I have a server running Nexenta with a QLogic QLE2460 in target mode. This works great. My problem is that with that I only get 1 port worth of speed (4gbps) to my switch. How can I increase the speed. Now I will point out that I am no expert on Fibre Channel, but in networking I can hold my own. If this was networking I could team the nics and get the speed from both. Can I do the same with the Fibre Channel cards as targets? I did find some documentation on using QLDirect Filter to do this for the initiators, but what about the target? Am I better off putting the LUNs on different ports and try to get better speed by segregation?

Who is consuming this data? Are you actually seeing bottlenecks?
And remember, it's not always about throughput. Have you taken time to understand your I/O patterns? The mix of read to write? The nature of the transfers?
Can you give more information about the setup?
