• This setting allows the connection of multiple AR1000 RAID
systems or other SCSI devices. Channel 0 is assigned to the
host channel while Channel 1 and Channel 2 are assigned to
the drive channels.
• With this configuration, every drive channel supports up to 5
physical drives.
• Disk drives connecting to the two DA-BP5 SCSI backplanes
may have identical or different SCSI IDs.
• All DA3000 RAID controllers on the SCSI chain must have
different SCSI IDs.
