<p class="Pp">The <code class="Nm">arcmsr</code> 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 <span class="Pa">/dev/da?</span> device nodes. A
management interface is also present via the
<span class="Pa">/dev/arcmsr?</span> device node. Management tools for i386
and amd64 are available from Areca.</p>
