ARCMSR(4)                BSD Kernel Interfaces Manual                ARCMSR(4)

NAME
     arcmsr -- Areca SATA II RAID Controller driver

SYNOPSIS
     device arcmsr
     device pci
     device scbus
     device da

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 inser-
     tion/removal, automatic failover and rebuild, and SMART are also sup-
     ported.  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 avail-
     able from Areca.

HARDWARE
     The arcmsr driver supports the following cards:

     o   ARC-1110
     o   ARC-1120
     o   ARC-1130

HISTORY
     The arcmsr driver first appeared in FreeBSD 5.4.

AUTHORS
     The driver was written by Erich Chen <erichATareca.tw>.

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