I think that even the at that time the information about latency is incorrect as if RDMAoCE is used then the latency drops to microseconds when SSD or NVMe is used. Nowday ESXi has NVMe over CE And I think that destroys older fiberchannel solution when 10G is used, with anything faster the FC is pointless.
@@ixflqr Exactly, the problem is that FC starts to be way slower than Ethernet: FC 133M->266M->533M->1G->2G->4G->8G->10G->16G->32G->64G (2019) Eth 10M->100M->1G->10G->25G->40G->100G->200G->400G (2019) The only argument can be backward compatability for old FC instalations.
Agreed, understand the requirements and know the budget.
Great video 👍
However, present day 2023 Ethernet speeds have evolved since.

2:00 Well, you compare 10GbE vs 16Gbit FC. 10GbE is pretty old and is comming to consumer segment right now. Let's play this in 40 and 100GbE.
Even 400G (possible but improbable)
(Although 32G fibre channel is now available)
