One of the technologies on the horizon is CXL, which rides over PCIe5 layer2 networks. I have done a couple of searches, and can't find out much about it. I know it is early days, which is why I am asking here, if anyone has run into it.
I am trying to figure out if CXL is going to be very disruptive to networking as we know it.
On it's face it probably won't change things too much, but it does have some potential to disrupt things. e.g. why have a 100gb network card in a server if you can just attach the server directly to the core over CXL at 800Mb/s? and much lower latencies.
Admittedly gen1 and gen2 of the CXL switches will probably not allow this, but when they do, (in the immortal words of Doc Brown) "you're going to see some pretty serious..schtuff".
