• Strip Size
This parameter sets the size of the stripe written to each disk
in a RAID 0, 1, 10, 5, 6, 50 or 60 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 the cache strip size.
• Cache Mode
The SAS RAID controller supports “Write Through” and “Write
Back” cache.
•
Tagged Command Queuing
The “Enabled” option is useful for enhancing overall system
performance under multi-tasking operating systems. The
Command Tag (Drive Channel) function controls the SAS
command tag queuing support for each drive channel. This
function should normally remain “Enabled”. “Disabled” this
function only when using SAS drives that do not support
command tag queuing.
• SCSI Channel/SCSI ID/SCSI Lun
SCSI Channel: The SAS RAID controller function is simulated as
a external 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 SAS 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 SAS
controllers treat each LUN like a SAS disk.
