NAME
     aac - Adaptec RAID driver

SYNOPSIS
     aac* at pci? dev ? function ?
     scsibus* at aac?

DESCRIPTION
     The aac driver provides support for Adaptec's "FSA" family of RAID con-
     trollers, including:

	   Adaptec AAC-2622, AAC-364, AAC-3642
	   Dell PERC 2/QC, PERC 2/Si, PERC 3/Si, PERC 3/Di
	   HP NetRaid-4M

     All the RAID set volume management is done via the card BIOS.

     This driver makes drives and/or RAID sets appear as sd(4).

SEE ALSO
     intro(4), scsi(4), sd(4)

HISTORY
     The aac driver first appeared in OpenBSD 2.9.

AUTHORS
     The aac driver was written by Niklas Hallqvist <niklas@openbsd.org>, in-
     spired by the FreeBSD driver by
     Mike Smith <msmith@freebsd.org>.

BUGS
     The card provides a mechanism to do online RAID set management, unfor-
     tunately the protocol is not public.

     Only Dell PERC 3/Si was tested, but others should work.
