Servers connected to NExus 5k were only getting 100 Mbps of throughput. So I disabled Flow control recieve on all the ports. After this we are getting 200 Mbps of speed. The servers are connected throuh 10 gig port. Could you guys please suggest why the throguhput is still low? Atleast we should get 1Gbps of thrpoughput.

Hi Adam,

I think we probably need a little more information to go on. Can you answer the following?

  • What type of servers and NICs?
  • What OS are you running on the servers?
  • What cables do you have from the servers to the switch?
  • Are the two servers in the same subnet or is the traffic between them routed?
  • If routed, is that in the Nexus 5548 or some other router?
  • How are you testing throughput?

Presumably you're not seeing any errors on the switch ports that the servers are connected to?

Regards
