How many tags? The default is only two unless you play around with the stuff around QUEUE_FULL_SUPPORTED in i386/scsi/aic7xxx.c These numbers seem rather low. What is the performance of the individual fujitsu drives. Running bonnie on a single Quantum Atlas will blow these numbers away. Are you doing RAID 5? Even with RAID 5, I would still expect much better numbers. -- Justin T.
