Combine several ConnectX®-2 EN 10GbE?

Hi, i want to combine several dual-port ConnectX®-2 EN 10GbE cards on NAS server at home and connect client machines with single port ConnectX®-2 EN 10GbE card to each available port on NAS server via direct attach cable.

I run dualboot Win7/Fedora23 on clients and nas4free(freebsd) on server. Will this work? And if it will, will the clients be able to see each other or only NAS server?
