And a lot of people do. Cellular and satellite internet is excellent for rural and certain business use cases. I have gigabit fiber, and I’m considering one of those in case the Internet goes out if fiber is hit or if we lose utility power (I have a battery backup system).
Yes. Those folks are scared when it rains too hard. The connection does become more unstable.
I still acknowledge that your point is valid for everyone else however.
I have this exact setup (R730 and ZFS), but I’ll have to disagree on not using TrueNAS. There are features you may want to use, and the logical separation of the zfspool from the rest of the server has been handy. I boot and store my VMs off of SSDs outside of the main NAS pool.
If you want to use a NVMe boot drive on a PCIE card, the server isn’t natively capable of it. You need to use a USB drive to bootstrap it with Clover. I forget the exact technical details. I have had no problems leaving it in the internal usb port over a couple years so far.
