I have an opportunity to redesign the disk pool and db layout of our TSM
Server , and I was wondering if my fellow TSMers can help me with it. First
things first our environment is as follows, TSM Version: 5.1.7 soon to be
5.2.? on Win2k, the Disk the DB will be stored on will be a RAID 5 Disk on a
EMC CX700 array.

My main question is can TSM read/write multiple streams to a single Disk or
DB vol? The reason why I ask this is that that would help me decide the
size/number of the volumes to the number of disks I am using in the RAID
array. For example, if TSM can only read/write a single stream to a disk
pool volume, I would create a group of disk pool volumes on a 170 gig RAID 5
array, containing 9 disks plus 1 for parity, with 9 disk pool volumes of
about 18.8 gigs. The reason I would do this is to optimize the I/O across
all the spindles.

Any help or advice would be appreciated.
