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.

The arcmsr driver first appeared in FreeBSD 5.4.


The driver was written by Erich Chen <erich@areca.com.tw>.


The driver has been tested on i386 and amd64. It likely requires additional work to function on big-endian architectures. ARCMSR(4)
