What is the maximum throughput we will achieve with XL710-QDA2 2x40GE NIC ? Since these ports are full-duplex support, I am assuming per port it will achieve 80Gbps totally (TX:40Gbps, RX: 40Gbps) ?

Jump to solution

From x710 data sheet page 7, i could see it support only 40Gbps, even when connected via two 40Gbps connections.

 

Per port it support 40Gbps both TX,RX Combined ?

Hi NYerr, After further verification, the total throughput is still 40Gbps even when connected via two 40Gbps connections. The XL710 controller is made to handle up to 40Gb/s and the second port was added for more versatility. Hope this answers your question. Please let us know if you have other assistance needed.

Hello Vince

 

You mean to say though these NIC ports are full duplex it will support max 40Gbps totally (RX,TX).

 

Is it possible for you to share throughput results, we would like see performance results with different packet sizes.

 

Thanks for you r support.

Hi Naveen, Let me check this internally, do you have specific packet sizes that needed to be part of the performance results? Best Regards, Vince T. Intel Customer Support Under Contract to Intel Corporation
