RE: Improve Performance of CRTNWSSTG -- MIDRANGE-L

Are adapter ids unique only to the LPAR or across all LPARS?
In other words, can each LPAR have adapter id from 1 to 500?

How many virtual adapters can each LPAR have and what are the limits.

Depends on how many you tell it to support.
On my hosting lpar I told it to support up to 500 "Maximum virtual adapters". I don't think I'll be hitting that limit any time soon.

________________________________

Normally I do create multiple NWSD and smaller NWS.
Currently on my Production LPAR, I have 5 NWSD with 6 100gb NWS hosting R&D LPAR.
No issues.

For this sandbox test, I just want to get the NWS space created to test the BRMS recovery.
On the HMC in the profile, I didn't have the extra virtual adapters available on this LPAR for additional NWSD.

Leads me to another question.
How many virtual adapters can each LPAR have and what are the limits.
This is something I want to preconfigure on the new P9 HMC, because it takes a power down of the host LPAR to change these in the profile.
A real PIA.

Haven't done any recent time trials lately.
We still have some spinning disks. However we reserve the 10k spinners
for archive data only.

Comments:

Good thing you're testing this now. All the more reason not to have your
production lpar be your hosting lpar on the box. Avoid the time crunch.

I tend to use smaller storage spaces. Much like the "arms" debate it may
help to keep your storage spaces roughly the size of drives commonly used
in production on IBM i. I almost always shoot for at least six storage
spaces per lpar. But I don't deal with tiny cloud hosting lpars. If I
will need more than 10 storage spaces I will start to spread those across
multiple NWSD's per lpar.
At this time my storage spaces are either 140GB or 280GB.
Multiple storage spaces and multiple NWSD's will have a positive impact on
your guests.

When I first started I used to create one huge drive per lpar. I've since
rebuilt that from the ground up.

On one of my sandbox LPARs, I'm creating some NWS for a BRMS recovery test
on a temp LPAR.
CRTNWSSTG is taking a long time.
Which additional resources would improve this, CPU, MEM, other?
P7 8205 8gb mem .1 CPU 10k spinny

CRTNWSSTG NWSSTG(P08CRST1) NWSSIZE(600000) FROMNWSSTG(*NONE) FORMAT(*OPEN)
ASP(1) TEXT('P08 Rst 1') OFFSET(*FORMAT)
Creating NWS storage space P08CRST1: 205056 of 600023 megabytes
complete.

90 minutes and only 1/3 complete.

Thank You
