These controllers support RAID 0, RAID 1, RAID 5, JBOD, and superpositions of those configurations.

Although the controllers are actual RAID controllers, the `ciss` driver makes them look just like SCSI controllers. All RAID configuration must be done through the controllers' BIOSes.

Hardware from previous generations of this product family may be supported by the cac(4) driver.
