NAME¶
arcmsr — Areca SATA II RAID Controller driverSYNOPSIS¶
To compile this driver into the kernel, place the following lines in your kernel configuration file:device pci
device scbus

DESCRIPTION¶
The arcmsr driver provides support for the Areca ARC-11xx and ARC-12xx series of SATA II 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.HARDWARE¶
