WEB BROWSER-BASED CONFIGURATION

The available RAID levels for the current Volume Set are dis-

played. Select a RAID level and press Enter to conﬁrm.

• Strip Size

This parameter sets the size of the stripe written to each disk

in a RAID 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 small 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

to the SCSI RAID controller. The host bus is represented to the

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 as a lots of large SCSI device. We should assign an

ID from a list of SCSI IDs.

SCSI LUN: Each SCSI ID can support up to 8 LUNs. Most SCSI

controller treats 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-

tion should normally remain enabled. Disable this function only

when using older SCSI drives that do not support command tag

queuing

To delete Volume from raid set system function, move the cursor
