  1. I am quoting Taobao prices. Also for ESP32 it would be hell to hot update them if you found a vulnerability. Linux-based solutions can be easily hot patched.
  2. OM3/OM4 4-fiber runs should be good enough unless you want to hit 400Gbps or beyond down the road. Also if you are renovating/building the house using optical fiber can reduce piping as fibers are often allowed to run along electric mains without breaking building code. Pairs of OM3 is also cheaper than Cat. 7 cables. Also optical media can carry protocols other than Ethernet, like Fiber Channel or Infiniband.
  3. If you have 40Gbps or 100Gbps link at the core and to your NAS and high performance NVMe storage there, you can have all your computers, even high performance workstations, stripped of their local storages, and boot exclusively over network. (Since by that time you have faster networking than PCIe 3.0 x4, which is slightly below 32Gbps.)
  4. My mistake. It would be more bang for the buck if you pass through miners' RX 470's instead of SR-IOV'ing what is effectively an RX 540.
  5. OM3 is already cheaper than Cat. 7, and Ethernet can go no faster than 10Gbps on copper at the scale of a home even on Cat. 8. (40Gbps over Cat. 8 only has a reach of 30 meters.) If you are doing that, keep in mind that future fiber standards over OM3 may require four fibers for a single link (up to 100Gbps links can run over two fibers over OM3, 400Gbps requires 4 OM3's per link to work.) So current setups should make provisions for that, and run those in bonded links now, to be converted to faster links in the future. Or if you don't mind the cost, go with OS1 single-mode fiber.
  6. Miners' RX 470 are likely better deals if you are just SR-IOV'ing.
  7. Fiber may make the building easier though, as depending on building code you may run fiber along electric mains in the same pipes, so a lot of electric piping work are gone.
  8. That card is RX 540 with PCIe x8 interface...
  9. What I mean here, is using fiber optics at the core of the home network, and to hook up desktop computers, when the home networking situation is not as simple as just a wireless router at the center. I am also talking about the cheaper stuff, like OM3 multi-mode fiber and 850nm transceivers. If Amazon prices are correct, it appear to me that OM3 fibers are cheaper than Cat. 7 Ethernet cables. If reliable 10Gbps+ is needed, maybe it would be cheaper to use OM3 instead.
  10. The specific board I mentioned, Orange Pi 2G-IoT, has a price tag between ESP8266 and ESP32, comes with both built-in Wi-Fi and cellular, and runs Linux. Built-in cellular would be a big bonus if you don't expect Wi-Fi to be available at all times, or you want to use something like SMS alerts.
  11. Anything to do before that? Like flushing caches or tell the system I am going to pull it?
  12. My chassis has a few hot swappable HDD bays, internally connected to a LSI SAS2008 based HBA card (ASUS PIKE 2008 flashed with IT firmware.) How do I safely eject a drive from that?
  13. Given the fact that you are likely going to have to implement big protocols like TLS1.3, I'd suggest a Raspberry Pi Zero W, or one of those Chinese alternatives like Orange Pi 2G-IoT. As of actually programming it, you can use your favorite language that is available on Linux - C++, Java, Python, Node.js, even Swift.
  14. If you want to put nVidia GPU in VM's I think the only cheap solution is hacking those Teslas into GRID's and pass them through using vGPU. As of passing AMD GPU, those mining RX 470's flashed with gaming VBIOS passed over SR-IOV are good options since those cards are cheap and lacked video output. Anyway, after it is done you can just put the server somewhere out of earshot, and use a bunch of Pi's in the rooms as thin clients.
  15. Since you have that much compute power, you can replace other PC's in the room with Raspberry Pi's acting as thin clients. Meanwhile if you have the funds, you may want to scoop up some of those 4TB Intel DC P4000 NVMe SSD's Facebook was dumping, and a maybe one of those nVidia Tesla cards that can be modded into a GRID. The former are just some cheap and fast SSD, and the latter will allow you assign virtual GPU to the VM's.
