ARCMSR(4) Device Drivers Manual ARCMSR(4)


arcmsrAreca SATA II RAID Controller driver


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):


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
  • ARC-1170
  • ARC-1180
  • ARC-1110ML

The arcmsr driver first appeared in FreeBSD 5.4.


The driver was written by Erich Chen ⟨⟩.


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