Apparently it is Intel E5 supports DDIO and not a particular device. Any IO device like NIC or RAID will have advantage of DDIO on E5 system
I cant find any credible information on what this card exactly is. Intel X540 AT2 supports DDIO (Intel Direct Data IO). But for example X540 T2 doesnt (or at least it is not in the spec).. What is X540 DP which can be bought in R320 ? Does it support DDIO with Intel E5 CPUs ? This whole setup is expensive. I need to know for sure if does what I need.
Does R320 Intel X540 DP card supports DDIO ?
