arcmsr -- Areca 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, 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 accelera-
tion 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.
By default, the driver will use MSI if it is supported. This
behavior can be turned off by setting this tunable to 0.
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 <firstname.lastname@example.org>.
The driver has been tested on i386 and amd64. It likely requires addi-
tional work to function on big-endian architectures.
