Areca RAID controller ARC-1880ix-12 (firmware 1.50) hangs when on high load.
My setup is:
Chenbro 3U chassis
Intel S5500BC mainboard
Xeon 5603 CPU
16GB of RAM
12 Seagate SAS drives ST32000645SS (2 of them as hot spare, 10 as RAID10)
Mellanox Infiniband HBA card
This server is working as external infiniband storage for Xen VMs. When load is quite big Areca's firmware hangs - it becomes unreachable even from Areca's ethernet adapter. After resetting the server power it returns to normal operation.
While Areca is hanged I can confirm that it is powered (ethernet link is active) and Infiniband HBA works Ok.
Thanks in advance for any idea or suggestion where the problem might be!
