Apologies for the typo in the earlier. I was able to initialize successfully. During the initial setup, 2 NIC option was selected and disconnected NIC3 and NIC4.
I have a query regarding the VXRail initial setup. I have 3 x E560F servers, which comes with 4x10G SFP+ connectivity.  During the initial setup, Is it possible for me to configure the VXRail with 2x10GSFP+ . And later on configure the unused 2x10G SFP+ dedicated for VM traffic? Any issues in the above configuration. Is this a good practice.
