While it is a very good raid controller it's driver is still GIANT LOCKED and i think this reduces perfomance of the server (they do a lot of disk io). Does anyone know a good raid controller (raid-5 not really needed, mirror is enough) whose driver is not giant locked? Or maybe i worry for nothing and this giant locked issue is not really affecting perfomance (we are talking 2 real CPUs configuration and sometimes 2 real + 2 logical (HT)). -- Regards, Artem
