RE: Improve R&D LPAR poor disk performance (10K spiiny) by using virtualized SSD from Production LPAR

Rob,

So it's better smaller/but more NWSTG?

Go with the 6/nwsd

Do not consider me the expert on this as these recommendations are constantly being updated. Normally Sue Baker, Larry Bolhuis and others have some input on this. But it is summer, ...

Rob,

I've finished crunching my numbers.
On my Production LPAR, I'm around 45%. 7TB total.
I'm planning on virtualizing 3tb, which will be about 42% of my current
available.
This will put my Production LPAR around 87%.

Should I create 30 NWSTG of 100gb each or 10 NWSTG of 300gb each?

I already have 5 NWSD created.

Each NWSD could/would have either 6 NWSTG or 2 NWSTG, depending on which
config I use.

I'll be shortly spinning up a new lpar.
We added a new disk enclosure to one of our Power 8's. The only disks in
that disk enclosure are these:
Serial Resource
Number Type Model Name Capacity Status
Y68008GE813A 59DD 050 DMP053 1729739 Non-configured
Y68008GE3RDA 59DD 050 DMP051 1729739 Non-configured
Y68008GE709A 59DD 050 DMP055 1729739 Non-configured
Y68008GDYXSA 59DD 050 DMP057 1729739 Non-configured
Y68008GE7LHA 59DD 050 DMP059 1729739 Non-configured

1.7TB drives.

I'll add them to the hosting lpar into a new ASP.
Then to use them on the guest I'll do this CRTNWSSTG ... ASP(2)

This new lpar is strictly old archival Domino data. Seems like an ideal
fit for these drives.
