Just figured I would add that I have just got my first unRAID server up and running. Hopefully someone finds this useful as I counldnt find any info compatibility on the card before I bought it
I am using a HighPoint RR 2740 and after upgrading to V1.1 firmware it seems to be working fine. I have 15 HDDs in my array (inc parity and cache), a mix of 2740 and MB ports.
I havent done any testing for sleep etc, and at this point I am not intending to sleep the server, just spin the HDDs down.
BTW i am Running V5.0 RC12a
