arcmsr — Areca SATA II RAID Controller driver
To compile this driver into the kernel, place the following lines in your
kernel configuration file:
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:
/dev/da? Array block device
/dev/arcmsr? Management interface
The arcmsr driver first appeared in FreeBSD 5.4.
The driver was written by Erich Chen ⟨email@example.com⟩.
The driver has been tested on i386 and amd64. It likely requires
additional work to function on big-endian architectures.
