Re: Size/number of guested storage spaces

Hi Rob

I've just set up a new guest partition for a customer recently and
found this document which might help:


http://www-03.ibm.com/systems/resources/systems_i_Virtualization_Open_Storage.pdf

This document also suggested a rule of thumb of 6-8 storage spaces per
i client (though I didn't exactly stick to this)

Interestingly there is a suggestion in this document to consider
configuring a separate ASP/IASP for the network storage spaces in some
circumstances. I wish I had known this earlier as it might have had
some effect on my thinking.

I also found this document useful:

http://www.omniuser.org/downloads/i5OS_hosting_i5OS.pdf

An also a performance capabilities document I located that I can't
find a link for right now.

I have some unload/reloads coming and instead of just migrating the
storage spaces from old host to new host I plan on busting them up after

Is there a MINIMUM recommended size? For example, V5R4 required a

minimum

load source size of 17GB

http://www-947.ibm.com/systems/support/i/planning/upgrade/v5r4/hardware.html

Power 5's will be the last to support the 17GB drives

http://www-947.ibm.com/systems/support/i/planning/upgrade/futurehdwr.html

If I take a 280GB system and bust it up into 6 drives that's roughly
46GB/drive. One of those links suggested making them the size of

standard

IBM drives (but no reason why). So, should I make them eight 35GB

drives?

And what is 'standard'? Rough answer would be 35, 70, 140, 280 but what
would one put on CRTNWSSTG?
