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 arcmsrAlternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):
arcmsr_load="YES"
DESCRIPTION
Thearcmsr 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.
