks?
