All the RAID set volume management is done via the card BIOS. Although the controllers are actual RAID controllers the driver makes them look just like SCSI controllers. All RAID configuration is done through the controllers' BIOSes.

The cac driver first appeared in OpenBSD 2.9.
The cac driver was written by Michael Shalayeff <email@example.com>, in- spired by the NetBSD driver by Andrew Doran <firstname.lastname@example.org>.
The card provides a mechanism to receive asynchronous notifications about RAID set status change and so forth, unfortunately this information is not public. Only a few PCI cards were tested, but others should work. MirOS BSD #10-current December 17, 2000 1
