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 .Pa /dev/da? device nodes. A management interface is also present via the .Pa /dev/arcmsr? device node. Management tools for i386 and amd64 are available from Areca. .Sh HARDWARE The .Nm driver supports the following cards: .Pp .Bl -bullet -compact .It ARC-1110 .It ARC-1120 .It ARC-1130 .It ARC-1160 .It ARC-1170 .It ARC-1110ML .It ARC-1120ML .It ARC-1130ML .It ARC-1160ML .It ARC-1200 .It ARC-1201 .It ARC-1210 .It ARC-1212 .It ARC-1213 .It ARC-1220 .It ARC-1222 .It ARC-1223 .It ARC-1230 .It ARC-1231 .It ARC-1260 .It ARC-1261 .It ARC-1270 .It ARC-1280 .It ARC-1210ML .It ARC-1220ML .It ARC-1231ML .It ARC-1261ML .It ARC-1280ML .It ARC-1380 .It ARC-1381 .It ARC-1680 .It ARC-1681 .It ARC-1880 .It ARC-1882 .El .Sh FILES .Bl -tag -width ".Pa /dev/arcmsr?" -compact .It Pa /dev/da?
