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):
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.

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