3.9.2 U320 SCSI Target Config

To set the U320 SCSI Target function, move the cursor bar to the main menu
and click on the

U320 SCSI Target Config

.

Channel 0 / 1 QAS:

The Enabled option supports Quick Arbitration and Selection (QAS). QAS re-
duces the overhead of control release on the SCSI bus from one device to
another. This improvement reduces command overhead and maximizes bus
utilization. Select the desired function.

Down To U160 IF U320 Unstable:

When Ultra320 signal transfer quality becomes terrible or bad, the RAID sub-
system will auto-speed down the transfer rate to Utra160 from Ultra320 in or-
der to keep the data transfer from being broken due to bad or poor SCSI
signal transfer quality.

Two TB CDB Selection:

12 Bytes CDB allows the RAID subsystem to support Over-2TB under Win-
dows Server 2003 (Must pre-install SP1 and driver) and Linux (Must pre-install
Linux patch). 16Bytes CDB allows the RAID subsystem to fully support Over-
2TB without any extra files or drivers pre-installed under Linux and Windows.
(Must use U320 and could not down to U160 if U320 unstable)
