NAME

arcmsrAreca 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, 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.
