SCSI Device and Driver Recommendations
SCSI Controllers:
 For reliable playback of real-time 16-bit and, especially, high definition material on Mac OS
10.3 and above, users must upgrade to the most recent version of the drivers for the ATTO
UL3D (version 3.2). The ATTO ExpressPCIPlus version 2.1 is recommended for use with Mac
OS 10.2.8. Please refer to www.attotech.com
for more information on updated drives.).
 Do NOT attempt to operate CinéWave with two single channel SCSI cards instead of the
approved dual-channel SCSI cards.
 Be sure that the number of drives is the same for both channels of the SCSI controller in order to
achieve balanced performance (e.g. 1+1, 2+2, etc.).
SCSI Cabling:
 Ultra 160 certified cables and terminators must be used with ultra 160 drives. (One of each is
required per channel.)
 Two channels are used, so two identical cables and two identical terminators are needed.
 SCSI cable lengths should match and not exceed 3 meters (shorter cables equal better
performance). Fiber cables do not have this same limitation.
 Ultra 320 drives require Ultra 320 cables and terminators. (One of each is required per channel.)
RAID Array Recommendations:
Striping Software:
 ATTO Technology’s ExpressStripe version 3.0 has been qualified for use with CinéWave.
 If you have trouble formatting your drives with ExpressStripe, it might be necessary to first erase
the disks with Apple Computer’s “Disk Utility”. This should only be necessary if you have first
used the Apple utility to stripe your array.
 Apple Computer’s “Disk Utility” can be utilized to setup a striped set.
 A software RAID 0 configuration is needed for maximum performance with either ATTO’s
ExpressStripe or Apple Computer’s “Disk Utility”.
