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.

      tional work to function on big-endian architectures.
