I want to learn if we will use "ConnectX-4 LX" model card on the HP Servers ( OEM Card Model 817753-B21 ) it can be connect between servers without switch or require switch ? ( we use "ConnectX-4 LX" for SMB Direct on S2D )
if applicable without switch!.. Can i use 25Gbps bandwidth with SFP+ between two cards ?
At first, unfortunately you can't...:(
You must have a DCBX switch that support loseless ethernet network.
Have a nice day!
