initialization proceeds must be completed before the volume
set ready for system accesses. There is no initialization happed
when you select “No Init” option. “No Init“ is for customer to
rescue volume without losing data in the disk.
• Stripe Size
This parameter sets the size of the stripe written to each disk in
a RAID level 0, 1, 10, 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 cache stripe size.
• Cache Mode
The SATA RAID controller supports “Write Through” 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 SATA
RAID controllers treat each LUN like a SATA 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-
tion should normally remain enabled. Disable this function only
when using older SATA drives that do not support command tag
queuing
