I went through a number of different configurations on our Clariion.  The
best ended up being to take only 1 LUN from each raid group.  As many raid
groups as possible.
My main TSM server has 19 X 200gB raw volumes for its diskpool.  Each
volume is from a different raidgroup.

Just try not to use more than one lun from the same raid group.  That's
when I ran into performance issues.

Regards,
Shawn

[ADSM-L] New TSM Layout





We are in the process of designing our new TSM server. As part of this
we are also going to give it new SAN drive space.



Currently we have 661 Gig in our disk pool and we are upping that to 900
Gig. What our questions is how should we partition that? Our current
pool is in 7 partitions but I was thinking more like 3 or 4 partitions.
Are there any pro's/con's with going with fewer disk partitions?
