What type of hardware setups are you using, single core or ?? Do you have
any performance data based on what you want to create.

Hi Jim

Thanks for the response.

Part of the reasoning for separating the IO was due to performance
issues seen on other guests; we were looking at a minimum of 4 drives
for the application servers, not just one or two (not sure if I had
made that clear).

Following on from your response, is there any rule of thumb as to how
many to create, or what sizes to make the storage spaces ?

Making one large storage space will create I/O problems of it's own if
what my IBM resource has told me is accurate.

Do you have any best practise guidelines for this aspect ?

Evan,

Based on your description of the situation, I think most will agree that
best practice would have you create your storage spaces in SYSBAS. If
you isolate the drives for the storage spaces you will degrade the I/O
capacity to a point where I wonder if the performance of the guest
partitions would be sufficient. Allow IBM i to do what it does best,
manage storage.

If you had an iASP that had many disk units in it to eliminate the I/O
issues, then you could consider that. For now I would create the
storage spaces as needed and let them do their thing.
