A single NWSD can have 64 storage spaces linked to it. After that you
need another NWSD.

This guide, updated just this month, has lots of pretty graphs and
charts that show the affect of multiple storage spaces, and multiple
server descriptions. (Section 6.5)

Personally I haven't had the time to mess with large numbers of 'arms'
(storage spaces) but according to the document, 8 is the magic number.
(Note: Their chart doesn't go beyond 8 so maybe 16 would be better and
they didn't try?) Pete often references the number 6 but I believe as a
minimum, not the perfect number.

Good point Pete, but he was asking about Max.

Yes, there certainly is. You should have at least 6 virtual disks per
hosted partition to get really good performance when hosting IBM I on
IBM
i.

I am getting ready to configure a couple of IBM i on IBM i Guest
partitions today. I thought I had seen at one time a suggested /
recommended max number of storage spaces per vSCSI controller. Has
anyone
seen or remember what that number is?

Thanks
