Re: h/w vs. h/w+s/w

I believe you concluded that since 10+10 drives didn't get much
better performance than 4+4 drives, that the SCSI bus was
being nearly saturated by 4 drives.

My experience is that 8 drives on 1 bus wasn't much worse than
3+3+2 drives on 3 busses.  On that basis, I concluded that
SCSI bus saturation is not a problem for 8 drives on 1 bus,
and that something else is limiting performance.

Do you have comparable results for 8 drives on one bus?
