Hello all
I'm working on 2 new servers, that will be used as fileservers for smb clients
Both servers are equipped with intel X710 , which is a 40Gb/s card, and we plan on using the 40Gb/s for connection between the two servers, for backup / synchronizing data
I'm looking for suggestions on tools to test network performance between the server , will tools like iperf be good for it ? or it's not meant for this kind of links ?
Also, any suggestions on tuning to get the best throughput out of the links is appreciated
Thanks in advance

Re: Testing/tuning 40Gb/s networking on CentOS 7
I presume there must be different models of X710 then as the ones I have are 4 x 10GbE not 40GbE.Both servers are equipped with intel X710 , which is a 40Gb/s card
iperf3 is in EPEL and, yes, it's designed for that very task.
The future appears to be RHEL or Debian. I think I'm going Debian.

I believe so, the one I have is XL710-QDA2 - Dual Port QSFP+

Thanks, any suggestion on tuning settings for the network ? Do you use jumbo frames or 1500 MTU ?iperf3 is in EPEL and, yes, it's designed for that very task.
Thanks
