January 13, 20224 yr hey guys!! im trying to do a direct connect from a windows 10 Pro machine to an unraid 6.9.2 machine. i bought 2 MNPA19-XTR 10GB Mellanox ConnectX-2 cards and a 35' sfp+ cable. Both the windows machine and the Unraid machine see the card just fine, I can move data between folder and edit file names without trouble. the problem arises when i try to move data between the machines. The transfer speed drops to 0, if i get any transfer speed its in the low kb range. I have posted my unraid diagnostics. Not sure if there that type of function for windows thanks for the help!! im still very new to unraid!! chris badwolf-diagnostics-20220113-0637.zip
