Connect a server message block (SMB) drive, run RoCE traffic, and verify
the results.
To set up and connect to an SMB drive, view the information available online
from Microsoft:

By default, Microsoft's SMB Direct establishes two RDMA connections per
port, which provides good performance, including line rate at a higher block
size (for example, 64KB). To optimize performance, you can change the
quantity of RDMA connections per RDMA interface to four (or greater).
To increase the quantity of RDMA connections to four (or more), issue the
following command in Windows PowerShell:
PS C:\Users\Administrator>
Set-ItemProperty -Path
"HKLM:\SYSTEM\CurrentControlSet\Services\LanmanWorkstation\
Parameters" ConnectionCountPerRdmaNetworkInterface -Type
DWORD -Value 4 –Force
