From what I understand it's basically like a "thin client" type of thing where the client loads the Kernel from local storage up to a certain point and then boots into a rootfs that is somewhere else on a remote server.
Basically, your system, if asked to, will boot into a limited mode where it exposes its drives over NVMe-TCP. It's like taking the hard drive out and putting it into a different PC, but over the network.
