I'd even go so far as to say it'd be worth a few hundred extra dollars for another SCSI controller. That would not only make the setup more reliable but it should improve performance as well. Four of almost any modern SCSI drive exceeds the available bandwidth on a F/W SCSI bus. If you had any other SCSI devices (CD-ROM, tape drive, etc.), I'd even go for a third SCSI bus for those on such an expensive server. -- Steve Kanefsky
