I'd try to find the correct MIB - Google shows up with this:
http://opennms.530661.n2.nabble.com/Adding-an-Areca-MIB-td5676020.html
which points to 
http://www.areca.us/support/download/RaidCards/AP_Driver/snmp-mibs-sas.zip

An snmpwalk gets much more interesting when used with a MIB otherwise
its like reading the Matrix.

The MIB is buggy indeed (as most vendor supplied mibs). To silence the
net-snmp warning i changed this:
