I/OAT and NetDMA on E3-1200v3 series

AB17 — Wed, 10 Sep 2014 02:16:36 GMT

Hi,

I have a few servers using Supermicro X10SLH-F/X10SLM+-F and I wondered...

The motherboard uses Intel I210 NICs by the way.

But still this is mostly processor related. I'm running Xeon E3-1241v3 on these.

I would like to know if this kind of specs support NetDMA and I/OAT

Since NetDMA needs I/OAT, basically, the question is... does the E3-1200v3 series support I/OAT?

I have stumbled accross an Intel document : http://download.intel.com/support/motherboards/server/sb/g84364004_s1200v3rp_tps_r1_3.pdf http://download.intel.com/support/motherboards/server/sb/g84364004_s1200v3rp_tps_r1_3.pdf

It states under 3.3.7 and 3.3.7.1 that E3-1200v3 series do not support DCA and I/OAT2

However it really talks about I/OAT2, that is, version 2.0

So I know my hopes are dead for DCA.

But what about I/OAT? Not the 2.0 but just I/OAT? Is it supported by these processors?

Thanks

Thanks for joining the Processor community.

I understand you are looking for I/O acceleration technology for processor model E3-1241v3.

I am currently researching on this issue. As soon as I can, I will send you a message with my findings. Thank you for your patience and understanding.

Allan.

Thank you for your patience. The following is the response from our engineering department:

The server board and the processor do not support I/OAT or NetDMA.

Thanks

Allan.
