Chapter 5: Getting Started ● 23 Ultra320 SCSI on the Adaptec 29320LPE The Adaptec SCSI 29320LPE is a single channel SCSI card with a maximum throughput of 320 MB/sec. Ultra320 is an enhanced SCSI technology that transfers data at up to 320 MB/sec. Ultra320 SCSI allows cable length of up to 12 meters for optimal connectivity and flexibility. See About Your SCSI CARD on page 13 for more information. Note: For the best data I/O performance, Adaptec recommends that you keep your Low Voltage Differential (LVD) and non-LVD/SE devices separate. (LVD devices means Ultra320, Ultra160, and Ultra2 SCSI devices and non-LVD are Fast SCSI or Ultra SCSI devices.) Device Drivers An Adaptec SCSI card comes with a set of software device drivers and other files that enable it to communicate with your system. For information on how to install the driver for an Adaptec SCSI card, refer to the section of this User's Guide that describes your specific operating system. Selecting Cables This section describes the cable options and requirements for your SCSI card. For information about cable lengths, see Maximum Cable Lengths on page 21. SCSI Cables One six-position Ultra320 SCSI LVD cable with terminator is included in the kit. Depending on your requirements, you may need one 68-pin VHDCI external LVD SCSI cable (similar to the one shown below) for each external SCSI device you plan to connect. External SCSI cable-Connects to an external SCSI disk drive or device. Adaptec recommends using only high-quality Ultra320-rated cables with multimode terminators for all disk drives that share a channel with Ultra320 disk drives. Avoid poor quality cables, as they may degrade reliability. Do not use cables not rated for Ultra320 operation. Adaptec recommends using only Adaptec SCSI cables.
