Well, it sounds like this machine is going to be 100% io-bound with simple-to-optimise linear reads and writes. This is something Linux is pretty well tuned for already. The best bet might be to set up md and put the SCSI disks in a RAID configuration. If integrity isn't important (all your datafiles are copies from somewhere else) then just plain striping will probably help a lot.
