The Alert Beeper function item is used to Disabled or Enable the
SATA RAID controller alarm tone generator.
•

Background Task Priority

The Raid Rebuild Priority is a relative indication of how much
time the controller devotes to a rebuild operation. The SATA
RAID controller allows the user to choose the rebuild priority
(ultraLow, Low, Normal, High) to balance volume set access
and rebuild tasks appropriately. For high array performance,
specify a Low value.
•

JBOD/RAID Configuration

JBOD is an acronym for "Just a Bunch Of Disks". It repre-
sents a volume set that is created by the concatenation of par-
titions on the disk. The OS can see all disks when this option is
selected. It is necessary to delete a RAID set if the disks in that
set are to be convereted to JBOD mode.

Maximun SATA Supported

The Controller can support up to SATA ll, which runs up to
300MB/s. NCQ is a command protocol in Serial ATA that can
only be implemented on native Serial ATA hard drives. It al-
lows multiple commands to be outstanding within a drive at the
same time. Drives that support NCQ have an internal queue
where outstanding commands can be dynamically rescheduled
or re-ordered, along with the necessary tracking mechanisms
for outstanding and completed portions of the workload. The
RAID subsystem allows user to choose the SATA Mode (slowest
to fastest): SATA150, SATA150+NCQ, SATA300, SATA300+NCQ.
