We have purchased a couple off 10Gb 2-port 561FLR-T put them I DL380 GEN8 servers and one HPE 5900AF-48XGT (10 GB switch). The cables are CAT 6 max length 2 M.
We have tried almost every settings, 10 GB full duplex on nic and switch. Testing different settings enable, disable Virtual machine ques, increase/de crease checksum, buffers and ………
Whatever we do the file copying never passes 300 MB/s .
What settings should I have on the NIC to get most throughput?
