I know that the recommendation is to use as many physical volumes as
possible.  In the near future, volumes are going to become available to
me to use as many as 15 volumes per database instance.

Here is what I am wondering.  It seems that, if I create a 5GB volume
per disk, for a total of 75GB capacity, that TSM would tend to write to
one volume for quite some time if it were JBOD.  If I made it striped,
if I understand striping correctly, it will put the first chunk on the
first disk, second chunk on the second disk, etc.  Then create one large
DB vol, which will effectively be spread across multiple volumes without
me having to make sure of the housekeeping.

Any ideas, or real world experience?

For the record, in case anyone asks, I will be at TSM5.3 by the time I
do this, using a Fastt700 for the database volumes.

Thanks!
