connecting 10 Gb ethernet sx6018

My environment is one Mellanox SwitchX-2 SX6018 Managed FDR 18 port SDN Switch with Multiple Windows Server 2012 Clients connecting with Mellanox ConnectX-3 VPI InfiniBand Adapter Cards.

Is it possible to add a Mac OS X computer to the switch with 10 Gb Ethernet using a QSFP to SFP+ cable Adapter and SFP+ Optical Module and concurrently have Windows SMB direct over infiniband between the windows computers and have the Mac transporting TCP/IP to the Windows Servers?

Is this what the optional “Gateway” upgrade to the SX6018 switch is for?
