ARCMSR(4) FreeBSD Kernel Interfaces Manual ARCMSR(4)
NAME
arcmsr -- Areca SATA II 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):
arcmsr_load="YES"
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.
HARDWARE
The arcmsr driver supports the following cards:
o ARC-1110
o ARC-1120
o ARC-1130
o ARC-1160

HISTORY
The arcmsr driver first appeared in FreeBSD 5.4.
AUTHORS
The driver was written by Erich Chen <erichATareca.tw>.
BUGS
The driver has been tested on i386 and amd64. It likely requires addi-
tional work to function on big-endian architectures.
