Where does the SCSI go? Bad ASCII diagram follows (D=disk, C=controller H=host): SATA ____ D -------| | SCSI ________ D -------| C |--------| H | D -------| | |________| D -------|____| (etc. up to 16 drives) The drives and the controller go in the Chenbro case. U320 SCSI from the RAID controller in the Chenbro case to the 1U server. C
