These controllers support RAID 0, RAID 1, RAID 5, RAID 6, RAID 10, RAID 50 and
|
|
|
|
|
RAID 60 using either SAS or SATA II drives.
|
|
|
|
|
.Pp
|
|
|
|
|
Although the controllers are actual RAID controllers,
|
|
|
|
|
they appear as SCSI controllers.
|
|
|
|
|
All RAID configuration is done through the controllers' BIOSes.
