NAME

     arcmsr — Areca 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, ARC-12xx, ARC-13xx, ARC-16xx and
     ARC-18xx series of SAS and SATA 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.

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 additional work to
     function on big-endian architectures.
