If you have to pick a model - I would go with the 3390-3.. best for paging, etc.
My current customer is using mod9's with PAV -- no issues, although I think their paging performance would be better with mod3's for paging volumes. 3390-27 I would reserve for guests (such as Linux) which can use that much space all at once - or for CMS guest minidisks. I doubt there is any problem using them for the z/VM system volumes, but I definitely would not use them for paging. Others can probably speak with more technical detail about what's preferred and why.. Scott On Tue, Mar 31, 2009 at 4:29 PM, <[email protected]> wrote: > > I plan to install z/VM5.4.
