Disk Array Configuration of Built-inHard Disks
For the disk array configuration of hard disks installed in the built-in 3.5-inch device
bays, the disk array controller board of an option is installed in the server and the SCSI
cable connected to the Ultra320 connector is disconnected from the connector and then
connected to the disk array controller board instead. The server can be equipped with
up to four disk array controller boards.
Some disk array controllers contain more than one channel. For such a disk array
controller, you may connect one of the two channels to the built-in SCSI backboard
joined with the hard disk in a 3.5-in device bay and the remaining channel to a
additional disk unit. A disk array controller of another type has two connectors in a
channel, or external and built-in connectors. Note that a single channel may not be used
for both external and built-in devices.
