A long time back there was a discussion as to whether it's better to have one or multiple tsm volumes per physical disk. As I remember, the answer was: assuming the entire physical disk volume was being used by one storage pool, it was best to create one large tsm volume rather than several smaller volumes to avoid disk IO contention. I will be moving my db and log volumes stand alone disk to an emc symmetrix. Does anyone have a suggestion as to number of tsm volumes that should be created for each emc logical drive? Would it be best to put 1 4GB, 2 2GB, or 4 1GB database TSM volumes on 1 emc logical volume?
