This is a hardware + software question. I'm setting up a file server running linux. I have a dual QSFP Mellanox Connectx-3 card in it. I'm wondering if I can set it up so that the card shows up as a single interface in linux with all 8 SFP+ (breakouts) running to different workstations but all on the same subnet. As if the card is a 9 port network switch with one of those ports arriving in the server.
Furthermore, would it be possible, if workstation #1 has a dual SFP+ NIC in it, to connect two of the SFP+ connections from the server to it and achieve a 20Gb/s link?
This would all be connected with DAC cables in the same room.
Lastly, are there SFP+ "couplers"? I've been looking around and haven't found such a thing. I want to use a QSFP to SFP+ breakout cable but I want to connect a short SFP+ to SFP+ DAC cable to extend one branch to reach two different machines.
