Thank you for shedding some light on it. I am still usure if the following setup will work with IB:
- 40Gbit IB switch
- storage server with 2-port IB 40Gbit card - both ports linked to the same IB switch
- 8 clients - each with single port 10Gbit IB card - all cards connected to above switch
Now, if I push 10Gbit from each client to the storage server
will I see 80Gbit incoming on the server? or just 40Gbit?
I can do above (8*10 ==> 80 and 80 ==> 8*10) with Ethernet (using bonding on server) but will thiis work with IB too?
Will it work out of box with every QDR IB switch or a special feature will need to be activated?
