I'm already spreading disks in a volume across the 7 SCSI controllers, but I'm wondering if there is also a performance advantage/disadvantage to spreading out the disks in a volume across the three IDE-to-SCSI bridges in each R100 disk shelf?
For example, if I wanted to create a volume with 3 disks, would it be better to pick three disks on the same bridge (like 3.0, 3.1, and 3.2) or would it be better to pick three across three bridges (like 3.0, 3.8, and 3.12) ? Or doesn't it make a difference?
Thanks,
Mark
