I am an advocate of FC Protocol. I love it. Much more then iSCSI. But I hate SAN Booting. It is a pain in the ass. And you need a Server to host the images. You have to build up a SAN Infrastructure. I guess 2 boot SSD's are cheapter. 2x 64GB NVMe SSD with a PCIe Card or 2x 64GB SATA SSD's cost next to nothing.
