The Areca controller is supported but only very basic infos are availaible as Areca doesn't provide much via SNMP. But there is a areca-hw script that uses the cli tool get the hardware infos out of it:

CLI> hw info The Hardware Monitor Information ===================================================== [Controller H/W Monitor] CPU Temperature : 64 C Controller Temp. : 38 C CPU Fan : 8437 RPM 12V : 12.220 V 5V : 5.053 V 3.3V : 3.360 V IO Voltage +1.8V : 1.824 V DDR3 +1.5V : 1.536 V CPU VCore +1.0V : 1.040 V Analog +1.0V : 1.024 V DDR3 +0.75V : 0.752 V Battery Status : Not Installed [Enclosure#1 : SAS RAID Adapter V1.0] ===================================================== GuiErrMsg<0x00>: Success.

Would it be possible to extend the areca-hw script to add volume and disk info to check if the volume is in Normal or Degraded state and if possible which disk is gone?
