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.
