Thank you for your answer.
I'm made a VPI Gateway with my 2 of SX6036G FDR Gateway systems on vSphere environment today.
Test was successful.
This system works like charm with Untangle 12 that running on Dell R310 physical system.
Sometimes later I'll add a pair of MCX354A-FCBT to my 10 of R610 ESXi hosts then configure that HCAs. One is for IB another is for 40Gb Ethernet. Each port on HCA will connect to sepersted SX6036G then I'll connrct to my Dell N2024's 10Gb port with Mellanox QSA...:)
