ARCMSR(4)		    Kernel Interfaces Manual		     ARCMSR(4)

NAME
       arcmsr -- Areca SATA II RAID Controller driver

SYNOPSIS
       To  compile  this  driver into the kernel, place	the following lines in
       your kernel configuration file:

	     device pci
	     device scbus
	     device da
	     device arcmsr

       Alternatively, to load the driver as a module at	boot time,  place  the
       following line in loader.conf(5):

	     arcmsr_load="YES"

DESCRIPTION
       The  arcmsr driver provides support for the Areca ARC-11xx and ARC-12xx
       series of SATA II RAID controllers.  These controllers feature  RAID-0,
       1,  3,  5,  6,  and  10 and JBOD	acceleration for up to 16 SATA drives.
       Raid level and stripe level migration, online capacity  expansion,  hot
       insertion/removal,  automatic  failover and rebuild, and	SMART are also
       supported.  Access to the arrays	is provided via	the SCSI CAM  /dev/da?
       device	nodes.	 A  management	interface  is  also  present  via  the
       /dev/arcmsr? device node.  Management tools  for	 i386  and  amd64  are
       available from Areca.

       The arcmsr driver supports the following	cards:

          ARC-1110
          ARC-1120
          ARC-1130
          ARC-1160

HISTORY
       The arcmsr driver first appeared	in FreeBSD 5.4.

AUTHORS
       The driver was written by Erich Chen <erich@areca.com.tw>.

BUGS
       The driver has been tested on i386 and amd64.  It likely	requires addi-
       tional work to function on big-endian architectures.
