30.Sh NAME
31.Nm arcmsr
32.Nd Areca RAID Controller driver
33.Sh SYNOPSIS
34To compile this driver into the kernel,
35place the following lines in your
36kernel configuration file:
37.Bd -ragged -offset indent
38.Cd "device pci"
39.Cd "device scbus"
40.Cd "device da"
41.Cd "device arcmsr"
42.Ed
43.Pp
44Alternatively, to load the driver as a
45module at boot time, place the following line in
46.Xr loader.conf 5 :
47.Bd -literal -offset indent
48arcmsr_load="YES"
49.Ed
50.Sh DESCRIPTION
51The
52.Nm
53driver provides support for the Areca ARC-11xx, ARC-12xx, ARC-13xx,
54ARC-16xx and ARC-18xx series of SAS and SATA RAID controllers.
55These controllers feature RAID-0, 1, 3, 5, 6, and 10 and
56JBOD acceleration for up to 16 SATA drives.
57RAID level and stripe level
58migration, online capacity expansion, hot insertion/removal, automatic failover
59and rebuild, and SMART are also supported.
60Access to the arrays is provided
61via the SCSI CAM
62.Pa /dev/da?
63device nodes.
64A management interface is also present via the
65.Pa /dev/arcmsr?
66device node.
67Management tools for i386 and amd64 are available from Areca.
