32 .Nd Areca RAID Controller driver
34 To compile this driver into the kernel,
35 place the following lines in your
36 kernel configuration file:
37 .Bd -ragged -offset indent
44 Alternatively, to load the driver as a
45 module at boot time, place the following line in
47 .Bd -literal -offset indent
53 driver provides support for the Areca ARC-11xx, ARC-12xx, ARC-13xx,
54 ARC-16xx and ARC-18xx series of SAS and SATA RAID controllers.
55 These controllers feature RAID-0, 1, 3, 5, 6, and 10 and
56 JBOD acceleration for up to 16 SATA drives.
57 RAID level and stripe level
58 migration, online capacity expansion, hot insertion/removal, automatic failover
59 and rebuild, and SMART are also supported.
60 Access to the arrays is provided
64 A management interface is also present via the
67 .\"Management tools for i386 and amd64 are available from Areca.
69 .Bl -tag -width indent
70 .It Va hw.arcmsr.msi.enable
71 By default, the driver will use MSI if it is supported.
72 This behavior can be turned off by setting this tunable to 0.
77 driver supports the following cards:
174 .Bl -tag -width ".Pa /dev/arcmsr?" -compact
186 driver first appeared in
189 The driver was written by
190 .An Erich Chen Aq Mt erich@areca.com.tw .
192 The driver has been tested on i386 and amd64.
193 It likely requires additional
194 work to function on big-endian architectures.
