Couldnt agree more, with fabrics going to 100 and 200 Gbps, fc is struggling to stay alive. Having a solution for NVMEoF crippled over a 32 Gbps link is not a smart idea. Some solutions work with 32 NVMe devices, with theoretical bandwith of 32 x 3 GBps. Even one NVMe flash drive saturates fc32.
I dont see value in a fc san anymore. Even a SAS link is 4x12 Gbps these days, fc is dying a slow death
