You CAN have a bottleneck if you do not have same size drives. My predecessor chose to put 4gb and 9gb drives on the same Mod20 and we do have problems that I have to manage carefully or we see performance problems. If you don't have the time to manage different size disks, make sure all drives are the same size.

with just 1 disc array you create a bottle-neck, you have just 1 pipeline
for data to use. This gets ugly when you do lots of OLT and batch jobs at
the same time."
Doesn't the MOD20 support two FWD Scsi controllers? Couldn't both controllers be used to access the 10 drive. Map 5 to 5 mirrored?
Otherwise I could see there being a bottleneck in this environment.
Thanks,
