We're setting up our new datacenter, EMC VNX 5300 connected via Fibre Channel, Nexus 5548UP fabric switches, and 2 Cisco UCS chassis. Since it's not live yet, I've had a chance to play around and get to learn a bit about Fiber Channel. As will be evident, this is my first foray into Fibre Channel and Nexus. I did come up with a bit of an odd question.
I have two Fibre Channel links between the Nexus 5548UP and the UCS fabric interconnects. I setup a 2 link SAN-Port-Channel on the Nexus and created the fibre channel port channel on the UCS side as well. The Fibre Channel port channel reported it's speed as 16 Gbps. That struck me as odd, so I checked the 4 link 10 Gbps Ethernet uplink port channel, which still reports as 10 Gbps.
I've done a bunch of reading, but don't have a clear answer as to the difference. I've read that the 4x 10 Gbps port channel is indeed 40 Gbps (even if it's not reported as such), but reports 10 Gbps because the individual packet flows are restricted to the speed of each link.
Does this restriction not apply to Fibre Channel? I can't seem to find much on that.
