Initialization Mode

Press Enter key to define fast initialization or Selected the Back-
ground (Instant Available). When background Initialization, the
initialization proceeds as a background task, the volume set
is fully accessible for system reads and writes. The operating
system can instantly access to the newly created arrays without
requiring a reboot and waiting the initialization complete. when
Fast Initialization, the initialization proceeds must be completed
before the volume set ready for system accesses.

Strip Size

This parameter sets the size of the stripe written to each disk in
a RAID 0, 1, 1E, 5 or 6 logical drive. You can set the stripe size
to 4 KB, 8 KB, 16 KB, 32 KB, 64 KB, or 128 KB.
A larger stripe size produces better read performance, espe-
cially if your computer does mostly sequential reads. However,
if you are sure that your computer does random reads more
often, select a smaller stripe size.
Note: RAID level 3 can't modify strip size.
•

Cache Mode

The SATA RAID controller supports Write-Through Cache and
Write-Back Cache.

SCSI Channel/SCSI ID/SCSI Lun

SCSI Channel: The SATA RAID controller function is simulated
as a SCSI RAID controller. The host bus is represented as a
SCSI channel. Choose the SCSI Channel.
SCSI ID: Each SCSI device attached to the SCSI card, as well
as the card itself, must be assigned a unique SCSI ID number.
A SCSI channel can connect up to 15 devices. The SATA RAID
controller is a large SCSI device. Assign an ID from a list of
SCSI IDs.
SCSI LUN: Each SCSI ID can support up to 8 LUNs. Most SCSI
controllers treat each LUN like a SCSI disk.

Tag Queuing

The Enabled option is useful for enhancing overall system
performance under multi-tasking operating systems. The Com-
mand Tag (Drive Channel) function controls the SCSI com-
mand tag queuing support for each drive channel. This func-
