Hard Drive Connectivity (SCSI Specifics)
The RAID adapter supports up to 15 SCSI devices per SCSI channel. It supports up to 15 hard disk
drives (or 14 hard disks drives if one of the SCSI ID’s is occupied by a SAF-TE processor) per
channel of the SCSI controller (30 disk drives total for the dual channel SRCU32 controller).
Supported Hard Drive Technology
The IIR controller supports both Single-ended (SE) and Low Voltage Differential (LVD) devices
but it is recommended that you use only one type of drive technology (SE or LVD) on any one
channel at a time.
The IIR controller supports single-ended drives which operate at up to 40MB/sec depending upon
the speed of the drives attached.
The IIR controller supports Ultra-2 LVD SCSI devices operating at up to 80MB/sec and Ultra160
LVD SCSI devices operating at up to 160MB/sec.
✏
NOTE
If both SE and LVD devices are attached to the same channel/bus, the entire bus will operate at the
single-ended speed of the slowest device. See Table 6 for the maximum cable length distances that
apply to each mode.
The IIR controller is designed to use Ultra160 SCSI hard drives and is backward compatible with
older SCSI hard drive specifications. See Table 6 for the SCSI standards supported.
