thanks, but in this there are no keys, key encryption keys, counters, deriavtion functions, or anything that would indicate how the security of identities and messages are preserved.
sure, sequence diagrams, which are great to have and necessary, but there are no assertions about how security is done.
Not really. Each card would only get 8 lanes. Then no more then two NVME drives will work in the storage card and that only if the board has bifurcation support.
Not sure why this is downvoted. Almost all (if not all?) consumer motherboards will drop the 2 x16 slots to x8 mode if you insert anything in the second slot. So using a PCIe riser for NVME SSDs means your GPU will get less bandwidth. This may or may not be noticeable, if you are running PCIe 4 the x8 will definitely not bottleneck the GPU, but x8 PICe 3 lanes probably will, especially for cards with less VRAM.
