set (four pairs), but it can not support expansion and

• 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 6Gb/s SAS RAID controller function is simu-

lated as a external SCSI RAID controller. The host bus is repre-

sented 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 6Gb/s 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 6Gb/s

SAS controllers treat each LUN like a SAS disk.
